Problems solved by technology

However, due to the complex process of aluminizing technology, the production cost is high, and because no fiber is added to the stone paper during the manufacturing process, the lining paper after aluminizing has a small stiffness and a large rebound after folding, which is difficult to meet the requirements of modern high-speed cigarette production. Demand (500~800 packs / min)

Abstract

The invention relates to high-barrier environmental-friendly coating lined paper and a manufacturing method thereof. The lined paper comprises following three layers: a stone paper layer, an ink layer on the surface of the stone paper layer and a high-barrier layer on the surface of the ink layer. The gram weight of the stone paper base material is 55-80 g/m2. The ink layer is a coating formed by drying aqueous soybean ink. The barrier layer is a coating formed by coating base material paper with modified polyvinyl alcohol coating and drying. The modified polyvinyl alcohol coating is prepared by polymerization of following raw materials by weight: 4-7% of polyvinyl alcohol, 5-9% of carbon nanofiber, 3-6% of citronellal, 3-7% of a catalyst, 2-7% of a defoaming agent and 70-79% of softened water. The lined paper has characteristics of excellent barrier performance, good stiffness and strength, capability of environmental protection and low production cost, and can fully replace traditional composite lined paper or aluminized lined paper.

Description

technical field [0001] The invention relates to a high-barrier environment-friendly coated inner lining paper and a manufacturing method thereof, belonging to the technical field of cigarette packaging. technical background [0002] Cigarette lining paper is the paper packed between cigarette sticks and cigarette packs, and its main function is to prevent moisture and preserve fragrance. Cigarette lining papers currently used in the domestic and foreign markets include: 1. Aluminum foil composite lining paper, such as patent application CN1378013A, its production process is simple, and it is mainly made of aluminum foil, base paper and composite glue through composite equipment. Strong resistance, good barrier performance. However, the aluminum foil used is not easy to degrade and recycle, and does not meet the requirements of establishing an environmentally friendly society; 2, aluminum-free coated lining paper, such as patent application CN1888308A, although the lining pa...
