BOPET film acts as the foundation or substrate material for solar window film, providing structural integrity and durability. BOPET is chosen for its superior tensile strength, optical clarity, and dimensional stability, ensuring the film can withstand various environmental conditions and maintain long-term performance.
Certain solar window films are engineered to minimize heat penetration through windows. BOPET films can be coated with specialized materials, such as metals or ceramics, to selectively block or reflect solar heat, enabling better control of indoor temperatures. These films are often referred to as "heat rejection" or "reflective" window films.
