Production process of composite packaging bags
Composite packaging bags, also known as three in one composite bags, have become one of the popular and useful commonly used packaging materials due to their high strength, good waterproofing, and beautiful appearance. What is the production process of composite bags? The production process of composite bags is not a difficult operation for manufacturers, but the staff should take it seriously. In the production process of composite bags, the following points should be achieved: 1. Composite packaging bags are used for document layout (or supply sample bags 2. Layout admission requires a deposit to be paid and organized for production. 复合包装袋的生产工艺 If you want to make a plate, you will have a machine cost. The production process of composite packaging bags is cumbersome. It is necessary to plate and print on machines. Use a laminating machine to laminate twice, then place it in a drying oven for 48 hours, cut it with a slitting machine, and then make a bag Packaged, passed quality inspection and packaging. Each process is costly, labor-intensive, and time-consuming. Before printing the composite packaging bag, the printing factory will provide a color draft, and the color can be adjusted according to the on-site color draft. 5. Wet composite method for composite packaging bags: Wet composite method, also known as wet lamination, has the following process flow: One layer of substrate (such as plastic film, aluminum foil, etc.) is coated with water-soluble or water-based adhesive, extruded, and then compounded with two layers of substrate (such as paper, glass paper, etc.). ）By using a composite device in a wet state and then drying in a hot oven to remove the solvent, the two layers of substrate are combined together. 6. Coating method of composite packaging bag: refers to the method of coating a flowing substance on the outer surface of the film to make the outer surface of the film closely fit with the surface facial mask. It can improve the thermal adhesion, moisture resistance, gas insulation, ultraviolet absorption, and anti-static performance of the film. The so-called multi-layer composite bag or composite bag aluminum foil bag refers to a packaging material composed of two or more layers of film, which can be plastic film, aluminum foil metal material, paper, etc. The essential difference between composite bags and single-layer bags is that single-layer bags are made of a single layer of material, while composite bags are made of two or more layers of material. Such as single-layer OPP bags, single-layer PE bags, composite OPP/PE bags, composite OPP/CPP bags, etc. Aluminum foil bags for composite bags require higher technology and more advanced packaging machines.
