Unbleached tissue packing paper and production method thereof

Abstract

The invention relates to an unbleached tissue packing paper and a production method thereof, and belongs to the field of tissue packing paper in the papermaking industry. The whiteness of the unbleached tissue packing paper is 35-50%, a pulp used in the production of the unbleached tissue packing paper comprises 20-30% of wood pulp and 70-80% of unbleached straw pulp, and the beating degree of the unbleached straw pulp is 42-53DEG SR. The unbleached straw pulp with low beating degree is mainly used by the unbleached tissue packing paper, so a technical prejudice that the production of tissue packing paper needs the straw pulp with high beating degree is overcome; the produced paper has the advantages of high strength, low cost, environmental protection, no toxic substances, wide application range; the production method overcomes the problem of high difficulty of the production of the tissue packing paper from the straw pulp; and the produced tissue packing paper has also has uniform quality, good transparency and high physical strength.

Description

technical field [0001] The invention relates to an unbleached thin-leaf wrapping paper, which belongs to the field of thin-leaf wrapping paper in the papermaking industry, in particular to an unbleached thin-leaf wrapping paper produced by using wood pulp and unbleached paper pulp and a preparation method thereof. Background technique [0002] Tissue wrapping paper, also known as Sydney paper, has a weight of 22g / m 2 The following types of wrapping paper are collectively referred to as packaging paper for fruit, clothing, shoes, leather goods, hardware, porcelain, wine, and handicrafts.

Problems solved by technology

[0011] However, the high beating degree of pulp has the following problems: first, increasing the beating degree of straw pulp will lead to prolonged beating time, increased power consumption, and reduced production capacity; Squeeze rollers and sticky cylinders will cause paper sheets to break and increase paper defects, which directly affect the speed and productivity of the paper machine; thirdly, due to the shearing action of the roller knife and bottom knife of the beating equipment, increasing the beating degree will lead to Straw pulp fibers are excessively cut, which greatly reduces the strength of the paper, especially the tearing degree

More did not find the preparation method of the tissue wrapping paper that adopts the unbleached straw pulp of lower beating degree and wood pulp to prepare
