1. Composite film: according to the sealing temperature (condition is o. 18 mpa, 1 s, lN / 15 mm or higher) can be divided into: general composite membrane (< 140 ℃), low
Warm sealing composite membrane (< 115 ℃), ultra-low temperature sealing compound membrane (< 100 ℃).General and BOPP film or BOPET film composite after printing
BOPP/CPP (or BOPET/CPP) membrane on the second floor, used in dry cloth, food, puffed food packaging.The developing direction is:

Composite bag
2. High transparency, high opening performance is good, smooth (after curing COF package < 0.2), low heat sealing temperature, to adapt the demand of high speed bag making and packaging.
