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.
