A kind of packaging plastic substrate film containing fumarate

Abstract

The invention discloses a package-purposed plastic-based film containing fumaric acid. The package-purposed plastic-based film is prepared form the following raw materials in parts by weight: 35-40 parts of polytetrafluoroethylene, 35-40 parts of LDPE (Low-Density Polyethylene), 13-16 parts of SG-1 type polyvinyl chloride, 3.8-5.6 parts of epoxidized soybean oil, 2.5-3.7 parts of polyethylene wax powder, 0.8-1.2 parts of distearoyl isopropoxy aluminate, 7.8-10.8 parts of kieselguhr, 1-2 parts of polyisobutene, 1-2 parts of poly-4-methyl-1-amylene, 1-2 parts of modified bentonite, 1.6-1.9 parts of antioxidant 1010, 1-2 parts of triethyl acetyl citrate, 0.7-1.3 parts of fumarate, 0.8-1.6 parts of zinc stearate, 1-2 parts of N-2-(aminoethyl)-3-aminopropyl trimethoxy silane, 0.9-1.8 parts of dicyclopentadienyl iron and 0.4-0.8 part of modified nano sepiolite powder. The package-purposed plastic-based film has good barrier property, gas tightness, pressure resistance and impact resistance and has the characteristics of high heat seal strength and good heat seal property.

Problems solved by technology

Single-layer polyethylene film has poor barrier properties to oxygen and other gases. When packaging fried foods and other foods, it is easy to cause contamination at the seal. General liquid packaging polyethylene film has poor sealing performance for this type of packaging and cannot meet the packaging process and requirements. The requirements for the storage period of packaging items, so it is necessary to use multi-layer polyethylene modified film or composite film with good barrier performance and inclusion sealing performance
