- What is metalized polyester film?
Metalized polyester film is a type of plastic film that has a thin layer of metal applied to its surface. This process enhances the film's properties, such as reflecting light and protecting against moisture, making it useful in packaging, insulation, and decorative applications.
- How is metalized polyester film manufactured?
The manufacturing process involves several steps:
- Starting with polyester resin, it is first extruded into a thin film.
- The film is then stretched (or oriented) to enhance its strength and clarity.
- Next, the film is metalized through a vacuum deposition process, where a fine layer of metal, commonly aluminum, is applied to one or both sides of the film.
- After metalization, the film may undergo further treatments to enhance its properties, such as coating for added durability and printability.
