preparation example Construction

[0037] like figure 2 Shown: the preparation method of the wear-resisting smoke film that the embodiment of the present invention provides comprises the following steps:

[0038] S101: Weigh the raw materials of the lower surface layer, the middle core layer, and the upper surface layer according to the component ratios of the lower surface layer, the middle core layer, and the upper surface layer, respectively, and mix the lower surface layer, the middle core layer, and the upper surface layer raw materials separately, and the raw materials after mixing are dried;

[0039] S102: the lower surface layer after drying, the middle core layer, and the upper surface layer raw materials are respectively sent into respective extruders for melting, kneading and plasticization;

[0040] S103: Then the molten state melt is sent into the three-layer die head respectively; The melt forms a molten state sheet through the flat die head mouth;

[0041] S104: the sheet is attached to the ch...

Abstract

The invention relates to a wear-resisting cigarette film and a preparation method of the wear-resisting cigarette film. The wear-resisting cigarette film is composed of a lower surface layer prepared from co-polypropylene and anti-sticking agent, a middle core layer prepared from homo-polypropylene, antistatic agent and nucleating agent, and an upper surface layer prepared from co-polypropylene, modified polyacrylate and nucleating agent. The lower surface layer, the middle core layer and the upper surface layer are sequentially stuck to form a composite layer. The lower surface layer is prepared from, by mass, 96-97% of co-polypropylene and 3-4% of anti-sticking agent, the middle core layer is prepared from, by mass, 94-95% of homo-polypropylene, 1.5-5% of antistatic agent and 0.2-0.3% of nucleating agent, and the upper surface layer is prepared from 60-80% of co-polypropylene, 20-40% of modified polyacrylate and 0.4-0.5% of nucleating agent. Wear of the cigarette film in the product transportation process is reduced, and the loss of enterprises is reduced; and the wear resistance is excellent and exceeds that of imported cigarette films.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a wear-resistant flower cigarette film and a preparation method thereof. Background technique [0002] Cigarette packaging film is referred to as cigarette film, which is a kind of BOPP film. As a high-grade BOPP film, cigarette film has lower heat-sealing temperature, better barrier performance, high transparency, and uniform thickness than ordinary packaging films. [0003] The performance of cigarette film has been continuously improved and improved with the demand for cigarette packaging, and the technical requirements such as the appearance and physical indicators of cigarette film have become increasingly homogeneous. Cigarette companies, as the end users of cigarette film, are increasingly using dark and bright pigments in cigarette packaging design to improve and beautify the visual effect of cigarette packaging in order to meet the needs of consu...
