　　First of all, if it is divided according to the packaging function required by the product, it can be divided into three-layer packaging in composite packaging bags and special packaging bags. Among them, the three-layer packaging in the composite packaging bag is generally BOPP/PET/PE, BOPP/WMPET/PE, BOPP/PE, which can be used for most packaging, such as dried fruit packaging bags, condiment packaging bags, candy packaging bags, vacuum roast duck packaging Most products such as bags can use this type of packaging material.

　　③Chemical product packaging bags: including pesticide packaging bags, chemical corrosive product packaging bags, mostly PET/BOPA/AL/CPP, but because it is compounded with anti-corrosion glue, CPP still has a certain air permeability, long-term use, If the corrosive liquid contacts the anti-corrosion glue through the CPP, it may cause delamination.

　　And if it is classified according to bag shape, the packaging bags currently in use in the market are also divided into many types according to different needs, such as self-supporting packaging bags, self-supporting zipper bags, three-side sealing zipper bags, self-supporting nozzle bags, special-shaped bags, ordinary three-dimensional bags. Side seal, back seal pillow bag, five side seal, middle seal bag, etc., they each have their own characteristics, which can better protect the goods.
