Plastic bags are mainly divided into two categories, one is not compounded, and the other is compounded.

Materials without composites generally use HDPE, LDPE, OPP, CPP, shrink film, etc.

HDPE and LDPE are generally used in clothing packaging bags, and are also widely used in convenience bags, shopping bags, handbags, vest bags, etc. OPP and CPP are used for inner packaging bags of clothing.

Clothing bags are for the convenience of guests to carry. The inner packaging bag of clothing is mainly used to prevent moisture and dirt before the clothes are unpacked.

The main material of the vest bag is HDPE, which is the shopping bag we often see in supermarkets, and it is made of HDPE material.

OPP material is also used for bread packaging, because its transparency is better, which can better improve the grade of the product.

OPP and CPP materials are also widely used in the packaging of small commodities.

Composite materials are generally divided into double composite and triple composite.

Double composites include OPP+CPP(PE), PET+CPP(PE), PA+CPP(PE) [mainly used for vacuum packaging such as cooked food]

The three-composite ones are PET+OPP+CPP(PE) aluminum foil+PET+CPP(PE) [this material has a fresh-keeping effect].

Among them, PET is also divided into aluminum-plated and transparent. There are also many materials here, and it is not easy to explain them one by one. The specific material for the packaging depends on the product being packaged. There are also various styles of bags. Plastic packaging can better meet customers' individual needs, and can improve the use and appearance of products.

The composite application is very wide, and can be used in various daily necessities and food packaging. Such as pastries, candies, roasted seeds and nuts, biscuits, milk powder,

Tea, shirts, clothing, needle cotton products, chemical fiber products, etc.
