The laminating machine refers to a single layer coating on the surface of a substrate such as paper, film, aluminum foil or non-woven fabric such as PP, PE, etc., and the laminating machine means that there are two kinds of substrates. Composited by PE, PP, etc. Both machines can be called laminating machines. The basic design principles of the two machines are the same. The laminating machine is double unwinding, and the laminating machine is a single unwinding. Single-host dual-mode double-sided laminating composite unit and dual-host dual-die surface laminating laminating unit are suitable for single-unit one-time extrusion of two layers of plastic cast film (TPU, EVA, PE, etc.) with woven bags and OPP film. , PET film aluminum film, carbon fiber and other materials single layer coating or lamination composite.
