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...
Embodiment 2
[0025] 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, and the core layer includes the following raw materials by weight: 108 parts of optical masterbatch, 3 parts of antistatic agent, whitening 24 parts of masterbatch, 801 parts of polyolefin and 4.5 parts of polyalkene ester. The surface layer includes the following materials by weight: 18 parts of heat-sealing material, 785 parts of polyolefin, 7 parts of slip agent, 1 part of antistatic agent, anti-sticking 36 parts of agent and 5 parts of polyacrylate. The polyolefin in the surface layer is a mixture of polypropylene random binary copolymer and random terpolymer, and the polyolefin in the core layer is homopolyolefin.
