摘要

b foil polimerica of mu00e9ltiplas layers biaxially oriented film polimerica, film shrunk polimerica foil polimerica of mu00e9ltiplas layers co extruded and composiu00c7ao of Materia d compositions of polymer, films of individual film layer and multiple layers. Where the composition and / or a layer of a film has a base polymer or amorphous nylon or EVOH.And a component of semi crystalline nylon modified. Where the base polymer is amorphous nylon, the nylon modified composition includes a first nylon with relatively lower melting temperature, and typically a second nylon with relatively lower melting temperature, and typically a nylon with the melting temperature for MA IOR.Where the polu00edmerobase is EVOH, the composition of semi crystalline nylon modified can optionally be defined completely by the nylon with relatively lower melting temperature, which has a melting temperature lower than 170 198 C.Mixtures of quantities of amorphous nylon or EVOH with revealed the component of semi crystalline nylon can be used with the component of semi crystalline nylon can be used to produce films which can be uniaxialmente oriented or biaxially oriented to provide capacity Es of shrinkage of at least 28%, and up to about 57% or more.
