5 new functions of composite paper can!

Composite paper cans can be used to hold various foods, such as tea, sugar, salt, cereal, coffee and various solid drinks, as well as health food, oil food and frozen concentrated food with high moisture-proof requirements. With the development of composite paper cans, Jiayi packaging is constantly improving its functions. On the basis of packaging functions, the following five new functions are launched, such as sterilization, anti-corrosion, fresh preservation and moisture prevention:

1. Sterilization and anti-corrosion: paper cans, especially food paper cans, rice flour paper cans, milk powder paper cans and tea paper cans, need sterilization and anti-corrosion functions. Sterilized or anti-corrosion raw materials are injected into the pulp, so that the paper packaging can prevent bacterial invasion and delay food deterioration.

2. Preservation: many food paper cans are required to have preservation function. After chemical treatment and selective resin addition, the paper can preserve the freshness of baked food.



3. Moisture proof function of paper cans: spray waterproof material on the surface of paper cans to form a film attached to one or both sides of the paper, so that the food packaging paper has moisture proof performance. This paper has good printing, folding, bonding and other characteristics, and can be used like ordinary paper.

4. Visible: now there are paper cans that can be seen. After special surface treatment, after the surface of the paper is wetted, the paper changes from opaque to transparent. Consumers can see the food in the bag without unpacking, and can play a role in avoiding light in a dry state.

5. Temperature sensing: many paper cans are required to have temperature sensing function. Artificial fibers that can change color with temperature change are added to the pulp to indicate the ambient temperature according to the color change of packaging paper, and the food can be effectively preserved according to the color change of food packaging bag.

Composite paper cans are made of various paper, food plastic film, food aluminum foil or Tetra Pak packaging materials. A cylindrical rigid packaging container with a sealable end cap and an outer trademark is manufactured by high-temperature heating and winding industry. Compared with domestic traditional paper, plastic, glass, metal and packaging products, it has the characteristics of light weight, good stiffness, long service life, strong air tightness, oil and water resistance, fresh-keeping and moisture-proof, beautiful decoration, convenient use, not easy to be damaged, affordable price and so on.

The performance of the composite paper can is basically similar to that of the tinplate can, and can be comparable to that of the tinplate can in terms of strength, air tightness and beautiful appearance. In particular, the corrosion resistance of the inner wall is difficult for the iron can head cylinder to achieve. Because it can select various lining materials to meet the needs of packaging performance of different interior items. Colleagues, the container waste treatment is simpler than the iron earpiece, and it is also easy to recycle. The price of composite paper cans is 15-25% lower than that of tinplate cans of the same specification, and can generally save 60-65% tinplate materials.

Therefore, the large-scale production and use of composite paper cans instead of tinplate cans and other traditional packaging products not only meet the packaging and consumption needs of the growing majority of users, but also reduce the packaging costs for users, save a lot of foreign exchange for imported tinplate for the country, and ease the tight supply of tinplate in China, Then we can obtain good economic benefits and comprehensive social benefits.



The above is an introduction to the five new functions of the composite paper can. The composite paper can enjoys a high reputation in the packaging industry, and its application is extended to the packaging of perishable products and even fast food. In addition to the protection of the packaged items, the paper can has a more beautiful appearance and is easy to carry.
