Abstract

The present disclosure relates to thermoplastics film, multi-film structures, and bags including enhanced physical properties. For example, one or more implementations include tailoring the physical properties of thermoplastic films by forming ribs using ring rolling in the films that extend at an angle relative to a direction in which the film is extruded (e.g., the machine direction). In other words, one or more implementations include films with a pattern of ribs extending at an acute angle to the predominate direction of molecular orientation of the thermoplastic film. The angled ribs increase the machine direction tear resistance of the thermoplastic film by intersecting any machine direction propagating tears and redirecting the tears towards the higher tear resistant transverse direction.
