Embodiment 1

[0021] Such as figure 1 As shown, a high-barrier double-sided heat-sealed paper towel film is composed of a heat-seal layer 1, a first core layer 2, a second core layer 3, and a corona layer 4, which are sequentially arranged and cast four-layer co-extrusion; The mass percentages of the heat-sealing layer 1, the first core layer 2, the second core layer 3, and the corona layer 4 are respectively: 20%, 31%, 31%, and 18%;

[0022] The material of the heat-sealing layer is composed of binary copolymer (F800E) [binary random polypropylene copolymer], terpolymer (C5608) [terpolymer polypropylene C5608], homopolymer (addition of homopolymer different heat-sealing temperature), antistatic agent (excellent antistatic performance), smooth agent (to ensure its smooth performance, or masterbatch 503P-19), the mass percentage of each raw material is: 25% , 47.5-48%, 24-24.5%, 0.5-1%, 2-2.5%.

[0023] The homopolymer is PP homopolymer (homopolymer PP). The antistatic agent is polyethyle...

Abstract

The invention belongs to the technical field of tissue membranes. A high-barrier double-sided heat-sealable tissue membrane is characterized by consisting of a heat sealing layer, a first core layer, a second core layer and a corona layer which are sequentially arranged in a curtain-coated four-layer co-extrusion mode, wherein the mass percentages of the heat sealing layer, the first core layer, the second core layer and the corona layer are respectively 20%, 31%, 31% and 18%; the heat sealing layer is composed of the following raw materials in percentage by mass: 25% of a binary copolymer, 47.5-48% of a ternary copolymer, 24%-24.5% of a homopolymerization material, 0.5%-1% of an antistatic agent and 2%-2.5% of a slipping agent; and the corona layer is made from a binary copolymer or a ternary copolymer. The tissue membrane disclosed by the invention can be subjected to double-sided heat-sealing, and can conform to different heat sealing modes (applicable to the packaging of different paper products) of paper products.

Description

technical field [0001] The invention belongs to the technical field of tissue films, and in particular relates to a high-barrier double-sided heat-sealed tissue film and a preparation method thereof. Background technique [0002] At present, there is no paper towel film suitable for different paper product packaging (toilet paper, facial tissue, napkin and wet tissue packaging, etc.). Contents of the invention [0003] The purpose of the present invention is to provide a high-barrier double-sided heat-sealing paper towel film and its preparation method. The paper towel film prepared by this method can be heat-sealed on both sides, which can meet different heat-sealing methods of paper products (suitable for different paper product packaging) . [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a high-barrier double-sided heat-sealing tissue film, which is characterized in that it consists of a heat-sealing layer, a f...
