Woven bags, also known as snake skin bags. Is a kind of plastic bag, used for packaging, its raw materials are generally polyethylene, polypropylene and other various chemical plastic materials. Woven density refers to 100mm × 100mm woven fabric, the number of roots of warp and weft yarn. Foreign production of the main raw material for polyethylene (PE), domestic production is mainly polypropylene (PP), is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the minimum operating temperature can reach -70 ~ -100 ℃), good chemical stability, can resist the erosion of most acids and bases (not resistant to acids with oxidizing properties), insoluble in general solvents at room temperature, small water absorption, excellent electrical insulation properties; but polyethylene is sensitive to environmental stress (chemical and mechanical effects), poor heat aging resistance. The properties of polyethylene vary from species to species, depending mainly on the molecular structure and density. Different production methods can be used to obtain products with different densities (0.91~0.96g/cm3).
We are committed to creating personalized packaging exclusively for enterprises, highlighting the perfect image of enterprises. According to the core needs of enterprises, we analyze the size, color, personality, occasion and budget of the bag, and create a tailor-made packaging culture for enterprises to realize the corporate value and brand culture communication.
