BOPA laminating film is also known as flat or nylon laminating film. Flat Nylon Laminating Film is designed to minimize curling when laminating on one side. It can be used with most commercial laminators or single-sided laminators. Ideal for single-sided printing or high-speed lamination of documents. A low-melting copolymer adhesive is used. This adhesive provides excellent transparency. It also provides a strong bond between print and film. Most substrates laminated on one side can be dried in high humidity conditions. Lay Flat China Nylon/Bopa film uses materials that can change with relative humidity. So you get a great finished print that lays flat. These films can be made with foil stamping, UV spot varnishing, animal-based or synthetic adhesives.
