POLYMER COMPOSITION FOR PRODUCTION OF POLYMERIC FILMS USED IN AGRICULTURE AND MANUFACTURING METHOD OF FILM, FILM THEREOF

A polymer composition for production of polymeric films used in agriculture is provided to effectively accelerate plant growth and convert UV rays into red visible spectrum rays. A polymer composition for production of polymeric films used in agriculture comprises polyethylene and active additives therein. The content of active additives is a range of 0.005-5.0%. The active additive contains: a compound(A) selected from the group consisting of europium oxide, europium organic salts and europium inorganic salts; a compound(B) selected from the group consisting of metal oxide belonging to element groups with f electron shell, metal organic salts belonging to element groups with f electron shell and metal inorganic salts belonging to element groups with f electron shell; a compound(C) selected among groups belonging to beta-diketones; a compound(D) selected from the group consisting of bidentate ligand nitrogen heterocycle and phosphine oxide wherein alkyl or phenyl is substituted; and a compound(E) selected from the organic group consisting of biphenyl, p-terphenyl, diphenyloxazole and fluorene, which absorb UV rays and transmit the absorbed energy to the compound(C) or (D).
