Precoated laminating machine adopts the form of plastic laminating, such as the use of solvent volatile glue, water-based glue or hot melt glue precoated on the film material for hot pressing.

Without glue type laminating machine is different from the pre-coated laminating machine, without glue coated not adopt conventional two-way stretch polypropylene film (OPP), and use high pressure polyethylene as the main ingredient of the PE film, PE film has good hot melt and the plastic, the side of PE film after strong special processing, can use the hot melt glue laminating machine to PE membrane composite in color printing paper. This non adhesive film can withstand the temperature of 20~120℃, PE film is a surface van der Waals force is weak material, wax additive composition makes its surface appear a weak interface layer state. As a result, it under the low temperature hot melt state, with the paper bonding strength is smaller, so there is no glue laminating process, need between the heating roller and PE membrane mat into a layer of auxiliary materials of PE film on one side of the surface (special treatment), they passed by without glue laminating machine, stripped of coated products and out of the auxiliary materials. In addition, there is a glue-free film coating process of glue-free composite film, which can be directly combined with paper without glue at a certain temperature and pressure, and is mainly used for self-adhesive label coating.
