Problems solved by technology

[0002] The existing vacuum aluminum-coated paper and moisture-proof paper are widely used in cigarette, food, daily chemical, and decoration industries. Due to quality reasons, vacuum metal-coated paper and moisture-proof paper have poor longitudinal tensile strength and are only suitable for low-speed production lines. It is especially not suitable for use on high-speed cigarette rolling machines in the tobacco industry, otherwise paper breaks will easily occur

Abstract

The invention discloses a production method for a lining paper for a cigarette. The production method comprises the following steps: A) preparing grinding pulp, and then allocating the pulp which contains 15-30 wt.% of bleached needle bush pulp, 55-75 wt.% of bleached hardwood pulp and 10-15 wt.% of straw pulp, separately pulping, and then mixing the grinding pulp, and controlling pulp intensity at 30-40 OSR and wet weight being 2.5-5.5g; B) adding padding and a degassing agent before primarily slushing the pulp, and then entering into multi-stage deslagging; C) adding pulp glue and starting the secondary slushing; D) after ending the secondary slushing, adding a sizing agent, placing into a pressure screen for treating, and adding a retention agent at an outlet of the pressure screen; E) pouring the pulp into a pulp flowing box, loading a net and preparing paper with the pulp; F) extracting and dewatering; G) drying; H) performing soft calendaring dual-pressing treatment; and I) coiling, rewinding and cutting, packaging and putting into a storage. The lining paper for the cigarette produced according to the production method has the beneficial effects: the paper sheet uniformity is excellent; the horizontal width rated difference is small; the tensile force is high; the lining paper is easy to cut; the front surface of the paper sheet has higher smoothness; and the back surface of the paper sheet has certain smoothness.

Description

technical field [0001] The invention relates to a production method of inner liner paper for cigarettes. Background technique [0002] The existing vacuum aluminum-coated paper and moisture-proof paper are widely used in the cigarette, food, daily chemical, and decoration industries. Due to quality reasons, vacuum metal-coated paper and moisture-proof paper have poor longitudinal tensile strength and are only suitable for use on low-speed production lines. It is especially not suitable for use on high-speed cigarette rolling machines in the tobacco industry, otherwise paper breaks will easily occur. As an improvement, in the prior art, composite aluminum foil paper is formed by compounding aluminum foil backing paper and calendered aluminum foil. Compared with vacuum aluminized paper and moisture-proof paper, the composite aluminum foil paper has greater advantages, especially as a cigarette inner lining. Paper is used in high-speed cigarette making machines, but the produc...
