Abstract

The invention discloses a kraft paper adhesive tape and a preparation process thereof. The kraft paper adhesive tape comprises a base material, a first dipping layer, a second dipping layer, a releaselayer and an adhesive layer, wherein the first dipping layer and the second dipping layer are formed on two sides of the base material, the release layer is positioned on the first dipping layer, andthe adhesive layer coats thesecond dipping layer. The kraft paper adhesive tape provided by the invention can be used for easily writing, and can be used for freely and clearly writing regardless ofpencils, ballpoint pens and water color pens, so that the practicability of the adhesive tape is greatly improved.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a kraft paper tape and a preparation process thereof. Background technique [0002] Kraft paper is a tough and water-resistant packaging paper with a brownish-yellow color and a wide range of uses. It is often used to make paper bags, envelopes, workbooks, record sleeves, files, and sandpaper. Quantitative range is 80 g / m2 to 120 g / m2, there are differences between roll paper and flat paper, single-sided light, double-sided light and stripes. The main quality requirements are flexible and strong, high burst resistance, and can withstand large tension and pressure without breaking. Kraft paper has high tensile strength, and there are single light, double light, stripes, no lines, etc. It is mainly used for wrapping paper, envelopes, paper bags, etc., and printing machine cylinder lining, etc. [0003] The kraft paper tape is a kind of adhesive product prepared by using it as ...
