Feature
Silica dioxide, also known as silicon dioxide or silica, is a commonly used additive in PET printing film. It is used to improve
the properties of the film, such as its mechanical strength, barrier properties, and surface smoothness.
When added to PET printing film, silica dioxide acts as a reinforcing filler, enhancing the film's tensile strength and tear
resistance. This makes the film more durable and less prone to damage during handling and transportation.
Silica dioxide also improves the barrier properties of PET printing film by reducing the permeability to gases such as
oxygen and moisture. This helps to protect the contents of the packaging, such as food or pharmaceutical products,
from external factors that could affect their quality and shelf life.
Additionally, silica dioxide can improve the surface smoothness of PET printing film, resulting in better print quality and clarity.
It helps to reduce the occurrence of defects such as pinholes or streaks, ensuring a more visually appealing final product.
Overall, the addition of silica dioxide to PET printing film enhances its performance and makes it more suitable for various
applications, including packaging, labeling, and graphic printing.
