Eco-friendly PE shrink film offers strong sealing, high clarity, and recyclable performance for sustainable packaging.

Beverage Heat Tunnel Challenges in Collation Shrinking

Beverage collation shrink processes expose film to continuous heat, high-speed Tunnel operation, and significant unit load weight. When material design does not match these conditions, structural problems appear immediately after Heat Shrink.

Shrink not tight due to insufficient post-cooling Holding Force

Shrink not flat caused by unbalanced Shrink Ratio in MD/TD

Film breakage during lifting and transfer under heavy load

These are functional failures, not visual defects, and they directly affect downstream logistics.

Controlled Shrink Ratio for Stable Beverage Collation

This PE shrink film is engineered with controlled molecular orientation to deliver predictable Heat Shrink behavior in beverage Tunnel environments.

Shrink Ratio (MD/TD): MD 60–65%, TD 10–15%

Uniform shrink progression through the Heat Tunnel

Reduced internal stress to maintain flat and stable collation packs

Balanced Shrink Ratio prevents corner pull-in, surface distortion, and uneven tension across beverage bundles.

Bullseye Quality and Holding Force After Heat Shrink

In beverage collation, Bullseye formation reflects sleeve stability and load containment performance.

Clean and centered Bullseye at sleeve ends

Consistent closure without edge curling after shrinking

Holding Force: ≥18 kg for standard bottled beverage collation

High Holding Force ensures that finished packs remain intact during lifting, conveying, and palletizing.

Mechanical Strength for Heavy Beverage Loads

Beyond shrink appearance, mechanical durability defines real performance in beverage logistics.

Puncture Force: ≥12 N to resist bottle edge and corner impact

Stable seal integrity throughout the Heat Tunnel process

Reduced risk of breakage when packs are lifted or transferred

This strength profile directly addresses the critical pain point of film failure during handling.

Line Compatibility in Beverage Shrink Tunnel Operations

This PE shrink film is optimized specifically for beverage collation lines operating with Heat Tunnel shrinking.

Coefficient of Friction (COF): 0.25–0.35 for stable conveying

Consistent thickness control for uniform Tunnel exposure

Suitable for high-speed beverage collation without film slippage

Operational stability minimizes downtime and improves collation consistency.

A Dedicated PE Shrink Film for Beverage Collation Systems

This is not a general-purpose shrink material. By enforcing strict product line isolation and focusing exclusively on beverage Heat Tunnel collation, this PE shrink film delivers reliable Heat Shrink performance, controlled Shrink Ratio, strong Bullseye formation, and dependable Holding Force. For beverage factories handling heavy collation loads, correct shrink film selection is a critical engineering decision that directly influences production stability and shipment integrity.
