Abstract

The invention discloses a high barrier PET / PP film, which is prepared by adding PP plastic particles and PET plastic particles into a co-extrusion casting film machine, and comprises a PET layer and a PP layer, wherein the PP plastic particles are prepared through blending modification, N,N'-(4,4'-methylenebiphenyl)bismaleimide, methylolpropane trimethyl acrylate, and 4,4'-dihydroxy diphenyl sulfide are added to improve the barrier property, the PET plastic particles are modified through a synthetic modification method, terephthalic acid and ethylene glycol are adopted as base materials, and 2-amino terephthalic acid, 2-nitro-terephthalic acid-4-methyl ester, 1,4-diacetoxybenzene, 1,4-benzenedimethanol, 2,2-dimethyl-1,3-propanediol, 2,3-dibromo-2-butene-1,4-diol, dimethyl 2-bromoterephthalate, 2,2-difluoro-1,3-benzodioxole, and magnesium fluorosilicate are added to adjust the performance. According to the present invention, the PET plastic particles and the PP plastic particles are extruded through the co-extrusion casting cast film machine to prepare the multi-layer casting film, wherein the effects of good high-barrier, fire retardation and bacterial resistance can be achieved through the complementation between the two materials.

Description

technical field [0001] The invention relates to a packaging material, more specifically to a high-barrier PET / PP film. Background technique [0002] High-barrier film is a multi-layered film made by simultaneously extruding a material with strong gas barrier properties and polyolefin with strong thermal seam and moisture barrier properties. [0003] In the prior art, there are other new requirements for high barrier films, especially in some food packaging, there are also some requirements for antibacterial performance and flame retardancy. Especially in the process of long-term use, it will cause a certain aging of the film material, so there is an urgent need for a film material that still has high barrier properties under long-term use conditions, and takes into account flame retardancy and antibacterial properties. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide one. [0005] To achiev...
