Manufacturing method and structure of embossed release paper

Abstract

The invention relates to a method for manufacturing embossed release paper and its structure. The unwinding machine rolls out the entire roll of sheet-shaped substrate to a rubber-coating wheel, and cooperates with the pressing wheel to evenly coat the surface of the sheet-shaped substrate with a release agent. The excess release agent is then scraped off by a wire bar, and the sheet substrate coated with the release agent is sent to the drying device for colloid drying, and then the sheet substrate is sent to the embossing device for texture heat embossing To form the embossed release paper, and finally the embossed release paper is cooled by the cooling wheel and sent to the coiler to be wound into bundles. The embossed release paper has a sheet substrate, and a first release agent layer is arranged on the surface of the sheet substrate, and the first release agent layer has an embossed texture. The invention produces embossed patterns on the release paper through a single multiple processing, which improves the traditional need for additional secondary processing to emboss the pattern after the release paper is coated with a release agent and rolled into a bundle, so as to reduce the release Paper production time and cost.

Description

technical field [0001] The invention relates to a manufacturing method and structure of a release paper, in particular to a manufacturing method and a structure of a release paper that can produce an embossed pattern through a single process. Background technique [0002] There are three main types of release base paper used in general release paper processing. The first type is glassine paper, which is mainly used for continuous labeling in industry, but its main problem is that it is expensive; and the second type is glassine paper. Film paper (PE laminatedkraft, PEK), that is, single-sided coated paper or kraft paper coated with polyethylene (PE), used as a tape release backing paper, the disadvantage is that it is difficult to disintegrate the discrete pulp and cannot be recycled; the last The second type is clay coated kraft (CCK), which can be made by coating the release agent in the release paper processing factory after coating in the paper mill. This technology can ...

Problems solved by technology

[0004] The traditional production method needs to divide the production of the release paper and the hot embossing pattern into two different procedures, which is easy to cause a waste of production time and personnel, and will increase the production cost virtually. In view of this, the traditional release paper There is a need for improvement and innovation in the way paper is made
