Abstract

The invention discloses a processing technology of PE (polyethylene) coated paper and a processing technology of release paper, which are performed by the following steps: directly coating polyolefin emulsion on base paper by a coating machine, and then drying to obtain the PE coated paper. The processing technology of release paper is characterized by further coating a release agent based on the PE coated paper and then drying to obtain the release paper, thereby omitting the traditional extruder, saving the investment in expensive equipment, and avoiding the problem of high energy consumption resulting from the use of the extruder; as the polyolefin emulsion coating mode based on the coating machine can save more polyolefin and the polyolefin film formed thereby can be thinner, PE coated paper having lighter weight can be produced, and more kinds of light-weight composite paper (for example, release paper having lighter weight) can be produced based on the PE coated paper having lighter weight, thereby expanding the application range of the product. In conclusion, the processing technologies disclosed by the invention not only can save cost and reduce energy consumption, but also can enable the product to have better market adaptability and competitiveness.

Description

technical field [0001] The invention relates to a processing technology of composite paper, in particular to a processing technology of coated paper and a processing technology of release paper based on the processing technology of coated paper. Background technique [0002] Laminated paper is a composite paper that uses paper as a substrate and adopts a special process to attach PE (polyethylene) and PP (polypropylene) plastics to it. Generally used for waterproof and leak-proof food containers, wrapping paper and various moisture-proof papers. Polyolefin (including PE and PP) coated paper in coated paper is widely used because of its good anti-adhesive and moisture-proof properties. The traditional processing technology of polyolefin coated paper is generally to use extruder to melt polyolefin particles at high temperature and extrude them on the backing paper to form a coating. The weight of the coating generally ranges from 20 grams to 25 grams per square meter. , depe...
