Core Definition of Shrink Film
Shrink film is a flexible plastic packaging material.
It can shrink tightly to fit product surfaces under proper heating conditions.
It provides stable wrapping and basic protection for various goods.
It is applicable for single products and multi-piece product sets.
Working Principle of Heat Shrink Film
Heat shrink film relies on thermal shrinkage physical properties.
The film expands and stretches during production processing.
External heat triggers the film to retract rapidly.
It closely adheres to product contours without extra gaps.
Heating temperature and time affect the final shrinking effect.
