Aluminum foil bags and composite bags are widely used in the fields of food packaging and electronic packaging. With the development of packaging technology, the product quality, performance, aesthetics and practicability of aluminum foil bags and composite bags have been qualitatively improved. Then, if you compare carefully , What are the obvious differences between aluminum foil bags and composite bags? The following editor will give you a summary and analysis:
Aluminum foil bags and composite bags are widely used in the fields of food packaging and electronic packaging. With the development of packaging technology, the product quality, performance, aesthetics and practicability of aluminum foil bags and composite bags have been qualitatively improved. Then, if you compare carefully , What are the obvious differences between aluminum foil bags and composite bags? The following editor will give you a summary and analysis:
Aluminum foil bags are divided into three-layer composite aluminum foil bags and four-layer composite aluminum foil bags, and then subdivided into ordinary aluminum foil bags and high-temperature steam-resistant aluminum foil bags. The outer material is PET, the center layer is pure aluminum foil, and the inner layer is usually PE or CPP, the center of the four-layer aluminum foil bag is PA material, which can greatly increase the strength and thermal insulation function of the aluminum foil bag. In the supermarket, we can clearly see the shape of the aluminum foil bag. People use three-sided packaging, the bottom layer, and the left and right pieces. This shape is conducive to placing items and has a three-dimensional effect.
The aluminum foil bag has the functions of heat sealing, isolation and light protection. The aluminum foil bag has excellent physical strength and is very suitable for vacuum packaging of food, electronics, medicine and fine export equipment. Most other composite bags are divided into two-layer or three-layer structure. The common outer layer is BOPP and the inner layer is polyethylene. The isolation function of such common composite bags usually cannot meet the high temperature sterilization treatment of food, but can only achieve the normal packaging of goods. The effect is good, but you can print all kinds of beautiful pictures, and the quotation is relatively cheap aluminum foil bags.
Haining Fangsheng Packaging Materials Co., Ltd. has broad prospects for development. After forming an annual production capacity of 1.2 million sets of high-performance industrial packaging bags, the application field has been greatly expanded. Moreover, it also has significant social benefits for the promotion, application and development of high-performance and environmentally friendly packaging materials in my country, and for promoting the upgrading of product structure in related industries.
