Abstract:
Methods of enhancing one or more physical properties of a thermoplastic film include incrementally stretching thermoplastic films in the machine direction and/or transverse direction. In one or more implementations, methods of incrementally stretching thermoplastic films include reducing the gauge of the films while maintaining or increasing a ratio of the machine direction to transverse direction resistance to tear. The methods can involve cold stretching the films and imparting rib patterns into the film. The linear ribs can have alternating thick and thin gauges.

Abstract:
An activatable wrap material includes a film material a first side and a second side opposite the first side. The wrap material includes a plurality of protrusions extending outward from the first side of the wrap material and oriented in a pattern across the first side of the wrap material and a plurality of planar portions defined within the first side of the wrap material and throughout the plurality of protrusions. The wrap material exhibits an average peel adhesion force, when activated against a surface, between about 1.50 g/in to about 3.25 g/in. The wrap material further exhibits an average roll unwind force, when wound on a roll, between about 1.50 g/in to about 5.0 g/in. The wrap material also exhibits an average blocking force, when contacting itself, between about 0.4 g/in2 to about 1.30 g/in2.
