ALUMINUM-FREE CIGARETTE LINING PAPER CAPABLE OF KEEPING HUMIDITY CONSTANT AND PRESERVING QUALITY AND AROMA, AND MANUFACTURING PROCESS THEREFOR

摘要

An aluminum-free cigarette lining paper capable of keeping humidity constant and preserving quality and aroma, comprising: a base paper layer (1), the upper surface of the base paper layer (1) being further sequentially provided, from inside to outside, with a hot melt sealing layer (3), a waterborne sealing layer (4), a waterborne printing layer (5), and a waterborne protection layer (6), the lower surface of the base paper layer (1) being provided with a humidity restoration layer (7); the cigarette lining paper further comprises a humidity-and-aroma preserving layer (2) provided on the upper surface or the lower surface of the base paper layer (1); the humidity-and-aroma preserving layer (2) is provided between the base paper layer (1) and the hot melt sealing layer (3), or the humidity-and-aroma preserving layer (2) is provided between the base paper layer (1) and the humidity restoration layer (7). In addition, a manufacturing process for the aluminum-free cigarette lining paper capable of keeping humidity constant and preserving quality and aroma is provided. By providing the humidity-and-aroma preserving layer (2), the aluminum-free cigarette lining paper can effectively balance humidity of a cigarette product, remaining quality of the cigarette product.
