What factors will affect the heat shrinkable film performance of PVC?

    PVC heat shrink film is widely used in the packaging industry. It is known for its excellent performance and ability to protect products, but it can be affected by a variety of factors. 

     First, the temperature of the processed material has a great influence on the performance of PVC heat shrink film. The temperature should be controlled within a certain range, and the temperature change will affect the quality of the film. 

     Second, the humidity of the environment will also affect the performance of PVC heat shrink film. With the increase of humidity, the effect of shrinkage and tightness of the film will be weakened, resulting in poor quality of the product packaging. 

     Third, the thickness of the PVC heat shrink film has an important influence on the effect of shrinkage and tightness. If the thickness is too small, the effect of shrinkage and tightness will be weakened, resulting in poor quality of the product packaging. 

     In addition, the quality of the film itself will also affect the performance of PVC heat shrink film. If the quality of the film is not good, the shrinkage effect and tightness will be weakened, and the product packaging effect will be poor. 

 Therefore, in order to ensure the quality of PVC heat shrink film and the effect of product packaging, we must pay attention to the above factors and ensure that the environment and other conditions are suitable for the use of PVC heat shrink film.
