📦 Stretch Film (Stretch Wrap)
Stretch film is a highly stretchable plastic film used to wrap and secure products, especially on pallets, without the use of heat. It clings tightly to itself due to elastic recovery, keeping goods stable during storage and transportation.
🔍 What Is Stretch Film Made Of?
Most stretch film is made from:
LLDPE (Linear Low-Density Polyethylene) – the most common material
Produced using:
Cast extrusion (clear, quiet unwind)
Blown extrusion (stronger, more puncture-resistant)
🎯 Key Features
✅ High stretchability (can stretch 100–300%+)
✅ Excellent load stability
✅ Self-adhesive (cling property)
✅ Moisture & dust protection
✅ Cost-effective pallet securing
✅ Available in hand and machine grades
📦 Common Applications
🚛 Logistics & Warehousing
Pallet wrapping for transport
Securing cartons and bulk shipments
🏭 Industrial Use
Bundling pipes, metal rods, construction materials
Securing irregular or heavy loads
🛒 Retail & Distribution
Unitizing products before shipping to stores

🔥 Stretch Film vs Shrink Film
| Stretch Film | Shrink Film |
|---|---|
| No heat required | Requires heat |
| Used mainly for pallets | Used for retail & bundling |
| Elastic tension holds load | Shrinks tightly with heat |
| Cost-effective for logistics | Better product presentation |
