Plastic woven Glossary: ??woven mainly in terms of: Plastic bags are polypropylene (English pp) as the main raw material, extruded, drawn into flat yarn, and then weaving, the preparation, the bag is made. Parameters commonly woven density is 36 × 36 根 / 10cm2, 40 × 40 根 / 10cm2, 48 × 48 根 / 10cm2. 1. weave density tolerances. Weave density tolerance is the ratio of a given standard weave density or reduce the number of multiple flat yarn. Screen printing ink thickness, print rich texture, dimension, this is other printing method can not be compared. Not only can screen printing monochrome printing, also can be cased and screen color printing. ③ light and strong, bright color screen printing have been printed since the characteristics, so it can use a variety of inks and coatings, not only can the slurry, bonding agents and pigments can also be used coarser pigment particles. In addition, screen printing ink deployment method is simple, for example, can be put directly into the light pigment ink formulations, this is another major feature of screen printing. Xiong Xin Yu plastic bag factory specializing warm for you popularize knowledge of the industry: foreign main raw material for the production of polyethylene (PE), mainly for the domestic production of polypropylene (PP) plastic bags, is a thermoplastic obtained by polymerization of ethylene resin. In the industry, but also copolymers of ethylene with minor amounts of α- olefins. Polyethylene plastic film bags odorless, non-toxic, feel like wax-lined plastic bags, has excellent low temperature properties (lowest temperature up to -70 ~ -100 ℃), good chemical stability, resistance to most acid-base erosion (impatience with oxidation properties of acid), room temperature, soluble in common solvents, water absorption of small plastic bags of good companies, electrical insulation properties; but polyethylene for environmental stress (chemical and mechanical action) is very sensitive , heat aging poor oxidative dyeing signs of melamine and aluminum oxide color printing plate is no different. 6. The printing plate aluminum oxide aluminum oxide signs, panels after oxidation, the surface will be accompanied by a layer of oxide film is hard and smooth surface. By conventional screen printing ink adhesion is poor, which is the most important issue.
