Disposable cups can not be placed in the microwave oven
Disposable paper cups are classified into high temperature resistant and non-resistant high temperatures. If they can withstand high temperatures, they are marked on the bottom of the cup. However, they are generally resistant to high temperatures. Therefore, they cannot be placed in microwave ovens.
 Disposable paper cups are classified into high temperature resistant and non-resistant high temperatures. If they can withstand high temperatures, they are marked on the bottom of the cup. However, they are generally resistant to high temperatures. Therefore, they cannot be placed in microwave ovens.

 

The heat resistance of double wall paper cups and plastic cups is far from that of stainless steel cups or ceramic cups. Generally, they are only suitable for warm or cold drinks below 60 degrees. If put in a high-temperature microwave oven, it may release a large amount of bisphenol A substances that are harmful to human health, and dissolve into water or drinks into the human body. However, the information posted on the Internet “The paper cup is 30 times more toxic than the plastic cup” is not reliable.
Disposable paper cups and plastic cups are not promoted cups, because the quality of these two kinds of cups, crafts, etc. are still lacking strict national standards in China, and surviving standards are not mandatory, so that many contain double Phenol A or heavy metals, lead exceeding the "problem" paper cups and plastic cups flooded. Since it cannot be controlled, we must take precautions first. Do not put a paper cup and plastic cup in the microwave oven during the prevention of the harm caused by the unqualified cup.

New use of disposable cups

    Now more and more disposable cups are appearing in people's sights, whether it is family or company, disposable cups for visiting guests' doors, company training, disposable cups for meetings. So sometimes people joked that this is not only an era of rapid development, but also a one-time era.

    Responding to the trend of the times, we call everyone's environmental protection. This is what everyone is most concerned about now. How can we achieve energy conservation and environmental protection and not waste resources? In addition to minimizing or eliminating the use of disposable paper cups as much as possible, everyone else advocates waste recycling.
In many kindergartens, there are manual classes. Many teachers also cultivate their awareness of saving since childhood, so disposable cups come in handy at this time. Many children will write paintings on disposable cups, so that the original monotonous paper cups become rich and colorful, there are many children will cut the paper cup cut to form a lot of different patterns. This not only increases children's hands-on awareness, but also more importantly cultivates their awareness of conservation and environmental protection.
    Actually, in addition to these uses, disposable cups can also be used as a small trash can, some melon seeds or scraps of paper, etc. Of course, it can be used as a small flowerpot to raise some small flowers. Grass regulates the atmosphere of the office or home. Some people even came up with the idea that they can make disposable cups into "earth phones" to make them play. All in all, in short, all resources in the world can be recycled through human thinking. Garbage is just a misplaced resource, so let us act together to protect our earth resources.

With the accelerating pace of life, more and more disposable appliances are now appearing in our lives. There are many disposable paper cups in companies and in many families. This has become a fast-paced life. A must-have paper cup product.

Currently, the disposable cups in the market are mainly divided into three types: cardboard, waxed paper like double wall paper cup, and paper-plastic cups. And these three types of paper cups, our custom disposable paper cup manufacturers support the custom of the paper cup. Today, our factory technicians share with you about some issues that need attention when using disposable cups.

Many people feel that before using a disposable paper cup, it is only necessary to pour out the first cup of water and not drink. Actually, this is not entirely correct because if it is a cup produced by a non-regular manufacturer, even the first cup of water is not Drink and drain, it will not let the harmful substances evaporate out, so when choosing disposable cups custom manufacturers must choose qualified merchants with strict quality inspection, but also have to choose the cups are QS logo Certified paper cups, such paper cups are qualified products, there is no problem in the use of hot water. When choosing disposable cups for custom manufacturers, be sure to choose regular dining establishments to prevent later use of health-threatening situations due to incorrect selection.

We often use paper cups to greet our guests in our lives. But do you know that paper cups have a shelf life?
 Recently, a 7-year-old girl from Jiaxing, Zhejiang province, has had symptoms such as inflammation of her throat, coughing, red eyes, etc. because she uses expired disposable paper cups to drink water. Everyone can't help wondering whether food, medicine, etc. have a shelf life. Does a disposable cup have a shelf life?

