Polyester BOPET film

BOPET, or biaxially oriented polyethylene terephthalate, is a type of polyester film that can serve various purposes in the lamination of FRP (Fiber Reinforced Plastic) panels. Here are some potential functions of BOPET film in the lamination process:

1. Release Liner:

• BOPET film can act as a release liner during the lamination process. It provides a smooth and non-stick surface, preventing the FRP panel from sticking to the rollers or other surfaces during the curing or lamination process. This facilitates the easy release of the panel once it has been laminated.

2. Surface Protection:

• BOPET film can be used to protect the surface of the FRP panel during handling, transportation, and storage. This protective layer helps prevent scratches, abrasions, or other damage to the panel's surface, ensuring that it reaches the end user in optimal condition.

3. Enhanced Adhesion:

• The use of BOPET film may enhance the adhesion between the FRP panel and the resin during lamination. It can provide a consistent surface for resin application, promoting better bonding between the fiberglass reinforcement and the matrix resin. This can result in improved overall performance and durability of the FRP panel.

4. Barrier Properties:

• BOPET film can contribute to the barrier properties of the FRP panel. It may act as a moisture barrier, preventing water or other environmental factors from penetrating the panel and affecting its structural integrity. This is particularly important in applications where moisture resistance is critical.

5. Aesthetic Enhancement:

• In some cases, BOPET film with specific visual properties or finishes may be used for aesthetic enhancement. It can provide a glossy or matte surface finish, contribute to color consistency, or even offer customized printing for branding or decorative purposes.

6. Process Efficiency:

• BOPET film can improve the efficiency of the lamination process. Its release properties and compatibility with resins can help facilitate smooth processing, reduce the likelihood of defects, and contribute to the overall efficiency of manufacturing FRP panels.

The specific function of BOPET film in FRP panel lamination can depend on the desired properties of the final product, the manufacturing process, and the requirements of the application. Manufacturers may choose BOPET films based on their unique combination of mechanical, thermal, and barrier properties to achieve the desired performance in the FRP panels.
