发明名称 METHOD FOR THE PRODUCTION OF MULTILAYER FILM FOR PACKAGINGS AND FILM PRODUCED BY SAID METHOD
摘要 The method, herein disclosed, for forming a multilayer film for packages, which is particularly resistant to tears and/or rips, provides to couple one or more extensible films to one or more films having a strongly reduced or almost null extensibility. Optionally, the invention provides to devide at least one extensible film in two or more longitudinal strips, which are stretched before being coupled to one or more extensible films having a width equal to the initial one of said extensible film apt to be stretched. The multilayer film, thus obtained, is further on cut, in the way corresponding to the previous subdivision, in symmetric strips, the width of which is slightly greater than that of the corresponding stretched reinforcement strip.
