First of all, according to the national standard, the packaging materials of tea packaging bags are PET, PE, AL, OPP, CPP, VMPET, etc. The most commonly used structure is PET/AL/PE. Let's first look at the production process of tea packaging bags: printing--inspecting--coding--compounding--curing--slitting--bag making 1. Printing There are printed and non-printed packaging bags. The cost of non-printing is lower than the cost of printing. Because one of the colors needs to be made of a plate roller, so there are several plate rollers for several colors. When making plates, it is best to find a large company to do it, and the quality and service are relatively guaranteed. The quality of the printing machine is also very important, such as printing speed, correction in printing, etc. If there is a problem, it will affect the overall delivery time. two. The inspection of the product is usually done after printing and during the process, that is to say, if you do not use printed tea bags, you do not need to inspect the product. First of all, it must be clear that the inspection product is a machine, and the printed film is tested according to the set data. . three. Coding For customers who have coding requirements, the products can be coded. Four. Composite lamination is to stick several kinds of films together with the corresponding glue. Some of the parameters are not important to talk about. Here we mainly talk about the classification of composites. , extrusion compound. They each have advantages and disadvantages. five. Curing Curing is to let the adhesive volatilize, mainly the residual adhesive during the previous compounding. Different packaging and roll film packaging of different products have different curing times. six. Slitting Whether it is making bags or film rolls, slitting can be used, because the printed products are relatively wide, and to produce the specifications required by customers, slitting is a key step. seven.
