Embodiment 1

[0021] Embodiment 1: the method for preparing cigarette case or carton wrapping paper with cigarette rod as raw material, it is characterized in that concrete steps are as follows:

[0022] (1) Raw material pretreatment: the raw material of the tobacco rod is depilled by a wet method to remove half-fibers, and then sliced, and the tobacco rod is cut into 3cm fragments;

[0023] (2) Pre-rolling treatment: place the sliced ​​tobacco stems in step (1) and soak them in a steaming chamber for 360 minutes at a temperature of 60°C, and use a double-screw refiner to perform rough rubbing once, then The refining conditions of the twin-screw refiner are as follows: a conjugated twin-screw refiner is used, the screw diameter is 100mm, the screw speed is 200rpm; the compression ratio is 4:1; there are 5 blades on a single screw, and each blade is 360° There are 3 reverse spiral openings inside, the blade distance is 10mm, and they are distributed in a conjugated manner. The concentration ...

Abstract

The invention provides a method of preparing cigarette packet or carton packaging paper with tobacco stalks. The cigarette packet and carton packaging paper having natural tobacco aroma is prepared by: subjecting tobacco stalks as a raw material to wet depithing to remove hemicellulose, chipping, per-rubbing, pre-impregnating, steaming, performing fine rubbing, carrying out high concentration pulping, carrying out medium concentration pulping, carrying out up-flow pressure screening to obtain tobacco stalk papermaking pulp, and making paper according to an existing papermaking method; the cigarette packet and carton packaging paper has basic weight of 100-250 g / m<2>, whiteness of 15-35% (ISO), elongation of 1.5-3.5 Km, tearing index of 1.5-3.5 mN m<2> g<-1>, burst index of 1.0-3.0 kPa m<2>g<-1>, and folding endurance of 30-60 times. The tobacco-type cigarette packet and carton packaging paper is prepared herein with waste tobacco stalks; the development of tobacco materials can be promoted to green, sanitary, safe and recycling tendency; the cigarette packet and carton packaging paper also has decorating and anti-counterfeiting functions.

Description

technical field [0001] The invention belongs to the technical field of wrapping paper for cigarette boxes and cartons, in particular to a method for preparing wrapping paper for cigarette boxes and cartons with natural tobacco aroma from tobacco raw materials. Background technique [0002] The tobacco stem is the main stem of the tobacco plant. The tobacco rod is full of well-developed pith, which can store nutrients and water. As the tobacco grows and matures, the nutrients and water will continue to decrease. At present, the tobacco stems after harvesting are mostly abandoned fields, which are decomposed, and they are also recycled and reused as fertilizer or biochar, but they have not been scaled up. The wrapping paper of cigarette boxes and cartons is an important part of cigarette packaging materials. In recent years, its safety and sanitation, environmental protection, renewable resources and packaging value have been highly concerned by the tobacco industry. Conten...
