摘要

Extendable polyolefin film obtainable by joining two or more coextruded polyolefin layers and method for obtaining them. The present invention relates to an expandable polyolefin film obtainable by joining two or more co-extruded layers that can be perforated up to 70% of its surface without losing its mechanical strength properties. This film can be used in various sectors or jobs, such as securing loads on pallets or packaging perishable products, which due to their characteristics need ventilation or evacuation of temperatures, such as plants, flowers, fruits or vegetables. Another object of the present invention is a method for obtaining an expandable polyolefin film characterized in that it comprises joining two or more layers of polyolefin film co-extruded in opposite directions, in the direction of their natural force.
