patent name vinylidene chloride polymer composition and food packaging made from it patent applicant Dow global technology company main applicant address Michigan inventor e · K · Li; R. kleinier application (patent) No Help customers get the most effective processing technology for our materials 6 application date 2003.10.14 certification date approval Announcement No. approval announcement date 2005.12.14 instruction CD No. d0550 main sub pilot construction will help to improve the demand for products that meet the climatic conditions and traffic loads class No. c08l27/08 class No. c08l27/08; B32B27/32； C08J5/18； B65d65/40 division original application No. priority item 2002.10.24 us 60/421029 abstract the invention relates to a poly (vinylidene chloride) copolymer composition, which contains (1) α The content of the copolymer of olefin and unsaturated alkyl carboxylate, and (2) vinylidene chloride and vinyl chloride can effectively improve the meat adhesion of food packaging made of the copolymer composition containing the copolymer (hereinafter referred to as the effective amount) compared with the composition in which the proportion of each component is the same as that of the copolymer composition but the copolymer is not added. Preferably, the copolymer contains ethylene and at least one alkyl ester of unsaturated carboxylic acid. The invention also relates to a method for preparing thermoplastic food packaging, which comprises α Copolymers of olefins and unsaturated alkyl carboxylates are added to the copolymers of vinylidene chloride and vinyl chloride to improve the meat adhesion of food packaging. In addition, the invention relates to a kind of copolymer containing vinylidene chloride and vinyl chloride and an effective amount of α Film of copolymers of olefins and unsaturated alkyl carboxylates. The film is preferably used in applications in contact with meat. In addition, the invention relates to a kind of copolymer containing vinylidene chloride and vinyl chloride and an effective amount of α A combination of a film of a copolymer of olefins and alkyl unsaturated carboxylates and fatty substances (preferably fatty meat, fatty meat products, or other fatty foods) adjacent to or in contact with it. On the other hand, the invention relates to a package for meat or other fatty substances, which contains an copolymer of vinylidene chloride and vinyl chloride and an effective amount of α A copolymer of olefins and alkyl esters of unsaturated carboxylic acids, in which the package is designed to bring vinylidene chloride copolymers into contact with meat or fatty substances. On the other hand, the invention relates to a casing containing a film containing an copolymer of vinylidene chloride and vinyl chloride and an effective amount of α Copolymers of olefins and alkyl esters of unsaturated carboxylic acids. In yet another aspect, the present invention relates to an interpolymer containing vinylidene chloride and vinyl chloride and an effective amount of α The application of vinylidene chloride copolymer composition of at least one copolymer of olefin and alkene bonded unsaturated carboxylic acid alkyl ester in composition suitable for manufacturing film, film, molding, packaging (in each case, preferably suitable for contacting or containing fatty substances or food), preferably in casings. Sovereignty item 1 A poly (vinylidene chloride) interpolymer composition, which contains (some will be many times higher 1) α The content of the copolymer of olefin and unsaturated alkyl carboxylate, and (2) vinylidene chloride and vinyl chloride can effectively improve the meat adhesion of food packaging made of the copolymer composition containing the copolymer (hereinafter referred to as the effective amount) compared with the composition with the same proportion of components as the copolymer composition but without adding the copolymer.
