Functional lining body paper for cigarettes and preparation method of functional lining body paper

Abstract

The invention provides functional lining body paper for cigarettes and a preparation method of the functional lining body paper. The body paper is of a double-layer structure, one layer is a lining paper body paper base layer, and the other layer is a functional coating. The preparation method comprises the following steps: performing pulping treatment on a fiber raw material; adding a wet strength agent, a sizing agent, a defoaming agent, a retention aid and a reinforcing agent into the pulp after the pulping treatment is finished, performing uniform mixing, and applying the pulp to a mesh for treatment; performing squeezing dehydration treatment on the pulp subjected to treatment by the mesh to obtain the body paper base layer; coating the surface of the body paper base layer by a functional coating; and sequentially drying, coiling and slitting the coated body paper base layer to obtain the body paper. According to the invention, the surface of the body paper base layer of the lining paper for cigarettes is coated by the functional coating, so that the lining paper for cigarettes has high-barrier, moisture-preserving and moisture-preserving functions, and compared with conventional printing lining paper and pre-coated lining paper, the body paper of the lining paper for cigarettes has a lower water vapor transmission rate and a water absorption rate and higher wet strength.

Description

technical field [0001] The invention belongs to the technical field of base paper preparation, and in particular relates to a functional cigarette lining base paper and a preparation method thereof. Background technique [0002] In today's popular trend of international tobacco packaging, the demand for "environmental protection" is particularly important. The use of environmentally friendly packaging products is a "green pass" for tobacco companies to enter the world market. Both tobacco companies and tobacco packaging suppliers are increasingly aware of the necessity and urgency of using, developing and producing environmentally friendly products. The production and application of "green packaging" products will be the focus of the development of the tobacco industry and tobacco packaging industry in the next few years. [0003] At present, the development direction of base paper products for cigarette lining paper that replaces aluminum foil to achieve tobacco barrier a...

Problems solved by technology

However, these two types of lining papers have the following problems: 1) Both printed and pre-coated cigarette lining papers cannot achieve high barrier function; 2) Printed cigarette lining papers The speed of the finished paper composite machine for pre-coated cigarette lining paper is slow, less than 100m / min, and the width is less than 1 meter. The uniformity of the base paper banner has little effect on the running speed and quality of the composite machine; 3) Printed cigarette lining Regardless of whether the paper base paper is printed with water-based ink or alcohol-soluble ink, the base paper only needs to meet the printing performance, and there is no requirement for the dry and wet strength of the base paper; Cloth process, there will be no warping and other problems caused by the two sides of the paper, so there is no requirement for the deformation and dimensional stability of the base paper
