Generally, PE inner membrane bag is used as the inner lining of woven bag, which plays the role of moisture-proof, moisture-proof and leak-proof for the product, and can also be used independently (storing clothes, quilts, shoes, plush toys, etc.). Next, SHANDONG DAPOLY GROUP will distinguish the high bottom pressure of PE inner membrane bag from the production process, material description and use of PE inner membrane bag!
1, Introduction to production process of PE inner membrane bag
1. High-pressure PE inner membrane bag is polymerized with polymerized ethylene as raw material, organic peroxide as medium, and 130-280Mpa ultra-high pressure and high temperature process of about 300 ºC in the tubular reactor cargo tank reactor.
2. Low-pressure PE inner membrane bag is made of high-purity polyethylene as raw material, polypropylene or 1-butene as comonomer, alkane as solvent, solution polymerization at a certain temperature (65-85) and pressure (0.1-0.7Mpa) in the presence of highly active catalyst, separation, drying, mixing and granulation.
2, Material of high and low pressure PE inner membrane bag
1. Low-density high-pressure polyethylene feels soft, white and transparent, but the transparency is general, and the combustion identification (the burning flame is yellow and blue, smokeless when burning, with the smell of paraffin, melting and dripping, easy to draw)
2. HDPE is a kind of thermoplastic resin with high crystallinity and non-polarity. The appearance of the original high-density polyethylene is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most domestic and industrial chemicals. Some kinds of chemicals will produce chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance, and can be used for packaging purposes. High density polyethylene has good electrical properties, especially high dielectric strength of insulation, which makes it very suitable for wires and cables. Medium to high molecular weight grade has excellent impact resistance, even at room temperature and low temperature of - 40F.
Polymerization pressure: high pressure, medium pressure and low pressure;
Polymerization implementation methods: slurry method, solution method, gas phase method;
Product density size: high density, medium density, low density, linear low density;
Product molecular weight: low molecular weight, ordinary molecular weight, ultra-high molecular weight.
Polyethylene is odorless, non-toxic, wax-like, with excellent low temperature resistance (the minimum service temperature can reach - 70~- 100 ºC), good chemical stability, resistant to most acids and alkalis (not resistant to acids with oxidizing properties), insoluble in general solvents at room temperature, low water absorption, and excellent electrical insulation; However, polyethylene is very sensitive to environmental stress (chemical and mechanical action) and has poor thermal aging resistance. The properties of polyethylene vary from variety to variety, mainly depending on the molecular structure and density.
3, Purpose of high and low pressure PE inner membrane bag:
High pressure polyethylene: more than half of it is used for film products, followed by pipes, injection molding products, wire wrapping, etc.
Medium and low pressure polyethylene: mainly injection molding products and hollow products.
Ultra-high pressure polyethylene: due to its excellent comprehensive properties, it can be used as engineering plastics.
High-pressure PE inner membrane bag is applicable to extrusion, blow molding, injection, vacuum, molding, coating and rotary molding and other processing methods to manufacture food security film, agricultural film industrial light packaging film, general transparent film, thin film, wire, cable sheath, pipe, chemical container, synthetic paper, foam products, etc.
Low-pressure PE inner membrane bags are mainly used for blow molding, manufacturing various bottles, cans and barrel packaging containers for injection molding, manufacturing pots, baskets, baskets, turnover boxes and industrial machinery parts, and for extrusion molding and manufacturing various pipes, films, woven bags, narrow filaments, monofilaments, etc.
SHANDONG DAPOLY GROUP specializes in producing high and low pressure PE inner membrane bags. At the same time, our factory also specializes in producing food-grade PE inner membrane bags.
