Packaging Seal Company is a manufacturer of high performance heavy duty stretch film for heavy, irregular, and sharp-edged pallet loads that need stronger load containment. It is used when ordinary wrap splits at corners, loosens after handling, or allows cargo to shift. With 20-35um thick-gauge options, 80-150 gauge reference choices, high holding force, puncture resistance, and steady recovery, it helps secure bricks, metal parts, timber, drums, hardware, and heavy cartons before warehouse handling or long-distance shipment.
Product Overview
High performance heavy duty stretch film is made for loads that put real pressure on pallet wrap. Its value appears when cargo is heavy, uneven, sharp-edged, or likely to move during forklift handling, road vibration, or longer delivery routes. A 20-35um range is often selected when standard wrap breaks at corners, relaxes after handling, or cannot hold the load tightly enough. Higher thickness can be checked by pallet load testing when metal components, timber ends, brick stacks, drums, or heavy cartons create rough contact points.
When packaging teams compare an advanced heavy duty stretch film with ordinary manual wrap, the difference is usually seen after movement. A low-force wrap may cover the goods, but it may not keep enough pressure on a C-load, an overhanging stack, or a sharp-edged shipment after pre-stretching. A heavy gauge stretch wrap film is the better fit when bottom locking wraps, middle containment layers, and top stabilizing wraps are needed.
Benefits
- High holding force stretch film helps reduce sliding during storage, loading, and transport.
- Thick-gauge construction gives stronger containment on uneven cargo shapes.
- Puncture resistant stretch film lowers cut risk from brick, metal, timber, hardware, and carton edges.
- Tear resistance helps stop a small corner nick from spreading.
- Film recovery helps the wrap stay tight after pre-stretching, handling, and vibration.
- Matched thickness, machine tension, and 150%-300% working stretch help reduce wrap breaks.
When Is a Heavy Gauge Stretch Film the Safer Choice?
A heavy gauge stretch film is safer when standard wrap keeps failing at weak points. This often happens with bricks, metal parts, timber, drums, heavy cartons, or mixed-height products where edges press into the wrap. In these conditions, the material must hold pressure after stretching while resisting puncture, tear growth, and tension loss.
A 20-35um or 80-150 gauge reference range is often selected when ordinary wrap splits, loosens, or allows movement during handling and road vibration. For sharp or rough edges, corner protectors should be used with the wrap. Even a multifunctional heavy duty stretch film works more reliably when cutting stress is reduced around metal edges, timber ends, brick corners, and hard carton stacks.

Applications
- Brick pallets, concrete products, and rough construction materials
- Metal components, pipes, hardware, and machined parts
- Timber, boards, wood strips, and exposed ends
- Drums, pails, and bucket loads that may shift during vibration
- Heavy cartons, mixed-height stacks, and unstable warehouse loads
- Irregular loads that need advanced heavy duty stretch film instead of low-force manual wrap
How Should Holding Force Be Checked Before Transport?
Holding force should be checked as the result of the full wrapping pattern, not guessed from thickness alone. A stable load needs enough wrap tension, film layers, and recovery force at the bottom, middle, and upper zones. Packaging teams should confirm that bottom wraps lock the cargo to the pallet, middle layers resist side movement, and top layers keep loose cartons or irregular items from leaning outward.
The pre-stretch setting should match the load shape. Too little stretch can leave weak containment, while excessive pre-stretch may reduce thickness and increase break risk around sharp edges. A practical check includes corner cuts, loose film tails, pallet overhang, bottom wrap damage, and movement after short handling or vibration testing. Final settings should be confirmed by actual pallet load testing before repeated shipment use.
FAQ
What thickness is recommended for heavy duty stretch film?
For heavy or sharp-edged loads, 20-35um is a common starting range.
Is this product suitable for ordinary light carton pallets?
It is mainly designed for heavy loads, irregular shapes, and cases where standard wrap fails.
How does pre-stretch affect heavy pallet wrapping?
Excessive pre-stretch can reduce thickness and increase break risk around sharp corners.
Should corner protectors be used with this film?
Yes. For sharp metal, brick, timber, or hard carton edges, corner protectors reduce cutting pressure.
