Feature
Silica Powder is a commonly used additive in the manufacturing of transparent plastic PET roll film. It is added to the plastic
resin during the production process to enhance the film's mechanical properties and improve its transparency.
The addition of silica powder helps to increase the film's tensile strength, making it more durable and resistant to tearing. It
also improves the film's dimensional stability, reducing the risk of shrinkage or warping over time.
Furthermore, silica powder can enhance the optical properties of the PET film, making it more transparent and clear. This
is particularly important for applications where high clarity is desired, such as packaging films or display windows.
In addition to its mechanical and optical benefits, silica powder can also provide other advantages to PET roll film. It can act
as a processing aid, improving the film's melt flow properties and reducing the risk of processing defects. It can also act as a
moisture absorber, helping to prevent moisture-related issues such as brittleness or fogging.
Overall, the addition of silica powder to transparent plastic PET roll film can significantly improve its performance and
appearance, making it a popular choice in various industries.
