PROCESS OF OBTAINING A BIO-ORIENTED FILM, CO-EXTRUDED, AND OF LOW THICKNESS MADE BY A THREE BUBBLE PROCESS THAT AT THE TIME OF BEING THERMOFORMED PROVIDES A UNIFORM THICKNESS IN THE PRODUCED TRAY

摘要

The present invention relates to provides a double-oriented film, co-extrude, and of low thickness, with a layered composition that gives the property of being of high barrier to gases and manufactured by the process of co-extrusion of 3 bubbles, which gives the property of when being thermoformed, ensure the distribution of uniform thickness in the walls, base, folds, and corners of the formed tray saving a minimum of 50% of plastic without diminishing its gas barrier and its resistance to puncture.
