Cross Linked POF Shrink Film is an upgraded polyolefin shrink film processed through irradiation cross-linking technology. This structure significantly enhances the mechanical strength and thermal stability of the film, making it suitable for demanding packaging applications that require higher durability and better sealing performance.
Compared with standard POF shrink film, cross linked shrink film offers improved puncture resistance, tensile strength, and tear resistance, while maintaining excellent shrink clarity and gloss.
It enables packaging of sharp-edged, heavy, or irregular-shaped products with higher protection performance and more stable shrink results in high-speed automatic packaging lines.
This film also helps reduce sealing residue during operation, improving machine efficiency and extending sealing blade life.
Key Advantages
· High puncture resistance for sharp or irregular products
· Stronger tensile and tear resistance for better protection
· Excellent shrink performance with stable sealing behavior
· Low haze and high transparency for premium product display
· Reduced sealing residue, improving machine maintenance cycle
· Enables downgauging (thinner film with same strength) for cost efficiency
· Suitable for high-speed automatic shrink packaging systems
Available Thickness
We offer a full range of thickness options to meet different packaging requirements:10, 12, 13.5, 15, 17, 19, 25, 30micron.
