Plastic packaging bags are packaging bags made of plastic, which have been widely used in daily life and industrial production, especially to bring great convenience to people’s lives. So what are the classifications of plastic packaging bags? What are the specific uses in production and life? Take a look:
Plastic packaging bags can be divided into PE, PP, EVA, PVA, CPP, OPP, compound bags, co-extrusion bags, etc.
PE plastic packaging bag
Features: excellent low temperature resistance, good chemical stability, resistance to most acid and alkali erosion;
Uses: Mainly used to manufacture containers, pipes, films, monofilaments, wires and cables, daily necessities, etc., and can be used as high-frequency insulating materials for TVs, radars, etc.
PP plastic packaging bag
Features: transparent color, good quality, good toughness, stronger and not allowed to be scratched;
Uses: used for packaging in various industries such as stationery, electronics, hardware products, etc.
EVA plastic packaging bag
Features: flexibility, resistance to environmental stress cracking, good weather resistance;
Uses: It is widely used in functional shed film, foam shoe material, packaging mold, hot melt adhesive, wire and cable and toys and other fields.
PVA plastic packaging bag
Features: good compactness, high crystallinity, strong adhesion, oil resistance, solvent resistance, wear resistance, and good gas barrier properties;
Uses: It can be used for packaging of oil crops, small miscellaneous grains, dried seafood, precious Chinese herbal medicines, tobacco, etc. It can be used in conjunction with scavengers or vacuuming to keep the quality and freshness of anti-mildew, anti-moth-eaten, and anti-fading.
CPP plastic bags
Features: high stiffness, excellent moisture and odor barrier properties;
Uses: It can be used in clothing, knitwear and flower packaging bags; it can also be used in hot filling, retort bags and aseptic packaging.
OPP plastic bags
Features: high transparency, good sealing and strong anti-counterfeiting;
Uses: Widely used in stationery, cosmetics, clothing, food, printing, paper and other industries.
Compound bag
Features: good stiffness, moisture-proof, oxygen barrier, shading;
Uses: Suitable for vacuum packaging or general packaging of chemical, pharmaceutical, food, electronic products, tea, precision instruments and national defense cutting-edge products.
co-extrusion bag
Features: good tensile properties, good surface brightness;
Uses: Mainly used in pure milk bags, express bags, metal protective films, etc.
Plastic packaging bags can be divided into: plastic woven bags and plastic film bags according to different product structures and uses
plastic woven bag
Features: light weight, high strength, corrosion resistance;
Uses: It is widely used as a packaging material for fertilizers, chemical products and other items.
plastic film bag
Features: light and transparent, moisture-proof and oxygen-resistant, good air tightness, toughness and folding resistance, smooth surface;
Uses: It can be used in various industries and products such as vegetable packaging, agriculture, medicine, feed packaging, chemical raw material packaging, etc.
