There are many processes in making coffee packaging bags, and "compositing" is one of the very important processes, which directly determines the quality of coffee bag packaging, so we need the help of packaging laminating machines.
The packaging laminating machine is to combine two or more layers of materials with an adhesive into a whole, so that the original materials can obtain new functions. Such as film and aluminum foil, film, paper, non-woven fabrics, etc. are often used. It can also be compounded with film, sponge, cloth, etc. Common coffee packaging bags are basically composite finished products.
Coffee packaging bags are generally laminated with two or three layers of packaging materials. The surface may choose kraft paper, the middle chooses aluminized film or aluminum foil film, and the innermost layer chooses PE film as the heat seal layer, and because of this layer The film will directly contact the food, so the hygiene of the material needs to be considered.
