Abstract
The invention relates to a processing method of a PE (polyethylene) easy-to-tear high-barrier composite foam film. The processing method is characterized in that the composite foam film comprises PET (polyethylene terephthalate) 12/PE 147/PE 45/PET 12/AL (aluminum) 20/PE 45. The processing method is completed by five steps, namely (1) pre-compounding PET 12 and PE 147; (2) pre-compounding PET 12 and AL 12; (3) pre-compounding a PET 12/AL 20 composite material and PE 45; (4) compounding a PET 12 and PE 147 composite material and a PET 12/AL 20/PE 45 composite material; and (5) cutting into bundles. The processing method has the beneficial effects that the PE easy-to-tear high-barrier composite foam film improves the strength of a film body and overcomes the defects of poor ductibility, easiness in tearing, easiness in fracture during folding and the like of a traditional product. The hardness of the film body is further improved, the film body further has the performance of adapting to external temperature, humidity and other environmental conditions, and the product has good gas barrier and water barrier performances.
Description
Technical field
The present invention relates to a kind of high isolation compound packaging film, especially relate to the processing method of the composite foamed film of a kind of PE easy-tear type high-barrier.
Background technology
A few days ago, the transparency of the composite foamed film of existing PE, glossiness, mechanical strength, retractility, wearability, cold resistance and surface strength etc. are all undesirable.Moreover aluminium foil layer is metal forming class unique in current composite foamed film packaging material, the obstruct protective values such as it blocks water, choke, shading are that other packaging material are difficult to be equal to.But the ductility of general aluminium foil is not good, thickness is very low, folding time easy fracture, the weight ratio of unit are is heavier, thus easily produces the self performance defects such as eyelet, causes it to intercept protective value undesirable.
Summary of the invention
The object of this invention is to provide a kind of manufacture method of high-barrier agricultural chemicals level composite package film, solve that existing PE easy-tear type high-barrier composite foamed film ductility is not good, thickness is low, weight per unit area is heavier, tear and get inconvenient problem.
The technical solution adopted for the present invention to solve the technical problems is:
A processing method for the composite foamed film of PE easy-tear type high-barrier, is characterized in that, this composite foamed film is by PET
