ã€Abstracts】 The present invention relates to a co-extruded heat-sealable biaxially oriented polypropylene antifogging packaging film. The preparation method comprises the following steps: 1) adding 0.1 to 1% of a polymethyl methacrylate elastomer and 0.1 to 1% of silicone having a particle size of not more than 2 μm to the raw material of the film surface layer; The core raw material is added with 0.1% to 1% of the total weight of the ethoxylated amine. 3) The surface of the film is passivated with O#-[3] or/and high-speed ionized ions. The present invention has the advantages of reducing or eliminating the water fog phenomenon between the cigarette pack and the cigarette packaging film, and improving the package aesthetics of the pack.
ã€Sovereign Items】 1. A method for manufacturing a co-extruded heat-sealable biaxially oriented polypropylene antifogging wrapping film, characterized in that the method of preparation is: 1) Adding 0.1 to the total weight of the raw materials in the surface layer of the film. 1% of polymethyl methacrylate elastomer and 0.1 to 1% of silicon dioxide having a particle size of not more than 2 μm; 2) adding 0.1 to 1% of ethoxylated amine to the raw material of the thin film core; 3) Passivate the film surface with O3 or/and high-speed ionized ions.
