Lamination is a process that involves bonding a thin, transparent film — typically, polypropylene, polyester, or nylon — to the surface of the press sheet or other substrate. Film lamination process offers a variety of options to choose from. People generally opt for lamination to protect the print products from wear and tear.
Polypropylene is the most commonly used film. People come in contact with this material on a regular basis. It is commonly found in books, candy wrappers, chips packaging, CD and DVD cases.
Polyester Film (Mylar):
Polyester provides excellent scuff, scratch and tear resistance. The ﬁlm’s copolymer adhesive creates an excellent bond to a variety of offset printed stocks, including coated sheets and prints with heavy ink coverage. Krystal ﬁlm is available in a variety of gauges for one- and two-sided lamination and encapsulation.
Nylon films are best suited for creating flat and durable laminated digital prints.
Lay-Flat Laminate is a nylon based film that allows single-sided laminated paper and graphics to adjust to humidity and helps eliminate the curling of laminated products. Commonly used with book covers, dust jackets, brochures and magazines, nylon film keeps them flat even in humid conditions.
