Embodiment 1

[0011] Embodiment 1 of the present invention: the preparation method of tobacco packing box film, at first polyvinyl alcohol is dissolved in the mixture of water and alcohol, forms polyvinyl alcohol solution; Set up the unsealing line, then use the mechanical arm to clamp the tobacco packaging box, spray polyvinyl alcohol solution on the six sides of the tobacco packaging box and make it evenly sizing, after spraying, send the cigarette box into the blower box for drying, and it is completed Preparation of Tobacco Packaging Films.

Embodiment 2

[0012] Embodiment 2 of the present invention: the preparation method of the tobacco packaging box film, first heat the high-density polyethylene to 200 ° C, and set the unsealing line at the opening of the trademark paper of the cigarette packaged tobacco packaging box in a circular direction, and then clamp it with a mechanical arm Hold the tobacco packaging box, scrape-coat the six sides of the tobacco packaging box and make it evenly sizing, and cool the tobacco packaging box to form a film after scraping coating, that is, the preparation of the tobacco packaging box film is completed.

Abstract

The invention discloses a manufacturing method of cigarette packaging box films. According to the method, polymer uniformly coats the outer surface of a cigarette packaging box in a spraying, blade coating or infiltrating manner, no seams are generated on the whole formed films, the good sealing effect is possessed, and the manner is simple, easy to implement and low in cost.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for preparing tobacco packaging film. Background technique [0002] Cigarettes are a daily commodity. The shredded tobacco in cigarettes must maintain a certain amount of moisture so that the taste can be stable. The change of moisture in shredded tobacco has a great influence on smoking taste, so how to prevent moisture and keep moist of cigarettes has always been an important issue in the tobacco industry. Existing cigarette packages are respectively from the inside to the outside: cigarettes, inner lining paper (aluminum foil paper), trademark paper (packaging outer box), and transparent paper (BOPP film). The measures taken in the moisture-proof and moisturizing aspects of cigarettes are to pack the cigarettes with aluminum foil paper, put them in the outer box of the package, and seal them with BOPP film to prevent the loss of moisture and the sealing ef...
