First, Plastic Packaging Bag

It has the characteristics of light weight, convenient use, barrier property, permeability, heat resistance, cold resistance, corrosion resistance, and the appearance of color and beauty. Because of its abundant raw materials, low cost and excellent performance, it has been widely used in food packaging, and has gradually replaced traditional packaging materials such as glass, metal and paper, which has brought about a huge change in the appearance of food packaging. It is worth noting that plastic packaging materials have a prominent shortcoming that is not easily degraded, and incineration produces toxic gases. Moreover, plastic packaging materials belong to the shortest period of use in plastic products, generally 1 month to 3 months, the longest one year. Most of the time, most of the urban solid waste enters the garbage disposal system, and some are discarded at will, resulting in "white." Pollution".

Second, Food Paper Bag

In the modern packaging industry system, paper and paper packaging containers occupy a very important position, accounting for 40% to 50% of the total packaging materials. Compared with other materials, it has a series of unique advantages: good processing performance, excellent printing performance, certain mechanical properties, easy compound processing, good lineability, good health and safety, and wide range of raw materials, variety, and low cost. It is easy to form large-scale production. The paper packaging container is light in weight, good in cushioning, widely used, and waste can be recycled and used without white pollution. With the enhancement of environmental awareness and the actual needs of life, the development of plant fiber snack boxes and the development of natural green packaging materials will be the future trend of paper packaging materials.

Third, metal packaging materials

The excellent performance of metal packaging materials includes: high barrier property, excellent mechanical properties, good processability of container molding, good high and low temperature resistance, thermal conductivity and thermal shock resistance, good surface decoration and easy packaging waste. Recycling treatment. Canned foods, as well as some liquid, paste, powder or high-grade foods. Commonly used metal packaging materials are tinplate and aluminum, which are widely used in the manufacture of food and beverage packaging cans.
