Embodiment 1

[0018] A butterfly shadow optically variable BOPP cigarette film, comprising a surface layer and a core layer. The surface layer is wrapped outside the core layer. The core layer includes the following raw materials in parts by weight: 100 parts of optical masterbatch, 15 parts of whitening masterbatch, and 780 parts of olefin and 3 parts of polyalkenate, the surface layer includes the following materials by weight: 12 parts by weight of heat-sealing material, 750 parts of polyolefin, 4 parts of slip agent, 2 parts of antistatic agent, 15 parts of anti-sticking agent and polyolefin 3 parts of acid ester. The optical masterbatch includes calcium carbonate and titanium oxide, and the heat sealing material uses KS409.

[0019] The specific steps of the production process of the butterfly shadow optically variable BOPP cigarette film are as follows:

[0020] Step 1: Weigh the raw materials of the surface layer and the core layer and mix the raw materials of the surface layer and the c...

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...
