With the development of the times, stretch film has started to be used in more and more industries, and stretch film makes our life or work more convenient. So what is stretch film?
Stretch film is a semi-transparent, glossy, soft film material with good chemical stability, heat sealability, water resistance and moisture resistance.
Stretch film is a stretch film material made from polyethylene terephthalate, which is extruded into a thick sheet and then stretched in both directions.
It is a colorless, transparent and glossy stretch film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance. Good chemical resistance, oil resistance, air tightness and fragrance retention, it is one of the commonly used base materials for permeability-blocking composite stretch films. However, the price of polyester stretch film is higher, the general thickness is 12μm, commonly used as the outer layer of steaming packaging materials, printing sex is better.
Tensile film has four characteristics respectively as follows.
1. Having excellent self-bonding properties.
2. Having good flexibility and stretchability.
3. Having high impact strength and puncture strength.
4. With shrinkage memory function.
