Abstract

The invention relates to a preparation method of an anti-stripping packing material. The preparation method of the anti-stripping packing material comprises the following steps of firstly, taking polyamide fiber, poly-p-benzamide fiber, succinimid and polyisobutene, putting the polyamide fiber, the poly-p-benzamide fiber, the succinimide and the polyisobutene into a reaction tank, and keeping the temperature constant for the reaction; secondly, taking a high polymer material mixture out of the reaction tank after the reaction, and performing double-screw extrusion to extrude out the high polymer material mixture through double screws; thirdly, performing thermal rolling on the extruded high polymer material mixture and enabling a mixed material to form a film through rolling; fourthly, performing thermal compression bonding on the mixed film material obtained in the third step and polypropylene; fifthly, performing natural cooling after the thermal compression bonding so as to obtain the anti-stripping packing material.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a preparation method of a packaging material, in particular to a preparation method of an anti-peeling packaging material. Background technique [0002] During the use of film packaging materials, the anti-peeling performance, retort resistance performance and puncture resistance performance of film packaging materials are very important. The anti-stripping performance is too poor. During use, when an external force is encountered, the interaction between the composite layers will be reduced, resulting in the separation of the composite layers. Under normal circumstances, some composite layers are bonded by adhesives, and some composite layers are bonded by hot pressing at high temperature. [0003] Conventional composite-layer film packaging materials have low peel strength, which cannot satisfy practical applications. Therefore, we need to change the preparation process of the ...
