What role will the performance of stretch film play

1. Barrier performance: According to the different requirements of product packaging, stretch film should have a certain blocking effect on moisture, water vapor, gas, light, aroma, peculiar smell, heat, etc.
2. Certain mechanical properties: the film should be able to effectively protect the product, so it should have certain strength, toughness and elasticity to adapt to pressure and impact; Influence of static and dynamic factors such as vibration.
3. Good safety performance: the toxicity of the stretch film itself should be small, so as not to pollute the product and affect human health; Packaging materials should be non-corrosive, and have insect-proof, moth-proof, rat-proof, inhibition of microorganisms and other properties to protect product safety.
The performance of stretch film will inevitably have problems when applying, which requires users to pay attention to the use of the process at all times, if the problem is found, regardless of the degree of it must be solved immediately, can not let the small problem have time to develop into a larger problem, to bear the basic responsibility for the use of the effect.
