The editor will explain to you belowu003c/pu003eu003cpu003eu003c/pu003eu003cpu003e1. Improper temperatureu003c/pu003eu003cpu003eWhen laminating different substrates, the temperature of the electric heating steel roller must be Cover the product to adjust. If the adjustment is improper, the coated product will not be bright. When laminating, sometimes there are a lot of water droplets or steam on the silicon roller, which is caused by the paper absorbing a lot of water. The temperature of the film must also be increased. u003c/pu003eu003cpu003e2. Insufficient pressureu003c/pu003eu003cpu003eMany of the thickness of substrate materials are different. When laminating, the pressure between the silicone roller and the steel roller should be adjusted according to the thickness of the paper. If the pressure is too low, the film of the coated product will be weak, not bright, and easy to wrinkle: if the pressure is too high, the film will wrinkle and the paper will be deformed. u003c/pu003eu003cpu003e3. Glue outputu003c/pu003eu003cpu003eWhen using stretched polypropylene film to cover the film, glue should be applied to the film. The amount of glue applied is applied to the moving film through a transmission steel roller installed in the glue box through rotating belt glue. The glue amount is controlled by a steel blade that falls on the steel roller. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003e4. Roller cleaningu003c/pu003eu003cpu003eAfter a long time of pressing, the steel roller is in direct contact with the film, and the temperature effect will leave some residue on the steel roller. The thing is on it. The silicone roller is directly in contact with the back of the coated product paper, and coupled with the separation of the paper feeding distance, a lot of glue is directly pressed onto the rubber roller and accumulates, which will affect the brightness of the coated product. u003c/pu003eu003cpu003eThe above is the non-woven bags manufacturer, explaining the 4 reasons for the poor printing of the film-coated non-woven bags.
