What is thermal lamination film?
Thermal lamination film is a decorative film that has been extrusion coated with a thermal adhesive so that a heated lamination nip roll will activate the adhesive layer causing the film to adhere to a printed paper surface. The decorative film can be a biaxially oriented polypropylene film (OPP), a biaxially oriented polyethylene terephthalate film (PET), or a biaxially oriented nylon-6 film (Nylon). The decorative film can also be glossy, matte finish, or have a special modified surface for foil stamping or special adhesives such as those used in making case bound books.
What are its applications?
The applications are many, ranging from a one sided lamination to a paperback book, called a “perfect bound”. These laminated papers can also be used in a “case bound” construction where there is a very stiff paper structure giving strength to the book. Some printed papers are sandwiched between two layers of lamination film such as seen for menus, identification cards and such.
What advantages do thermal lamination films offer for print finishing?
The primary advantage of a thermal lamination film is the strength and protection given to the laminated print surface. The alternative is a coating for the print, called a “varnish” which does not have the strength, abrasion resistance and such. Thermal lamination gives flexibility, abrasion resistance, water resistance, solvent resistance, and scratch resistance.
