Film used for butterfly optical variability BOPP (Biaxially-oriented Polypropylene) cigarette, and production technology thereof

Abstract

The invention discloses a film used for a butterfly optical variability BOPP (Biaxially-oriented Polypropylene) cigarette, and a production technology thereof. The film comprises a surface layer and acore layer, wherein the surface layer covers the out of the core layer; the core layer is prepared from the following raw materials in parts by weight: 100-120 parts of optical master batch, 0-5 parts of antistatic agent, 0-49 parts of whitening master batch, 780-820 parts of polyolefin and 3-6 parts of polyolefin acid ester; the surface layer is prepared from the following raw materials in partsby weight: 12-20 parts of heat-seal raw materials, 750-810 parts of polyolefin, 4-8 parts of slipping agent, 0-5 parts of antistatic agent, 8-45 parts of anti-sticking agent and 3-6 parts of polyolefin acid ester. The product has the advantages of reasonable product design and simple structure and production technology, the obstruction effect of a film used for the BOPP cigarette for moisture andsmell can be kept, in addition, the appearance effect of the cigarette is improved, and therefore, the outer package of the cigarette has a better grade feeling.

Description

Technical field [0001] The invention relates to the technical field of films, in particular to a butterfly shadow light-changing BOPP cigarette film. Background technique [0002] Cigarettes are a type of tobacco products. The production method is to dry the tobacco and cut into shreds, and then use a paper roll to grow about 120mm and 10mm in diameter as a barrel-shaped strip. When smoking, one end is lit, and the other end is used to inhale the smoke produced by the mouth. Cigarettes are usually packaged in cigarette film, which is the abbreviation of BOPP cigarette film, also known as biaxially oriented polypropylene cigarette film, which is co-extruded and stretched from a variety of polypropylene functional materials. At present, domestic manufacturers generally use three-layer co-extrusion technology to produce high-performance BOPP cigarette films by biaxial stretching, which has high transparency and gloss, non-toxic materials, stable molecular structure, and has a certa...

Problems solved by technology

At present, the main structure and process of BOPP cigarette films commonly used in the market are mostly cut and packaged with transparent films. Although the use requirements of cigarette films are met, the appearance of cigarettes is not good.
