The conventional film coating technique is in the form of a glue coating, such as pre-coating with a solvent-based glue, water-based glue, or hot-melt adhesive on a film-covered material for hot pressing. The non-adhesive film is different, it does not use the conventional biaxially oriented polypropylene film (OPP), but the use of high-pressure polyethylene as the main material of the PE film, because the PE film has better thermal plasticity, PE After a special strong treatment is performed on one side of the film, the PE film can be heat-seal composited on the color printing paper using a non-adhesive laminating machine.
This non-adhesive film can withstand rubbing and does not foam, can withstand the temperature of 20 ~ 120 °C, and can stand rolling, cutting and so on. In the non-adhesive filming process, a layer of auxiliary material is interposed between the heat roller and the PE film, which is passed through the non-adhesive film laminator, and the film-covered product is then removed from the auxiliary material. Due to the different materials used, the same PE film can make a film, matte or other effects.
Adhesive-free coating technology does not use glue, and its advantages are very obvious: the cost is greatly reduced; there are no harmful gases that are easy to volatilize and infiltrate in the production, ensuring safety; easy to recycle, resulting in less waste; the film used in this technology The thickness is smaller and only less pressure is required during operation. The non-adhesive film technology is a process innovation for the existing PE film on the market.
