Understanding PE Shrink Wrap: The Versatile Solution for Packaging Needs
Release Date: Dec 16,2025
Introduction:
High-speed beverage production requires reliable collation shrinking as a structural necessity. PE shrink film is the critical element that holds multi-pack units together during Heat Tunnel processing, lifting, and palletizing. Failure during shrinking or lifting can disrupt production, damage packs, and increase logistics risks. Ruida’s PE Shrink Film is engineered specifically for beverage Heat Tunnel systems to ensure consistent pack integrity from filling line to distribution.
1. Engineered for Reliable Heat Shrink Performance
Beverage packs in a Heat Tunnel endure concentrated heat and heavy bottle loads. Ordinary films may shrink unevenly, leading to skewed packs or tears. PE shrink film delivers controlled Heat Shrink activation, contracting evenly around collated units without distortion. Key technical parameters include:
Shrink Ratio (MD/TD)
COF for smooth handling
This ensures consistent tightening and dimensional stability throughout tunnel processing and cooling.
2. High Holding Force for Heavy Beverage Loads
After Heat Tunnel processing, beverage packs must retain sufficient Holding Force. Inadequate tension causes loose packs or sudden tearing during lifting. PE shrink film maintains residual tension after cooling, securing bottles under dynamic load. Key performance parameters include:
Holding Force ≥15 N
Puncture Force ≥18 N (TD direction)
This prevents failures during lift-and-carry operations.
3. Reliable Post-Tunnel Handling
Heavy beverage packs can tear immediately after shrinking. PE shrink film’s enhanced puncture and tear resistance withstands stress from bottle edges and tray contact points, reducing rework and ensuring product integrity.
Conclusion:
Using unsuitable shrink film may result in loose packs, uneven shrink, and failures during lifting. Investing in PE shrink film with controlled Shrink Ratio, sufficient Holding Force, and proven mechanical strength ensures consistent pack integrity from Heat Tunnel exit to palletizing.
