Production method of environment-friendly cigarette packet material

Abstract

The invention relates to a manufacturing method of a packaging material, in particular to a production method of an environment-friendly cigarette packet material. The production method mainly comprises the steps of: A, performing laser die pressing on a BOPP (biaxially-oriented polypropylene) film to form a laser pattern on the BOPP film, B, coating a first layer on the front surface of raw paper, performing flattening treatment on the front surface of the raw paper, coating a second layer on the front surface of the raw paper in a high-temperature pressed environment, performing rolling compounding on the raw paper and the BOPP film, and C, coating a first layer on the back surface of the raw paper and performing flattening treatment on the back surface of the raw paper. The method does not use non-renewable metal aluminum as a raw material any longer, saves non-renewable mineral resources and energy sources, makes full use of a high technology and a new technology to effectively avoid generation of environmental pollutants, raises an environment-friendly grade of a product, saves the resources to the greatest extent, protects an environment, achieves a zero utilization standard of the aluminum, and avoids the generation of three industrial wastes, the product with the higher environment-friendly grade has higher market competitiveness, and the method has wider market prospects.

Description

technical field [0001] The invention relates to a manufacturing method of a packaging material, in particular to a manufacturing method of an environmentally friendly cigarette packaging material for cigarettes. Background technique [0002] The existing transfer paper production process is to coat the aluminum layer on the coated transfer film in a vacuum aluminum coating machine, then apply glue and compound it with ordinary base paper, then peel off the transfer film, and the aluminum layer is glued to the base paper. The effect is transferred to the base paper surface. The characteristic of transfer paper is that it can produce arbitrarily quantitative aluminized paper and cardboard, but the process is complicated, and it will cause the problem of disposal after the transfer film is discarded, resulting in environmental pollution and limited resource conservation. [0003] The annual production capacity of the tobacco industry is 50 million boxes. If all composite alumi...

Problems solved by technology

[0004] CN102134818A is a production method of lining paper developed by our company, which includes the steps of film vacuum aluminum plating, aluminum layer coating, compounding with base paper, and film peeling. Although this method saves metal aluminum and adhesive to a certain extent, The use of glue, but the production process will still consume non-renewable metal aluminum resources and produce a certain degree of waste pollutants. Today, with the continuous improvement of environmental protection requirements, it has gradually been unable to meet production needs.
