Moisture-retaining, quality-preserving and fragrance-retaining inner liners for vacuum aluminum-deposited cigarettes and manufacturing process thereof

摘要

The moisture-retaining, quality-preserving and fragrance-retaining vacuum aluminium-plated inner liner for cigarettes comprises a green paper layer ( 1 ), on the upper surface of which the green paper layer ( 1 ) has 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) are provided; The lower surface of the raw paper layer 1 is provided with a moisture returning layer 7 ; The inner liner further comprises a moisture-retaining and fragrance-retaining layer (2) disposed on the lower surface or the upper surface of the raw paper layer (1). During the manufacturing process, a moisture-retaining and fragrance-retaining layer (2) may first be disposed on the upper surface of the raw paper layer (1), then 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 are sequentially disposed; and a moisture return layer 7 is disposed on the lower surface of the raw paper layer 1 . Alternatively, 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) are sequentially disposed on the upper surface of the raw paper layer (1); And the moisture-retaining and fragrance-retaining layer (2) and the moisture returning layer (7) are sequentially disposed on the lower surface of the raw paper layer (1).
