Abstract

The invention relates to the technical field of composite kraft paper, in particular to five-in-one composite kraft paper. The composite kraft paper comprises a composite kraft paper body, and the composite kraft paper body comprises a kraft paper layer, a first PE film layer, a PE woven fabric layer, a second PE film layer and an EPE layer; the end surface of the kraft paper layer and the first PE film layer is fixedly provided with kraft paper convex portions, positions, located on the end surface of the kraft paper layer, of two adjacent kraft paper convex portions are fixedly provided withkraft paper concave portions, the kraft paper convex portions and the kraft paper concave portions are provided with a first adhesive layer, and the first PE film layer is adhered to the first adhesive layer; and one end surface, far away from the first adhesive layer, of the first PE film layer is adhered to a second adhesive layer, the second adhesive layer is arranged on upper PE woven fabricconvex portions and upper PE woven fabric concave portions, and the upper PE woven fabric convex portions and the upper PE woven fabric concave portions are fixedly arranged on the end surface of thePE woven fabric layer. According to the composite kraft paper provided by the invention, through the above arrangement, the properties of the composite kraft paper, such as tensile strength, punctureresistance, waterproofing and shock absorption can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of composite kraft paper, in particular to a five-in-one composite kraft paper. Background technique [0002] Kraft paper (kraftpaper), used as packaging material. The intensity is high. Usually yellowish brown. Semi-bleached or fully bleached kraft pulp is light brown, cream or white. Quantitative 80 ~ 120g / m2. The fracture length is generally above 6000m. Tear strength, work of rupture and dynamic strength are high. Mostly roll paper, but also flat paper. Using kraft softwood pulp as raw material, after beating, it is made on fourdrinier paper machine. It can be used as cement bag paper, envelope paper, glue seal paper, asphalt paper, cable protection paper, insulating paper, etc., but the existing kraft paper is relatively simple, and there are defects such as: making its strength toughness, tensile strength, and puncture resistance , waterproof, shock absorption and other performance problems. ...
