In modern beverage factories, PE shrink film used for heavy-duty collation is a load-bearing functional material rather than a simple packaging consumable.

 

Performance Challenges in Beverage Heat Shrink Lines

Inside a beverage Heat Tunnel, shrink film is exposed to continuous heat, high throughput, and heavy unit loads. Improper material design leads to visible and mechanical failures after Heat Shrink.

Shrink not tight: insufficient Holding Force after cooling

Shrink not flat: unbalanced Shrink Ratio causing distortion

Breakage when lifted: low puncture or tear resistance under load

These issues are not cosmetic defects but structural failures affecting transport and pallet stability.

Controlled Shrink Ratio for Flat and Stable Collation

Heavy-duty collation requires predictable and directional shrinking behavior. This PE shrink film is engineered with controlled molecular orientation to maintain balance between machine and transverse directions.

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

Stable Heat Shrink response across standard beverage tunnel temperatures

Uniform shrink progression to avoid corner pull-in and surface wrinkling

Balanced Shrink Ratio ensures packs shrink tight without warping or uneven tension distribution.

Bullseye Formation and Holding Force Under Load

For beverage bundles, Bullseye quality directly reflects sleeve stability and load containment.

Clean and centered Bullseye at sleeve ends

Consistent sleeve closure without edge curling

Holding Force: ≥18 kg for typical bottled beverage collation

High Holding Force allows finished packs to be lifted, conveyed, and palletized without film rupture or pack separation.

Mechanical Strength for Heavy Beverage Loads

Beyond shrink appearance, mechanical durability defines real-world performance.

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

Stable seal integrity throughout Heat Tunnel processing

Designed to withstand dynamic stress during handling and transport

This strength profile prevents breakage during lifting, one of the most critical pain points in beverage logistics.

Line Compatibility and Operational Parameters

This PE shrink film is optimized for industrial beverage lines, not mixed-use operations.

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

Consistent thickness control for stable tunnel performance

Suitable for high-speed Heat Tunnel systems without film flutter or slippage

Operational stability reduces downtime and ensures consistent output quality.

A Dedicated Solution for Beverage Heat Shrink Systems

This is not a general-purpose shrink material. By enforcing strict product line separation and focusing exclusively on beverage Heat Tunnel applications, this PE shrink film delivers reliable shrinking behavior, strong Holding Force, and mechanical durability. For factories handling heavy beverage loads, correct film selection is a critical engineering decision that directly impacts line efficiency and shipment integrity.
