Heat Sealable Polyester Film for FRP Lamination

Heat sealable polyester films are essential components in the production of fiberglass reinforced plastic (FRP) laminates. These coextruded polyester films feature one side with a heat-sealable surface, allowing for efficient lamination processes in FRP manufacturing. The heat-sealable surface is specifically designed to adhere to itself, thermoformed APET, CPET, unsaturated polyesters, and paper substrates.

During the lamination process, the heat sealable polyester film serves as a crucial bonding agent, ensuring strong adhesion between layers of fiberglass and other materials. This enables the creation of durable and structurally sound FRP laminates suitable for various applications across industries.

It's important to note that heat sealable polyester films do not seal against polyolefin and PS (polystyrene) materials. Additionally, the seals formed using heat sealable polyester films are not peelable, providing enhanced security and integrity to the laminated structures.

In FRP manufacturing, the use of heat sealable polyester films streamlines the lamination process, improves efficiency, and contributes to the overall quality and performance of the final product. With their reliable sealing properties and compatibility with a range of substrates, these films play a critical role in ensuring the integrity and longevity of FRP laminates.
