PE: polyethylene is probably the polymer used most in daily life, which can make grocery bags, shampoo bottles, toys, etc.
LDPE: is a tough, slightly translucent material, with excellent chemical resistance, particularly to acids, alkalis and inorganic solution, but is sensitive to hydrocarbons and halogenated hydrocarbons and to oils and greases.
HDPE: possesses a much more linear structure than LDPE and has up to 90 percent crystallinity compared to LDPE. HDPE film is stiffer and harder than LDPE.
PP: polypropylene is a vinyl polymer and is similar to polyethylene, which has a lower density and a higher softening point than the polyethylenes, low water vapor transmission, medium gas permeability, good resistance to greases and chemicals, good abrasion resistance, as well as good gloss and high clarity, the latter two factors making it ideal for reverse printing.
OPP: is not considered to be a gas barrier film and often have a stiff feel and tend to crinkle audibly.
PET: has excellent physical features, such as high strength, low stretch, good barrier for gas and aromas, good printing and lamination ability, high temperature resistance.
BOPP/PE packaging film: has good moisture, frozen resistance, good sealable property, can be used for instant noodles, frozen food, washing powder, biscuits, chocolate, powder packaging.
BOPP/CPP packaging film: has good moisture, oil barrier, good transparency property, can be used for instant noodles, cookies, candy, dry light food packaging.
PET/VMPET/CPP packaging film: has good moisture, oxygen, gas resistance; can be used for milk powder, coffee, medical, packaging, powder packaging.
NY/PE packaging film: has good oil, oxygen, heat impact resistance, vacuum packaging; can be used for meat processed, ham, chicken, sausage, soy sauce, noodle soup, rick cakes, water-bearing materials packaging.
