Improved structures of polymers made from single site catalysts

(57) the copolymer of the ethylene and the alpha olefin which were generated by the polymerization reaction under existence of a 1 part catalyst like summary metallocene, the inside of the multilayer film which molecular orientation is carried out and contains the irradiated heat contraction nature film (12, 14, 16) as a film -- much more -- it is used by carrying out. The new blend with this copolymer and other polymer materials is indicated -- and the inside of the film as a film, and the heat contraction nature film by which molecular orientation was carried out especially -- much more -- it is used by carrying out. The bag made from the multilayer film is useful especially although the shrink package of the important piece of meat is carried out. The packaging material made from the method for forming a flexible film and it is also indicated.
