Paper bags are made of a composite of plastic and kraft paper packaging bags of potatoes, usually 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, has high strength, waterproof, beautiful appearance characteristics. 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 tons pack bags, reportedly Wenzhou has done 11 to 13 grams per square meter, very close to the foreign advanced equipment Laminating data. In theory, as long as they ensure the tape from the release paper peeled off, and then the low amount of lamination are permitted 3. CCK CCK release paper after paper is coated with a surface layer of special clay coated release agent, derived from the release paper production. Because of its high temperature properties, especially good white snakeskin bags, are widely used in the carbon fiber industry. Clay easily CCK silicone base paper surface damage, so the domestic production of CCK release paper can really pass is still a minority. 3, large bags, brown paper bags counter-head, thick yellow paper bags, kraft paper bags these practices to be handmade, currently the country has failed to solve these kraft paper bag forming machine, only handmade, and this Class of kraft paper bags in higher production costs, the number will not be great. 4, no matter what kind of paper bags above, if the number is not large enough generally use handmade paper bags because the machine production loss, no solution to the small number of brown paper bags practices.
