Why shrink wrap is more than aesthetic — and where it earns its keep during monsoon season.
Heat shrink wrap is a polymer plastic film, typically polyethylene or polyolefin, that contracts when heated to form a tight seal around cargo. It's a staple in modern logistics and shipping.
Why it earns its place
- Shields goods from environmental damage, moisture, and UV rays.
- Provides visible security against tampering.
- Prevents cargo shifting during transport.
- Costs less than crating on many configurations.
How it's applied
The cargo is wrapped with shrink film, then heat is applied via a heat gun or tunnel, causing the material to contract and conform snugly to the goods' surface.
Film varieties
- Polyethylene — affordable and common.
- Polyolefin — clearer with better puncture resistance.
- Cross-linked films — heavy-duty applications.
What to consider
Choose based on film thickness, cargo dimensions, environmental exposure, and equipment compatibility. The technique works well for irregular shapes and large items across manufacturing, construction, agriculture, and retail.
