The adhesive on a “hot” laminating film activates when the printed graphic is run through a hot-roll laminator at temperatures between 210 and 240 degrees. Because these high levels of heat can damage some types of inkjet graphics, “low-melt” or “heat-assist” films are also used. “Low melt” films have heat-activated adhesives that can applied at 185 to 195 degrees. “Heat assist” films have pressure-sensitive adhesives (PSAs) and liners and are applied with hot-roll laminators at 185 to 195 degrees.
“Cold” laminating films have a more aggressive adhesive that can be applied with pressure, instead of heat. A release liner protects the adhesive until it ready to applied, typically on a cold-roll laminator. Cold laminating films typically cost more than hot laminating films, but they can be applied using less costly, easier-to-operate non-heated laminators.
Cold laminating film use pressure sensitive adhesives, offers excellent adhesion without using heat. Laminating film can be mounted or laminated on different kinds of advertising materials, such as PP paper, vinyl sticker, photo paper, ect.It’s a cost effective way to protect the graphics from scratch, stain or moisture, will prolong the graphics’ using life. Good transparency PVC film, without any macula, good softness, easy to application on laminator or just by hand. Glossy cold laminating film will enable the graphics brightness, 3D cold lamination film will make the graphics with stereo feeling, special patterns lamination film will enhance the artistic effect.
