Packaging film X5

shrinkpolyolefinfor the cosmetics industry

Product Overview
X5 is a POF heat shrinkable film engineered to address common shrinkage challenges in industrial packaging. It is designed to start shrinking at low temperatures (around 70°C), offers high shrink speed, strong heat-seal performance and more than 70% free shrink capability for a tight packaging effect even under adverse conditions. The film provides hot-slip properties to prevent adhesion or abrasion on folded boxes or flat-sheet products after shrink packaging. Compared with other non cross-linked polyolefin films, X5 exhibits a wide shrink-temperature window and relatively low shrinkage force.

Key Features

• Compatible with standard shrink-packaging machines
• Low-temperature shrink start (designed to begin shrinking at ≈70°C)
• High shrink speed with good seal strength
• Free shrink >70% for strong packaging effect
• Hot-slip surface to avoid adhesion or surface abrasion on packed items
• Wide shrink-temperature range and lower shrinkage force vs. other non-cross-linked polyolefin films

Available Thicknesses
9 μm, 11 μm, 14 μm, 19 μm.
