Packaging film ZCR03

for packagingshrinkpolymer

Overview
This is a kind of polyolefin cross-linked heat shrinkable film containing 31% post-consumer recycled material. In production and properties ZCR03 is basically the same as ZDF03, offering high shrinkage (nearly 80%), good mechanical properties, high heat sealing strength, good toughness, and outstanding heat and cold resistance. ZCR03 film has passed the GRS4.0 certification.

Key features

• Material: Cross-linked polyolefin shrink film with 31% post-consumer recycled polyethylene (RM0193)
• High free shrink (approaching 80% under certain conditions)
• Good mechanical strength and toughness
• High heat-seal strength (hot-wire seal)
• Good heat and cold resistance
• Available thicknesses: 15 micron, 19 micron, 25 micron, 30 micron
