Enhancing packaging durability and operational efficiency in high-volume production lines requires technically advanced Polyethylene Furanoate film.

Introduction: In high-speed beverage production, collation shrinking is a structural necessity rather than a secondary step. Beverage and Bottle Shrink Film acts as the essential element holding multi-pack units together during Heat Tunnel processing, lifting, and palletizing. Film failure during shrinking or lifting can disrupt production, damage packs, and increase logistics risks. Using shrink film engineered specifically for beverage Heat Tunnel applications ensures uniform pack integrity from filling line to distribution.

Engineered for Stable Heat Shrink Performance
Beverage packs in a Heat Tunnel face concentrated thermal energy and heavy bottle loads. Ordinary films may shrink unevenly, fail to tighten, or tear during lifting. Beverage and Bottle Shrink Film is designed for controlled Heat Shrink activation, contracting evenly around collated units without distortion. Key technical parameters include: COF 0.6–0.8 for smooth handling, tensile strength 120–140 MPa, puncture force ≥18 N (TD direction), and lateral Shrink Ratio 40–70%, ensuring stability throughout tunnel processing and cooling.

Controlled Shrink Ratio for Consistent Collation
Uneven Shrink Ratio causes distorted packs and unstable stacks. Advanced film features optimized molecular orientation to synchronize shrink behavior across the pack surface. Typical Shrink Ratio performance: MD 60–75%, TD 40–70%. This control minimizes Bullseye formation at sleeve openings and maintains uniform pack geometry, supporting automated lifting, conveying, and palletizing operations.

High Holding Force for Heavy Beverage Loads
After Heat Tunnel processing, beverage packs must retain sufficient Holding Force. Inadequate force causes loose packs or tearing during lifting. This film maintains residual tension after cooling, ensuring secure collation under dynamic load. Key performance parameters: Holding Force ≥15 N, puncture resistance ≥18 N (TD direction), preventing failures during lift-and-carry operations.

Mechanical Strength for Reliable Post-Tunnel Handling
Beverage packs are prone to tearing immediately after shrinking. Beverage and Bottle Shrink Film incorporates enhanced puncture and tear resistance to withstand bottle edges and tray contact stress, ensuring reliable performance across the logistics chain and reducing rework.

Practical Specifications for Automated Heat Tunnel Lines
Film is compatible with high-speed Heat Tunnel lines. Balanced thickness 8–40 μm and uniform COF ensure smooth feed through automated systems, minimizing jams and downtime. Consistent Heat Shrink performance and high Holding Force support stable line operation, even for heavy-duty collation scenarios.

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