Coating process is divided into two kinds of semi-automatic operation and automatic operation. While semi-automatic and fully automatic in actual operation is somewhat different, in principle is the same: first by roller coating means applying an adhesive to the plastic film Tianjin Chemical kraft paper bags, heated by hot rollers, the film softens, then coated with a primer with print and lamination film, one of the film forming paper and plastic products. Kraft paper can be flexo printing, gravure printing, offset printing, screen printing process, as long as the master the essentials of printing technology, familiar with printing inks and kraft paper printability, reasonable selection and deployment of ink color kraft paper bags, control device parameters, can be obtained best quality results. But for some small-scale packaging and printing plants, or just put into production and operation of small brown paper packaging plant, due to various constraints, product quality but also there are some problems. Here to talk at Kraft in printing points to note: Note color printing press a wet coating method is a layer of adhesive plastic film applied to the surface, in the adhesive is dry condition, by a press roll and sticky paper print synthetic resin coated products. Since the advent of water-based laminating machine, water-based coating technology has been promoting the application of simple kraft paper and wet-coating process that has woven, adhesive with less damage to the environment does not contain organic solvents plus endometrial woven kraft paper bags, film printed with high-strength, high-grade, easy recovery and so are inseparable. Currently, the coating process more and more domestic packaging manufacturers of all ages, it has been widely used gift boxes and handbags like packaging. Under China's economic development so fast current situation, under the continuous improvement of people's consumption level cases, some non-traditional waste is waste generated in the consumer area, more and more like today we discussed packaging waste, may be a few Ten years ago, we do not put packaging waste as a problem, because the packaging industry is not very developed, kraft paper bag factory | kraft paper bags | packaging provided by Xiong Yu Xin Yu Xin plastic packaging plant.