The production date and shelf life are now printed on disposable cups sold in general supermarkets. The shelf life of different paper cups is also different. Some paper cups have a shelf life of up to 5 years. The quality of disposable cups on the market is uneven, and most households are not properly preserved, making the cup vulnerable to mildew and mildew, causing the growth of bacteria and fungi. This time, if used, it will cause some harm to the human body, it is easy to cause respiratory tract Diseases, etc. When consumers drink water on weekdays, it is best to use household cups and use disposable cups. When going out to play, try to bring a portable kettle, not only to drink water, peace of mind, but also environmentally friendly.

How to buy a qualified paper cup?

one look. First of all, to see whether the information marked on the package is complete, whether the production license number and the QS logo are marked. Secondly, the printed pattern on the outside of a good paper cup has a clear outline, uniform color, and no obvious stain. The cups of the qualified cups shall not have a printed pattern within 15 mm from the cup body and 10 mm from the cup body. Third, pay attention to the production date and shelf life.

Two pressures. Gently squeeze on both sides of the paper cup to roughly know the quality of the cup. Generally high-quality paper cups can hold water for 72 hours without leakage, and poor quality half-hours will seep.

Three smells. Smell paper cups have no pungent odors, especially the taste of the ink or moldy smell, do not generally buy odors.

When each product is released, the most important thing is his process, because the production of this is very important, others can not imitate:

1. PE Laminating Film: Putting PE film on the base paper (white paper) with a laminating machine. The paper on one side of the lamination film is called single-sided PE laminating paper. The lamination of both sides is called double-sided PE laminating paper.
 2. Slicing: The slitting machine divides the laminating paper into rectangular paper (used for paper cup wall) and web (used for paper cup bottom).

3. Printing: Use letterpress printing machine to print various patterns on rectangular paper.

4. Die-cutting: Using flat-press indentation and cutting machine (commonly known as die-cutting machine), the paper with good graphics will be cut into paper-shaped cups.

5. Forming: only need the operator to put the fan paper cup and the cup bottom paper into the feeding port of the paper cup forming machine. The paper cup forming machine can automatically form the paper for your needs by automatically feeding the paper, sealing and flushing the bottom. Various sizes of paper cups. The whole process can be easily operated by one person.
6, packaging: the prepared paper cup sealed with a plastic bag, and then packaged into the carton
 First, the quality of the paper ice cream bowl

Quality is the minimum requirement for a qualified product. The quality is not good, it is related to the customer's return rate, the secondary sales rate, etc. Even the quality problem has hit the store and the company's signboard.
 Second, the style of paper ice cream bowl

Style and design are faced with whether or not they can find a place in the paper ice cream bowl market. Good styles and designs can quickly become popular in the market and become hot items. paper ice cream bowls also have such characteristics.

Third, the price of paper ice cream bowl

What kind of price is the most reasonable and profitable space? Both buyers and sellers hold their own words. In fact, in the end, it is inextricably linked with the paper ice cream bowl manufacturers. If the ex-factory price is low, then the market price will decline, but instead it will be the opposite!

Milk is rich in nutrients and easily digested and absorbed by the body. It is an ideal food. With the improvement of people's living standards and the deepening of their understanding of dairy products, especially in recent years, with the development of science and technology, the types of dairy products have gradually increased, the shelf life is longer, and they are more convenient to carry or drink, and are deeply loved by the public. .
However, it is necessary to choose suitable packaging materials to prolong the preservation period of milk and ensure the quality of milk products. At the same time, it is conducive to storage and transportation, which is conducive to sales, and requires dairy enterprises to work hard.

High quality packaging materials provide longer shelf life

The choice of milk film. In order to ensure the quality of dairy products, we must pay attention to the health and safety of milk film. From suppliers, control suppliers strictly use food-grade raw materials, environmentally-friendly inks, and strictly enforce the required standards when testing, thereby ensuring product quality.

Uses packaging materials that have good oxygen barrier properties (ie poor air permeability). The film material used for the milk packaging film is mainly a polyethylene (PE) co-extruded film. The pros and cons of oxygen barrier properties of packaging materials are the direct cause of the shelf life of milk. When the packaged articles are exposed to the air, the oxygen molecules of the air penetrate through the molecular gap of the packaging material and penetrate the inside of the package directly into contact with the milk. When the transmitted oxygen reaches a certain amount, the milk will degenerate. With the development of the times, the milk packaging is packaged from the initial single-layer polyethylene plastic film bag to multilayer composite film. These multilayer composites incorporate polyvinyl alcohol or special coatings during the production process, which greatly improves the barrier properties of packaging materials to oxygen. The barrier properties (specifically referred to here as air permeability) are influenced by the production process, coating thickness, and materials. The impact of such factors.

