Three-layers Laminating Pouches Its main ingredient

We only know that plastic bags do not know there are three layers of composite bag manufacturers, three-layer composite bag is layered shape. Three layers of composite bags are generally made of BOPP and coextruded films, BOPP and PET composites. Composite bags generally have two composite and three composite, composite bag general color printing, printing in the middle of the two films, the general tearing the side of the bag will appear two or three layers of this compound bag. Ordinary bags on a layer of surface printing, with a knife can scratch the top of the printing, and composite bag scraping off. Composite bags expensive, ordinary plastic bags cheap. The layered structure comprises at least a first film layer and a second film layer which are directly co-extruded and are arranged adjacent to each other and are mainly composed of one of the two kinds of plastic resins which are incompatible with each other. The first film is located on the surface of the composite plastic film. The main component of the first film layer is a polypropylene copolymer, and the main component of the second film layer is a polyester homopolymer. The composite plastic film disclosed in the utility model has not only different performance, but also easy to realize separation between at least two adjacent layers. It is a new type of aluminized layer or laser Molded film transfer special film.

Composite plastic bags, plastic flexible packaging in the actual use of them, due to the packaging of the items and physical differences in the protection of the performance requirements are also different. With a single type of plastic film made of packaging, is not up to the requirements. Such as heat sealing, load-bearing, gas-filled inflatable, oxygen-resistant, oil repellent, vacuum, cooking, anti-leakage performance. So you need to use several special features of the plastic film combination to be complementary, this combination of several types of film need to be bonded processing, composite film made of packaging to meet the needs of the packaging. Commonly used composite plastic film flexible packaging: transparent, color, black and white or color printing of plastic composite film packaging, aluminum plastic composite film packaging, metal foil composite plastic film packaging, paper composite plastic film packaging, paper, aluminum composite Plastic film packaging, composite plastic bags and so on.
