3-ply reflective solar tinted film refers to a type of window film that consists of three layers. Each layer serves a specific purpose in enhancing the film’s performance and durability.

• The first layer is typically a polyester base, which provides the film with its structure and flexibility. Polyester is a common material used in window films because it is durable and resistant to tearing, creasing, and bubbling.
• The second layer is a thin coating of metal or metal oxide deposited onto the polyester base. This layer is responsible for the film’s reflective properties, as it reflects a portion of the sunlight that strikes the window. The choice of metal or metal oxide determines the film’s level of reflectivity and heat rejection.
• The third layer is an adhesive layer that bonds the film to the glass surface of the window. This adhesive is usually pressure-sensitive, allowing for easy installation without the need for additional adhesives or activators. The adhesive layer ensures that the film remains securely attached to the window, even in challenging environmental conditions.
