What Is Shrink Film in Packaging Industry
Shrink film is a thin plastic packaging roll material.
It will contract tightly when receiving proper heat.
It clings closely to the surface of wrapped goods.
It bundles separate items into a complete unit.
It provides physical protection during logistics and sales.
Common raw materials include PE, POF and biodegradable blends.
Core Working Principle of Heat Shrink Film
Heat shrink film owns special molecular stretching structure.
Heating breaks the fixed stretched molecular state.
Material shrinks back to its original loose size.
Uniform heat brings smooth and wrinkle-free wrapping effect.
Different film types match different heating equipment.
Temperature range varies for biodegradable heat shrink film.

Main Categories of Conventional Shrink Film
PE shrink film takes the largest market share in industrial packaging.
POF shrink film features high transparency for retail product display.
PVC shrink film is phased out due to harmful heating fumes.
Each category has unique thickness and shrink ratio options.
They serve beverage, daily chemical and construction industries.
Conventional films cannot fully break down in natural environments.
Definition & Core Traits of Biodegradable Shrink Film
Biodegradable shrink film is upgraded eco heat shrink packaging material.
It mixes PE base with fully degradable bio additives.
It keeps all packaging performance of standard shrink film.
It breaks down into water and CO2 under compost conditions.
No toxic microplastic residue left after degradation cycle.
It complies with global plastic pollution control policies.

Core Performance Testing Standards for Biodegradable Shrink Film
Performance testing is the core of qualified biodegradable shrink film quality control.
Dimensional deviation testing ensures consistent film thickness and width accuracy.
Mechanical tests verify tensile strength and tear resistance of heat shrink film.
Degradation rate testing detects biodegradation efficiency under compost conditions.
Barrier performance tests check water vapor and gas permeability of the film.
Shrinkage rate testing guarantees stable wrapping effects after heating.
Practical Tips to Choose Suitable Shrink Film
Confirm your heating machine type before picking heat shrink film.
Match film thickness based on the weight of packaged goods.
Select biodegradable shrink film if targeting eco market channels.
Check transparency demand for supermarket retail products.
Ask suppliers about custom printing service for brand rolls.
Verify degradation standards for cross-border export business.
