Problems solved by technology

When packaging packages with high temperature oil pollution in daily life, the high barrier film cannot be well sealed according to the package, and it is often placed for a long time during the processing process. After a long period of storage, High-temperature packaging causes shrinkage and damage of materials, resulting in waste of materials. At the same time, it is impossible to ventilate the high-temperature oil-stained packaging, which will cause damage to the packaging, and the packaging film will lose its shape during the lifting process. The packaging is antibacterially protected, and after a long period of storage, the organic matter in the oil stains will adhere to the film. When the oil stains are treated, there will be a large amount of oil stains on the film, so the film has to be disposed of. fall off, causing the film to be unrecyclable

Abstract

The invention discloses an oil-pollution-resistant heat-sealing high-barrier thin film. The structure of the oil-pollution-resistant heat-sealing high-barrier thin film is PA1/T1/PP/T2/PA2/C/PA3/T3/PE1/PE2/PE3. The PE3 is an outer layer in contact with the outside during packaging. The PA1 is an inner layer in contact with a packaged object during packaging. The PP material is an auxiliary layer,and the C is a gas barrier layer. The T1, T2 and T3 are adhesive layers, the PA1, PA2 and PA3 are oil-pollution-resistant layers, and the PE1, PE2 and PE3 are heat-sealing high barrier layers. The auxiliary layer, the gas barrier layer, the adhesive layers and the oil-pollution-resistant layers are separately subjected to pretreatment to obtain pre-crystalline materials, and the pre-crystalline materials are subjected to transverse and longitudinal stretching, corona, static electricity removal, curing and winding treatment by a twin-screw extruder to obtain the high-barrier thin film. In a word, according to the process structure of the oil-pollution-resistant heat-sealing high-barrier thin film, the adhered oil pollution can be cleaned away, the influence of high temperature on the high-barrier thin film is prevented, and good bending strength is achieved; and the high-barrier thin film is subjected to sealing treatment, the structure is reasonable, and the recovery is facilitated.

Description

technical field [0001] The invention belongs to the technical field of packaging materials and specifically designs an oil-pollution-resistant heat-sealing high-resistance barrier film. Background technique [0002] With the rapid development of industrialization, high-barrier plastic packaging film is one of the fastest-growing functional films at present. High-barrier film refers to protecting the contents of the package. Strong polyolefin is extruded at the same time, and it is a film with a multi-layer structure. It is also a packaging film that prevents the contents of the package from seeping out. The high barrier property of the high barrier film refers to the high barrier property of the high barrier film means that under the standard state of 23 ℃ and 65% relative humidity, the permeation rate of oxygen is less than 5ml / m2 day, and the permeation rate of water vapor is less than 2g / m2·d. [0003] The packaging material industry is a large industry integrating mult...
