Description
Technical field
The invention belongs to cigarette wrapping paper technical field, relate to tobacco lining paper, particularly containing vacuum aluminum-coated internal lining paper and the production method thereof of UV solidified coating.
Background technology
Tobacco lining paper is the paper being lining in the soft box of cigarette or hard box internal layer, and playing moistureproof damp proof effect to cigarette, can prevent cigarette from going mouldy and fragrance loss, is very important cigarette packaging material.
Vacuum aluminum-coated technology is, in high vacuum, high-purity aluminium wire is heated to about 1500 DEG C, and aluminium wire is after fusing, evaporation, and metallic aluminium is attached to the surface of plated film substrate, thus completes film and aluminize.Vacuum aluminum-coated internal lining paper is the product that vacuum aluminum-coated technology is applied in internal lining paper production field, can be divided into vacuum aluminum-coated directly plating papers and vacuum aluminum-coated transferring paper again by production technology difference.
The step that the production technology of vacuum aluminum-coated directly plating papers is general is: aluminium wire is in vacuum environment atomization under 1450 ~ 1500 DEG C of high temperature, aluminium atomic deposition is on paper base material coating layer, form aluminium coated, and be attached on the straight plating body paper of surface coating process equably, be condensed into the aluminium film that one deck is very thin, finally paint, cut.The feature of vacuum aluminum-coated directly plating papers is that production technology is simple, requires higher to the material of body paper.Straight plating body paper uses wood pulp fibre magma to make, and the nontoxic coating layer that surface has layer very level and smooth, the general coating weight of coating layer is at 12 ~ 15g/m
2, smoothness is at more than 800s, and paper density is higher than common body paper.
The general preparation process of vacuum aluminum-coated transferring paper production technology is: in vacuum aluminum-plating machine, metallic aluminium is plated on the transfer membrane of coating process, such as BOPP, PET film etc., gluing and common body paper carry out compound again, then peeled off by transfer membrane, aluminium coated transfers to body paper surface by adhesive effect.Vacuum aluminum-coated transferring paper can produce aluminized paper quantitative arbitrarily, but complex process, transfer membrane needs harmless treatment after finishing using and discarding, and adds cost.
Common liner body paper can produce the adverse consequences such as curling, disconnected paper in primary coat process, produces straight plating internal lining paper at present and generally adopts straight plating body paper as base stock.Because body paper price is higher, the cost ratio transfer paper of directly plating papers will exceed about 15%, and directly plating papers is when bottom-coating heating, drying, and solvent is volatile to be polluted, and consumes energy also higher.Higher production cost has become straight plating internal lining paper and has used the obstacle in extension process.
