Unique Features of Thermal Lamination Film for Packaging
Thermal lamination films are surface coated with resin or a thermal adhesive that melts even in low temperature. This feature ensures that the lamination of paper products is possible simply by applying pressure and heat. There are three types of thermal films that come in two or three finishes. • • •
Biaxially oriented polypropylene film (BOPP) Biaxially oriented polyethylene terephthalate film (PET) Biaxially oriented nylon6 film (Nylon)
Features of BOPP thermal laminating films In this type of thermal laminating films biaxially oriented polypropylene is the base material. The process used to combine the layers of BOPP film and thermal laminating adhesive is extrusion coating. Therefore, the film has the properties of BOPP film on one side and the other side is heat sensitive and is used for dry lamination.
Advantages Of BOPP Thermal Laminating Film • •
The BOPP films are available in various decorative shades. People use this type of film to give an aesthetic look and feel to their products. The density of this film is approximately 0.90 g/m3 and is therefore cost effective when compared to polyester films.
