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

Abstract

The invention discloses a package-purposed plastic-based film containing itaconate. The package-purposed plastic-based film is prepared from the following raw materials in parts by weight: 20-25 parts of homogenous ethylene / alpha olefin copolymer, 45-50 parts of LDPE (Low-Density Polyethylene), 10-15 parts of SG-1 type polyvinyl chloride, 3-5 parts of epoxidized linseed oil, 2-3 parts of polyethlene wax powder, 1.5-2.5 parts of distearoyl isopropoxy aluminate, 8-12 parts of kieselguhr, 0.5-1 part of polyisobutene, 0.8-1.5 parts of poly-4-methyl-1-amylene, 1.5-3 parts of modified limestone powder, 2-3 parts of 4,4-methlene(2,6-di-tert-butylphenol), 0.7-1.4 parts of triethyl citrate, 0.5-1 part of itaconate, 0.8-1.6 parts of calcium stearate, 1.2-2.6 parts of anilino-methyl-triethoxysilane, 0.3-0.7 part of dicyclopentadienyl iron and 1.5-2.4 parts of modified smectite 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.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a packaging plastic substrate film containing itaconate. Background technique [0002] my country is a big packaging manufacturing and consuming country in the world.