In addition, in the face of a wide variety of milk on the market, consumer demand psychology and purchasing motivation have become the focus of many dairy products. Brands, prices, nutrition, and convenience have become the main factors for many consumers to purchase. In response, many companies regard how to tap and meet consumer demand as a guide for hot product development.

Paper cup packaging is extremely advantageous

kraft paper cups are fresh, elegant, hygienic, convenient and stylish, giving people a fresh look. It is used to package liquid milk or fermented milk in foreign countries, especially in Japan and Southeast Asian countries. And in the country is a new form of packaging. It was first applied by Shanghai Guangming Company in March last year and was very popular among consumers.

Compared with other packages, kraft paper cups have the features of convenience, novelty and high overall cost performance.

(1) Compared with roof packages, kraft paper cups are more convenient and economical to use. kraft paper cups are cheaper than roof packs;

(2) Compared with ordinary glass bottled milk, it increases the packaging cost, but greatly reduces the high complaint rate of bottled milk, reduces post-sale treatment costs, helps improve the corporate image, and meets the needs of consumers at different levels;

(3) Compared with plastic film bagged milk, kraft paper cups also increase some packaging costs, but the packaging looks elegant.

As the sale targets of kraft paper cups and roof packs, glass bottles, and bagged milk are different, the demand for new and old customers is met, differentiated sales are achieved, and the difference is increased, which brings additional profits.

Plastic appliances

The use of plastic containers, cups and other plastic utensils in households is becoming more and more widely used, especially in the summer. How to choose materials and ensure safety? Senior engineer Wang Zhenhua said that the bottom of the plastic product has a triangle with an arrow. The recycling mark, which has a number in the middle of the triangle, is a plastic material code that can be used to select different plastic materials for different purposes.

"1" stands for PET (polyester): common in mineral water bottles, carbonated beverage bottles

This beverage bottle can be heat-resistant up to 70 °C, suitable for warm drinks or frozen foods and drinks, high temperature liquids or heating is easily deformed, harmful substances will melt. After 10 months of use, PET may be aged and release harmful substances. Therefore, when the bottle is used up, it should be discarded in time, and it should not be used as a cup or recycled for a long time.

"2" stands for HDPE (high density polyethylene): soy sauce bottle, oil bottle, cleaning, bathing product bottle

HDPE can be heat-resistant 100 °C -120 °C, used for food packaging is generally used to manufacture large-capacity containers, turnover boxes, turnover barrels, etc., with good environmental adaptability.

"3" represents PVC (polyvinyl chloride): medicine bottle, storage bottle

PVC plasticizers without plasticizers are used for pipes, doors and windows, and for small quantities in food and pharmaceutical packaging.

"4" stands for LDPE (low density polyethylene): yogurt bottle, chewing gum bottle, beverage bottle

LDPE is a general-purpose plastic with a low processing temperature. Generally no additives are added. It can be used to make a variety of containers, but the use temperature cannot exceed 80°C.

"5" represents PP (polypropylene): crisper, microwave lunch box

The only plastic box that can be placed in a microwave can be reused after careful cleaning. Need special attention, some microwave lunch boxes, boxes made of PP resin, but the lid is made of PE, because PE can not withstand high temperatures, so can not be put together with the box into the microwave oven. To be on the safe side, remove the lid before placing the container in the microwave oven.

"6" stands for PS (polystyrene): instant noodle box, snack box

PS is good for heat resistance, cold resistance, and impact resistance, but it cannot be put into the microwave oven for heating to avoid release of low-molecular chemicals due to high temperatures. It is not suitable for holding strong acidic substances (such as vinegar, orange juice), and easily decomposes harmful ingredients at high temperatures.

