Choosing between stretch film and shrink film is one of the most common dilemmas in warehouse operations and logistics. While both materials provide load stabilization and dust protection, their application methods, cost structures, and holding dynamics are vastly different.
How stretch film works
Stretch film is manufactured with high-elasticity LLDPE that is stretched around a pallet load. The elastic recovery force keeps the boxes tightly bound together without requiring external heat application.
When to choose shrink film
Shrink film is loosely applied over items and then exposed to a heat tunnel or heat gun. The heat causes the polymer to contract tightly around irregular shapes, creating an airtight, weather-proof outer shell.
Comparison summary for logistics
- Stretch Film: Best for standard pallet wrapping, fast high-throughput automated lines, and cost efficiency.
- Shrink Film: Best for odd-sized machinery, marine transit, weather-proofing, and bundle wrapping (bottles/cans).
