Plastic bags are made of plastic film, and the production process of the plastic film is first blow. It is the purchase of raw materials of plastic particles blown by the blow molding machine to form the order specifications of plastic film, plastic bags, then we can begin printing. In a plastic bag in a plastic ziplock bag printing process, we have to first printing plate according to the desired pattern, the printing unit version of the child and roll well and adjust the ink, you can start printing the. Completion of the above process can be completely formed on the plastic bag. 1.PE material: the material is divided into a high pressure (LDPE) and low feed (HDPE). From the appearance of the high-pressure feed is smooth, soft supermarket plastic bags manufacturers, toughness is good, a lot of handbag raw materials are produced using high pressure feed. Low pressure material tension well, high hardness, widely used in shopping malls, various procurement markets. The easiest method to distinguish between high and low, with Shredded produce white marks proved to be a low pressure, low pressure is due to the high density printed plastic bag factory, it will produce white marks, no white marks that tension is generally a good high pressure. 2.PP material: solid body hard, but relatively high transparency, clearer, tension is not very good, explosive mouth. Mostly for gift wrap, and finished apparel sales, we bought new clothes and have the kind of plastic bags wrapped layer of double-sided adhesive seal products are usually bags of po. PP bags very transparent, feels very slippery, there will be folded to its fold, folded PE bags do not. 3.OPP material: the most brittle material, the most transparent, tension is not enough, but the most explosive port and most likely bleaching printing gap is difficult if not torn, but there was a slight gap with a little effort you can not tear.
