Short for common plastic film and the advantages and disadvantages

Plastic raw material classification is more, here are some commonly used film and referred to as: the name of the film or film PE polyethylene blow of polyethylene plastic film CPE undrawn stretch film blowing plastic film PP polypropylene plastic film CPP stretch film plastic film of polypropylene undrawn OPP plastic film of polypropylene single tensile BOPP plastic film of polypropylene two-way stretch ZBOPP pearl of polypropylene two-way stretch plastic film XBOPP extinction of polypropylene two-way stretch plastic film BOPET polyester two-way stretch plastic film PA nylon blowing or co-extrusion plastic film BOPA nylon two-way stretch plastic film KBOPA coated polyvinylidene chloride of high separation nylon two-way stretch plastic PVC PVC film or PVC heat shrinkable plastic film OPVC and unidirectional tensile kink film or tear film PVA polyvinyl plastic film PVDC polyvinylidene chloride high barrier plastic film PT cellophane plastic film EVA plastic film vinyl acetate DAl crossing vacuum steaming aluminum plastic film commonly used plastic film each have advantages and disadvantages, make a simple form to do a show, as follows: BOPP transparent and high gloss film advantages disadvantages process: Excellent printing ink and coating adhesion; Excellent water and grease barrier property; Low electric resistance heat sealing and two-way stretch CPP good heat sealing; Can be used as a composite material basement membrane; Degree of tearing resistance is strong; Good cooking resistance low temperatures easily brittle stretch BOPET tensile strength; Good antistatic property; Good transparency; Rigid, high hardness and toughness; High and low temperature resistance; The chemical resistance; Good air tightness and sweet poor heat sealing; Systolic small two-way stretch BOPA good resistance to burst; Resistance to impact. The tensile strength and penetration resistance is outstanding; A fine flexibility; Temperature tolerance range is extensive; Strong resistance to oil and gas permeability easy water absorption; Poor stability of two-way stretch PE moisture resistance, moisture permeability small; PE membrane permeability is larger, and with the increase of the density, its permeability is falling; Low density polyethylene film transparency and good heat sealing; Can waterproof, moistureproof, High density polyethylene film heat resistance and mechanical strength of the poor is better than low density polyethylene film stiffness; Low tensile strength, tensile elongation is big, easy to knit; Heat is easy to deformation, tinted difficulties; The higher the density the less transparency; The tear resistance is poor; Barrier property of smaller blow molding, stretch, stretch film, low foaming
