Stop Overpaying for the Wrong Stretch Film
Many procurement managers buy stretch film based purely on "price per roll." This is a massive mistake. The true metric is "cost per wrapped pallet." Buying a cheap, low-micron film often means warehouse staff must wrap a pallet 10 times instead of 4, wasting labor and actually increasing the plastic cost per pallet.
Cast vs. Blown Stretch Film
Understanding the manufacturing process is key to selecting the right film:
- Cast Stretch Film: Manufactured by extruding molten resin over chilled rollers. It has excellent clarity, unrolls quietly, and has high tear resistance. Ideal for 90% of warehouse applications.
- Blown Stretch Film: Manufactured by blowing air into a bubble of resin. It is tougher, louder when unrolled, and offers higher puncture resistance for irregular loads (e.g., bricks, sharp machinery).
Machine Grade vs. Hand Grade
| Specification | Hand Film | Machine Film |
|---|---|---|
| Standard Width | 400mm - 500mm | 500mm - 1000mm |
| Stretch Capacity | 50% - 100% | 200% - 300% |
| Core Size | Extended core optional | Standard 3-inch flush core |
The Pre-Stretch Advantage
If your warehouse uses semi-automatic wrappers, ensure your machine has a "pre-stretch" carriage. This mechanism stretches the film before it hits the pallet, maximizing the yield of a roll and increasing the containment force.
