MOISTURE-RETAINING, QUALITY-PRESERVING AND AROMA-KEEPING VACUUM ALUMINUM-PLATED INNER LINER FOR CIGARETTES AND MANUFACTURING PROCESS THEREFOR

摘要

A moisture-retaining, quality-preserving and aroma-keeping vacuum aluminum-plated inner liner for cigarettes, comprising a raw paper layer (1), an upper surface of the raw paper layer (1) being provided with a hot melt sealing layer (3), a water-based sealing layer (4), a vacuum aluminum-plated layer (5) and a water-based protective layer (6), and a lower surface of the raw paper layer (1) being provided with a moisture returning layer (7); and the inner liner further comprises a moisture-retaining and aroma-keeping layer (2) disposed on the upper surface or the lower surface of the raw paper layer (1). During the manufacturing process, the moisture-retaining and aroma-keeping layer (2) may be firstly disposed on the upper surface of the raw paper layer (1), and then the hot melt sealing layer (3), the water-based sealing layer (4), the vacuum aluminum-plated layer (5) and the water-based protective layer (6) are disposed in sequence; and the moisture returning layer (7) is disposed on the lower surface of the raw paper layer (1). Or the hot melt sealing layer (3), the water-based sealing layer (4), the vacuum aluminum-plated layer (5) and the water-based protective layer (6) are disposed in sequence on the upper surface of the raw paper layer (1); and the moisture-retaining and aroma-keeping layer (2) and the moisture returning layer (7) are disposed in sequence on the lower surface of the raw paper layer (1).
