Patent Name Applicant Yu Zhiwen's main applicant Address 201203, Room 503, No. 20, Lane 200, Xiangnan Road, Zhangjiang, Pudong New Area, Shanghai 201203 Inventor Yu Zhiwen Application (patent) No. 200410017159.0 Application date 2004.03.24 Certification date Approval announcement No. 1673264 Approval announcement date 2005.09.28 Manual CD No. D0539 Main classification No. C08L23/04 No. C08L23/04; C08K5/54; B29C70/58 No. Original application No. Summary of the Invention The present invention is a method for preparing a plastic material for the packaging of water-cream-based creamy material hoses, including the selection and processing of materials, characterized in that: A) the material uses polyethylene resin and ethylene-vinyl alcohol Copolymer; B) The extrusion calender is used to form a sheet at one time to form a microscopic laminar composite structure. The material also contains plastic masterbatches of the desired color. Ethylene-vinyl acetate copolymer impact modifiers can be added to the material. Photosensitizers can be added to the material. The material also contains modified composite materials. The invention has the advantages that the microscopic laminar composite structure of the packaging material meets the needs of packaging of emulsion materials with water-based cream, and the one-step method is adopted for material processing, and the operation is simple and feasible. No special processing equipment is needed, and the product can be degraded and can also be recycled. There is no environmental pollution, in line with national environmental protection policies and sustainable development. Sovereignty item 1. A method for preparing a plastic material for packaging a hydrogel-based creamy material hose, including a method for selecting and processing a material, characterized in that: A) the material is a polyethylene resin and an ethylene-vinyl alcohol copolymer ; B) The extrusion calender is used to form a sheet at one time to form a microscopic layered composite structure sheet.
