Embodiment 1

[0024] Prepare the ultra-high bulkiness face bowl paper of the present invention according to the following methods:

[0025] 1. Pulping process

[0026] Surface layer:

[0027] The ratio of surface layer pulp is: 35% NBKP (bleached softwood kraft pulp) + 65% LBKP (bleached broadleaf kraft pulp);

[0028] After the pulp board is disintegrated by a hydraulic machine according to a certain ratio, it is sent to the paper machine for papermaking through screening, beating, and pulping.

[0029] ② Core layer:

[0030] The ratio of core pulp is: 50% BCTMP (bleached chemical thermomechanical pulp) + 20% BKP (bleached broadleaf chemical pulp) + 30% broken paper;

[0031] After the pulp board is disintegrated by a hydraulic machine according to a certain ratio, it is sent to the paper machine for papermaking through screening, beating, and pulping.

Abstract

The invention discloses ultrahigh-loose thickness noodle bowl paper. The ultrahigh-loose thickness noodle bowl paper comprises a surface layer, a core layer and a bottom layer, wherein both the surface layer and the bottom layer comprise bleached needlebush sulfate pulp, and the content of the bleached needlebush sulfate pulp in the surface layer and the bottom layer is 35 to 50 percent by weight. The invention also provides a production process of the ultrahigh-loose thickness noodle bowl paper. On the premise of improving the loose thickness of the noodle bowl paper, the difficulties of curling cracking, side seepage and oil seepage can be solved.

Description

technical field [0001] The invention relates to a bowl paper, in particular to a bowl paper with super high bulk. The invention also relates to the production process of the ultra-high-bulk tissue paper. Background technique [0002] In the post-processing process, one or both sides of the bowl paper are usually covered with a layer of PE film, so as to block the penetration of water and oil, but the die-cut edge is not blocked by the film, so it is easy to cause the penetration of water and oil . [0003] Ordinary noodle bowl paper is less prone to crimping and cracking due to the lower bulkiness of the slurry, and side seepage and oil seepage are easier to control. However, such tissue paper for face and bowl uses more wood raw materials, resulting in higher production costs. [0004] In order to reduce the use of wood raw materials, it can be considered to use high-bulk pulp for production, which can reduce the production cost of bowl paper. However, due to the use o...
