Technological process of poster folder gluer

The hot-rolled bonded nonwovens process of the poster folder gluer uses one or two pairs of steel rollers covered with other materials to heat and pressurize the fiber web, which causes part of the fiber web to melt and bond, the Mesh is reinforced to become a hot-rolled nonwovens. The hot-rolling bonding of the poster folder gluer is a very complicated process. During the process, a series of changes have taken place on poster folder gluer, including the pressing and heating of the web, the deformation of the web, and the melting of some fibers in the web, melt the flow of polymer and cooling forming, and so on. Poster folder gluer is the last process of packaging box processing.