"7" stands for PC (polycarbonate): kettle, cup, pure bucket

Introduction to advertising coffee paper cup

    Advertising coffee paper cups are a form of advertising that is highly accurate and effective. It is conceptually a kind of practical advertisement. Practical advertising is the use of articles with practical functions as advertising carriers for advertising and distribution. The purpose is that while the practicality of the carrier itself is being realized, the advertising that is attached to it can also be demonstrated, and eventually it will reduce the acceptance rejection and evasion brought about by a single advertisement, and realize the flexible dissemination of advertisements. This type of advertisement is particularly effective today when advertisements are flooded and people suffer severe psychological conflict and visual boredom. Therefore, advertising coffee paper cups generally have five major advantages:

    1, practicality, advertising is more easily accepted;

    2. Mandatory, printed on the cup, with coffee paper cups, intentionally or unintentionally always seen;

    3, low consumption, has practical value, ornamental value, can be reused, will not be discarded at will, advertising efficiency rate is higher;

    4, targeted, one-on-one, more direct;

    5, can be monitored, the introduction of delivery receipts, monitoring the entire process, the effect of timely full feedback.
 

    The following are fundamental and systematic. Details ensure the feasibility of coffee paper cup advertising:

    1, coffee paper cups are daily necessary supplies, and very few people refuse to accept;

    2. The coffee paper cups currently on the market are monotonous in color, simple in design, and not aesthetically pleasing. The placement of advertisements will give people a fresh feeling.

    3. In terms of cost control, the overall investment in the design, production, and delivery of advertising coffee paper cups is very obvious compared to other media.

 

    Advertising coffee paper cups are mainly suitable for the following industries
    1. The real estate industry: Basically, each development company and agency company will use advertising coffee paper cups with their own logo, and then each project will also do coffee paper cups for the project, especially before the opening, and the amount is not small;

    2. Decoration and building materials industry: These industries are now generally more profitable and competitive, and they place more emphasis on corporate image.

    3, furniture brands and furniture stores: These are often advertised coffee paper cups;

    4. Advertising company: This kind of company must do it. He was originally advertising.

    5. Herbal Tea and Soybean Milk Stores There are also beverage companies, beauty and hairdressing industries: this industry is profiteering, and such guests have high price demands;

    6, telecommunications, mobile and other enterprise groups: their institutions are large, so a lot;

    7, government departments: They have such office expenses, so find them right.

Disposable paper bowl printing types and prepress issues

At present, advertisers or manufacturers also use paper bowls as an advertising medium.

Designing the pattern on the cup body can give people different drinking moods, and it is also a "symbol" for promoting a certain product. Because the product's trademark, name, manufacturer, distributor, etc., can be designed on the surface of the paper cup. When people drink beverages, they can get acquainted with the information and understand the products. paper bowls provide a platform for people to understand these new products.

Second, compare the printing methods of paper bowls

paper bowls have a variety of printing methods, and different printing methods have different printing characteristics.

Offset printing

Offset printing is the principle of using oil and water repulsion.

Film propaganda paper bowls are oil-resistant and water-resistant. The blank part is hydrophilic and oil-resistant. The images are transferred to the printing materials through a blanket cylinder. The advantages of offset paper bowls are full, vivid, and high definition. No matter whether it is a gradual change or a fine and fine line, it can be clearly displayed, making the appearance of the paper cup more beautiful and attracting the eye of the customer. But offset printing is not suitable for printing edible paper bowls, because offset printing inks are not very environmentally friendly.

2. Silk screen

Screen printing is flexible and flexible due to its flexibility and applicability. It is not only suitable for printing on soft articles such as paper and cloth, but also suitable for printing on hard articles such as glass, ceramics, etc., and is not limited by the surface shape and area of ??the substrate. However, the advantages of screen printing paper bowls cannot be well represented, and screen printing has great restrictions on the reproduction of graphics and texts, and it is difficult to deal with gradual changes and the accuracy of reproduced images.

3. Flexo

Flexo printing is called "green printing" due to the use of water-based inks. Many of the company's product packaging are now developing toward flexo printing.

Because the structure of the flexo printing machine is relatively simple, compared to the large body of the offset printing press and the high cost of materials, the flexo printing machine becomes "thin". In terms of cost, the equipment investment of the flexo printing machine is lower than that of offset printing machines of the same scale, and generally can save as much as 30% to 40%. The small investment in production has attracted the participation of small-scale printing companies. Flexographic printing is not as narrow as the screen printing in the selection of originals, and the rules on color are broader, but they are inferior to offset printing. Flexo printing is the main process currently used for paper cup printing. The print quality of paper bowls depends largely on prepress production. We will now elaborate on the issues that should be noted in prepress production.

