OPP/LDPE composite bag (pet food packaging bag)
OPP/LDPE composite bag is also called BOPP/PE or BOPP/CPP structure. BOPP is a thin film with good physical stability, mechanical strength and air tightness, high transparency and gloss, high moisture-proof barrier, tough and wear-resistant.The main disadvantage of bidirectional tensile polypropylene film is poor thermal sealing, so the outer film used as composite film is an important base material for plastic composite soft packaging.
LDPE (low density polyethylene) is milky white bead - shaped granule.Non - toxic, tasteless, odorless, matt surface.The density is 0.916~0.930g/cm3.Nature is soft, has good extensibility, electrical insulation, chemical stability, processability and low temperature resistance, resistant to - 20 ℃) for thermoplastic processing a variety of molding process, but the mechanical strength, humidity, gas and solvent resistance is poorer, and the characteristics of BOPP just complementary do lining composite film;Can be packed rare food, dry food, impregnated food.
