More Information
Summary:Flexible film (10) for packaging comprising, joined together, a first layer (4), a second layer (6) configured to provide a barrier through the film (10) with respect to moisture, gases and/or light, a fourth layer (12), configured to promote a substantially linear tearing of the film (10) and comprising polyolefins crystallised in a linear fashion, and a protective layer (14) comprising a thermoplastic polymer, covering at least part of the fourth layer (12) in order to prevent/limit the migration of fatty or oily substances through its thickness, towards the fourth layer (12). The invention also relates to an easy-opening bag, at least partially made from such film.
