Introduction: The increasing demand for high-speed beverage production has elevated collation shrinking from a secondary task to a critical structural process. For beverage manufacturers, Shrink Film for Automatic Packing is the essential element that secures bottles and cans together during Heat Tunnel shrinking, lifting, and palletizing. Failure during shrinking or lifting can disrupt production, damage packs, and increase logistics risks. Films engineered for automatic packing in beverage Heat Tunnel systems ensure consistent pack integrity from filling line to distribution.

 

Engineered for Reliable Heat Shrink Performance Beverage packs moving through a Heat Tunnel face concentrated thermal exposure and heavy mechanical loads. Standard films often fail to achieve uniform shrinkage or sufficient tightness, causing skewed or loose packs. Shrink Film for Automatic Packing is designed for controlled Heat Shrink activation, delivering even contraction around collated units without distortion. Key technical parameters include COF 0.65–0.8 for smooth automated handling, tensile strength MD ≥28 N/mm², TD ≥20 N/mm², and thickness 50–100 μm, ensuring consistent shrink and pack stability.

 

Controlled Shrink Ratio for Uniform Collation Uneven Shrink Ratio is a primary cause of distorted beverage packs and unstable stacks. Advanced films feature optimized molecular orientation to synchronize shrink behavior across the pack surface. Typical Shrink Ratio performance includes MD 55–65% and TD 60–70%, reducing Bullseye formation at sleeve openings and maintaining consistent pack geometry, supporting smooth downstream lifting, conveying, and palletizing operations.

 

High Holding Force for Heavy Beverage Loads After Heat Tunnel shrinking, beverage packs must retain sufficient Holding Force to withstand automated lifting and palletizing. Inadequate holding can lead to loose packs or tearing. The film maintains residual tension after cooling, providing Holding Force ≥15 N and puncture resistance ≥18 N (TD direction), ensuring secure collation of bottles under dynamic load.

 

Mechanical Strength for Post-Tunnel Handling Heavy beverage packs can tear when lifted immediately after shrinking. Shrink Film for Automatic Packing incorporates enhanced puncture and tear resistance to withstand edges and tray contact, protecting product integrity and reducing rework throughout the logistics chain.

Practical Specifications for Automated Heat Tunnel Lines The film is optimized for high-speed automatic lines. Controlled COF, uniform thickness, and consistent Heat Shrink behavior minimize jams and downtime, ensuring stable line operation even in heavy-duty collation scenarios.

 

Conclusion: In beverage production, collation shrinking is a structural requirement. Using inappropriate film can result in loose packs, uneven shrink, and failure during lifting. Investing in Shrink Film for Automatic Packing with controlled Shrink Ratio, reliable Heat Shrink behavior, sufficient Holding Force, and proven mechanical strength ensures consistent pack integrity from Heat Tunnel exit to palletizing.
