Calendered film is often broken up into three categories, which indicate its makeup and durability: • Monomeric (short term and rigid) • Mono-polymeric blend (mid-range) • Polymeric (longer term and more pliable) Lamination Films Lamination films are generally avail- able in cast or calendered, and are applied For a short-term promotion, this Mini Cooper was wrapped with un-laminated calendered film that has a water-based adhesive. It was tricky to install but had a great price point and removal was easy. to the graphic film layer. They protect it from physical damage, provide extra UV protection and give the film more body to help during the install process. The thicker the lamination layer the bet- ter the durability against wear and tear and the effects of exposure to UV rays from the sun. A thinner lamination layer provides more flexibility, yet it will often have a shorter warranty. The surface finish of the lamination layer can vary from matte, gloss or satin to textured and some (such as floor films) have anti-slip properties.