The latest Disposable paper cup quality survey shows:

Experts point out that toxic components can easily enter the water

Banks, shops, airplanes, trains, ships, offices, etc. Almost all public places need to drink water and food. There are paper cups in many places. Even in most consumer homes, the original ceramics and glasses are replaced by paper cups, especially for use. Paper cups to entertain guests have become the method approved by most citizens. However, what is the quality of paper tableware? If it fails, will it endanger the health of consumers?

Recently, the International Food Packaging Association conducted investigations on disposable paper cups sold in some large supermarkets in Beijing, Shanghai and Dongguan. Of the 25 paper cup samples sampled, 11 were unqualified. Experts said that the main reason for the lack of cup stiffness is that enterprises use waste paper to reduce costs. They may also use too wet paper or too thin paper, and the direct consequence is that the cup is susceptible to leakage and deformation. , It is easy to burn the user and even cause harmful ingredients to enter the water.

China consumes about 20 billion paper cups each year

It is understood that the International Food Packaging Association had conducted investigations in 2011 on disposable cup products sold in some supermarkets and agricultural wholesale markets in Beijing, Tianjin and Hebei. The survey found that the information on the unlicensed products sold in the farmers' market was unclear, the raw materials of the products were unknown, and even after some products were unpacked, the cups were brightly colored and yellowed; some products were very white in color and were added during the production process. The fluorescent whitening agent with potential carcinogenic effect; disposable cup market mixed, companies implement the industry standard QB2294-2006 "paper cup", and the industry standard does not require ink, some companies use benzene, toluene and other toxic solvents Do ink printing paper cups. China has implemented the market access (QS) system for paper cups, paper bowls, and paper lunch boxes in 2008. Enterprises that produce food contact paper can only produce products that have passed the production license issued by the National Quality and Technical Supervision Department. And sales.

The reporter learned from the official website of the State Administration of Quality Supervision, Inspection and Quarantine that as of the end of July 2012, there were more than 700 manufacturers of paper cups, paper bowls, and paper lunch boxes that had obtained effective production licenses, most of which were paper cups and had more than 600 companies. In addition, many companies do not apply for production licenses still in production, so the actual number of production companies is far greater than the above data. According to relevant investigations, at present, the usage of paper lunch boxes in China is about 1 billion, the amount of paper bowls is about 10 billion, and the amount of paper cups is about 20 billion.

Nearly half of the sample cups and cups are not stiff enough

From May to August 2012, the International Food Packaging Association formed a survey team to investigate disposable cups in Beijing, East China (Shanghai, Zhejiang) and South China (Guangdong). According to the test results, 11 cups of the 25 paper cups under investigation failed the cup body stiffness. Among the 11 unqualified samples, the disqualified rate of paper cups and cups in farmers' markets was significantly higher than that of supermarkets. According to the relevant person in charge of the investigation team, the main reason for the lack of cup stiffness is that enterprises use waste paper to reduce costs. They may also use too wet paper or too thin paper. The direct result is that the cup is too soft to use. Inconvenient, easy to leak and deformation, easy to burn the user, and even harmful components into the water to produce toxic and harmful smell gas.

Paper cup certificate with high phosphor content

During the investigation, the investigation team found that the small labels on the certification labels of paper cups, paper bowls, and other products had very high levels of fluorescent substances, and all exhibited very bright blue fluorescence under ultraviolet light at 365 nm and 254 nm wavelengths. The labels of paper cups and other paper products are generally placed in direct contact with the inner wall of paper cups on the inside of the paper cup. The fluorescent substances on the certificate may enter the human body through the inner wall of the paper cup and contained food or drink, causing harm to the human body and causing cancer risk. .

According to the relevant person in charge of the investigation team, at present, China's national standards do not stipulate the certification of food and beverage tableware and label materials. Therefore, the production company has not strictly selected the certification paper, which is extremely bright. The blue fluorescent paper is likely to be industrial paper, even a low-cost recycled paper.
