Paper bags are made of a composite of plastic and kraft paper, generally plastic layer is made of polypropylene (PP) or polyethylene (PE) as a base material flat yarn woven, kraft paper kraft paper is used special refining complex, high strength, waterproof good, look beautiful features. Is one of the most popular packaging material, is widely used in plastic raw materials, cement, feed, chemicals, fertilizer and other industries. Laminating release paper after paper by lamination, in lamination surface coating release agent, derived from the release paper production. Because the paper surface of paper, wool and fiber, so Laminating must to a certain amount, in order to ensure that no infiltration point, in order to ensure the silicone oil will not penetrate into the paper, in order to ensure there will be no adverse peeled off. Usually coated paper lamination amount of 16 grams per square meter, is said to have done the Wenzhou region of 11 to 13 grams per square meter white snakeskin bag, very close to the foreign advanced equipment Laminating data. In theory, as long as they ensure woven tape peeled from the release paper, then lower the amount of lamination are permitted because the printed products are mostly made of resin type of light quick-drying ink. Therefore, resin-based ink film surface adhesive resin-based adhesive will be very easy, for the corresponding adhesive fastness, resinous adhesive generally use more than two tons of chemical composition package bags, which increases the difficulty of the operator to a certain extent. For example: A and B components ratio of the two resins. After mixing the adhesive life and other issues will directly affect the degree of adhesion of white transparent bags, however, as long as strict focus on production processes off it can be solved. Since Kraft Unlike SBS paperboard and general printing paper, it is uncoated, than bleached paperboard loose, the surface has many pores, permeability relatively strong, it needs to do a comprehensive in terms of ink and coating applications consideration. For example, according to the analysis of the characteristics of kraft paper, generally used in flexographic printing it is better, but not appropriate to conduct full offset printing kraft paper. Because kraft paper rough surface, soft texture, strong ink, printing color dull, and printing inks will appear to pull down the paper fibers (also known as pull-off paper hair) phenomenon.
