1. Material properties
Roll heat shrink film:
Material: POF (Polyolefin)
Transparency: High transparency, can clearly show the product in the package
Shrinkage characteristics: It will shrink evenly when heated and stick to the surface of the product
Thickness: Usually thin, suitable for light and medium weight product packaging
Stretch wrap film:
Material: LDPE (Low-Density Polyethylene)
Transparency: Transparent or translucent
Stretching characteristics: It has good stretchability and elasticity, can be stretched multiple times, and is used to wrap and fix products
Thickness: Usually thick, suitable for bundling and fixing heavy and large products
2. Usage
Rolled heat shrink film:
Usage: Heating equipment is required, such as a heat shrink machine, which shrinks the film and fits the product tightly by heating
Packaging effect: Closely fits the product surface, providing good protection and display effects
Main uses: Packaging of food, medicine, cosmetics, and small items
Stretch wrap film:
Usage: Stretch the film and wrap it around the product or pallet manually or automatically without heating
Packaging effect: Mainly used to bundle and fix products to prevent them from moving during transportation and storage

3. Application scenarios
Rolled heat shrink film:
Food packaging: such as candy, biscuits, bread, etc.
Medical packaging: medicines, medical devices
Cosmetic packaging: skin care products, cosmetics
Other small items: such as toys, stationery, and crafts
Stretch wrap film:
Industrial packaging: such as machinery and equipment, building materials
