Classification and characteristics of plastic packaging bags have?

Plastic bags according to the product structure and use different can be divided into: CPP non-toxic advantage in plastic woven bag with a plastic film bag, composite, transparency is better than PE, hardness is a bit poor. Texture is soft, the transparency of PP, PE softness. PP hardness after OPP, stretching, Two-way stretch) Back into a triangle, bottom sealing or edge-sealing PE with formalin, transparency is a bit poor PVA soft texture, good transparency, it is a kind of new environmental protection material, the water melts, raw materials are imported from Japan, expensive, has been widely applied in foreign countries and OPP good transparency, hardness strong compound bag sealing strength, printing, printing ink will not fall off co-extrusion bag good transparency, texture soft, can press printing woven bag plastic woven bag of main materials for the pp bag, PE bag; According to the seam sewing method is divided into bottom bag, hemming bottom bag. Widely used in fertilizer, chemical products and other items of a packaging material. Its production process is the use of plastic raw materials mainly by the squeeze film, cutting, uniaxial tensile as flat wire, through the warp/weft knitting products, commonly known as woven bag features: light weight, high strength, corrosion resistance and other characteristics, after joining plastic film inner lining, is moistureproof prevent wet; Light bag weight in 2. Below 5 kg, medium-sized bag weight in 25 Heavy bags, 50 kg load - 50 100 kg of raw materials for plastic film bag of polyethylene film bag. Plastic bags do bring the convenience to our life, but the same convenience bring lasting harm. According to production raw material classification: high pressure polyethylene plastic bags, low pressure polyethylene plastic bags, pp bags, PVC bags, etc. According to the shape classification: vest bag, straight tube bag. Sealing bag, glue bag, special-shaped bag, etc. Features: light bag weight above 1 kg; Medium-sized bag weight 1 - 10公斤; 10 - load heavy bag 30kg； More than 1000 kg bag container load.
