Abstract

The invention relates to a preparation method of a macromolecule packaging material. The preparation method comprises the following steps: (1) opening a reaction kettle, adding alkyd resin, polychloroprene and polycarbonate into the reaction kettle, heating and mixing until the mixture is mixed uniformly; (2) after temperature preservation, increasing the temperature of the reaction kettle, then adding cycloheptene, cellulose acetate butyrate, ethylene glycol, silicon dioxide and butyl rubber after temperature stabilization, then mixing again until all components are dispersed uniformly, thereby obtaining the uniform mixed packaging material; (3) then carrying out extrusion molding on the mixed packaging material; (4) cooling the extruded material, arranging the material rapidly at 3-6 DEG C, and cooling; (5) after cooling, heating the macromolecule packaging material to be 130 DEG C, and stretching after temperature preservation; and (6) packaging the packaging material so as to obtain the prepared macromolecule packaging material.

Description

technical field [0001] The invention relates to a preparation method of a packaging material, in particular to a preparation method of a polymer packaging material. Background technique [0002] There are many applications of polymer packaging materials, and they are widely used in food, medicine, parts, etc. The barrier properties of packaging materials have a more prominent effect on the use of packaging materials. The barrier property is poor. After a long time of storage, the substances in the packaging material will seep out, or the small molecular substances from the outside can enter the inside of the packaging material, which will greatly restrict the use of packaging materials. In addition to barrier properties, polymer packaging materials also need to have good retort resistance, which can improve the performance of polymer packaging materials. Contents of the invention [0003] Technical problems to be solved: ordinary polymer packaging materials have poor bar...
