Composite lining paper coating, printing processing technology

Abstract

The invention discloses a composite lining paper coating, printing and processing technology. The technology comprises the following specific steps of: (1) unwinding: respectively inserting an aluminum foil roll and lining paper into two unwinding devices, simultaneously unwinding the aluminum foil and lining paper, enabling the unwound aluminum foil and lining paper to be parallel to each other,enabling the aluminum foil to be positioned right above the lining paper, and (2) compounding: coating the opposite surfaces of the aluminum foil and the lining paper with an adhesive through an adhesive coating roller, and then simultaneously pressing and forming the aluminum foil and the lining paper coated with the adhesive through a composite pressing roller to obtain the composite lining paper. The printing roller is set to be a micro-concave screen roller; the paper feeding direction of the composite lining paper is opposite to the rotating direction of the micro-concave screen roller; the composite lining paper and the micro-concave screen roller are coated reversely, certain relative friction is generated, so that uniform spreading of coating liquid on the composite lining paper isfacilitated; the liquid transfer amount of the micro-concave screen roller is further large, ink can fully fill fiber gaps and subsurface concave-convex areas of the composite lining paper, and the coating effect of the composite lining paper is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lining paper production technology, in particular to a composite lining paper coating printing process. Background technique [0002] The inner lining paper is the inner wrapping paper in the packaging box, mostly made of aluminum thin paper. The inner lining paper is necessary to prevent the wrapping paper from wrinkling, that is, the wrapping paper has a tendency to recover when there are wrinkles. The inner lining paper for cigarettes is The inner lining and the wrapping paper of the inner layer of the cigarette soft box or hard box are an important type of cigarette packaging materials. For a long time, the inner lining paper products covered with aluminum layer are commonly used in cigarette packaging. The main types are composite aluminum foil inner Lining paper, composite transfer lining paper, vacuum direct aluminized lining paper and transfer vacuum aluminized lining paper, etc. Among them, compo...

Problems solved by technology

[0003] The existing composite lining paper coating and printing processing technology uses one-time heating and drying for lamination, coating and printing, resulting in poor drying effect. Secondly, the traditional printing roller is used to print the composite lining paper , the ink cannot be evenly spread on the composite lining paper, which affects its printing effect, so it cannot meet the needs of users
