Novel environmentally-friendly lining paper for cigarettes

Abstract

The invention discloses a novel environmentally-friendly lining paper for cigarettes. The novel environmentally-friendly lining paper comprises a lining paper (1) and a barrier layer (2) coating the surface of the lining paper (1), a microcrystalline wax coating coats between the lining paper (1) and the barrier layer (2), and the barrier layer (2) is an aqueous polyvinyl alcohol layer. The novel environmentally-friendly lining paper utilizes microcrystalline wax, does not contain any solvent, has no pollution, is nuisanceless, has a fast curing rate and high operationality, only needs a hot melt coating process, produces viscidity by cooling and does not produce VOC residues.

Description

technical field [0001] The invention relates to an inner lining paper, in particular to an inner lining paper for cigarettes. Background technique [0002] The original identical or similar products are roughly classified into the following types by product classification: [0003] Ordinary printed lining paper: after compounding aluminum foil and lining paper, simple printing is carried out on the surface of the aluminum foil. And with the participation of aluminum foil, it is not environmentally friendly. [0004] Ordinary transfer-type lining paper: use vacuum aluminum-coated transfer film to directly laminate with the lining paper, and print after peeling off. This printing process also has a single color, but it replaces the traditional aluminum foil composite, and it also reduces the metal luster without losing the metallic luster. It reduces the cost and is environmentally friendly, but the performance of cigarette fragrance retention is poor, and it is a relatively...

AI Technical Summary

Problems solved by technology

[0006] The first kind of inner lining paper for cigarettes has simple and mature production process, weak market competitiveness and no high added value

It is not environmentally friendly, but it has excellent fragrance retention due to the participation of aluminum foil in compounding

Compared with the first kind, the second kind of cigarette lining paper replaces the traditional aluminum foil composite, and the process has been improved, but there will be various adverse phenomena such as poor formability of cigarette packs, faster smoke emission, and aluminum drop during production, which will affect the production of cigarettes. Appearance

Compared with the first two products, the third kind of cigarette lining paper has high added value, but the market demand is not large, and the packaging is too luxurious, which is a waste of resources. At the same time, because there is no aluminum foil, the smoke emits faster
