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.

A reinforced multilayer material includes a mesh material covered on at least one side, and possibly both, by a layer of a resinous film material. The mesh material includes filaments that intersect one another, at least some of the filaments being composite filaments having a carrier portion of a relatively high melting point and a bonding portion of a relatively low melting point, the bonding portion of each composite filament being thermally bonded to other filaments at least some points of intersection. The multilayer material has a mass per unit area of less than 9.0 oz/yd.sup.2 and at least one of a) a bursting strength to mass per unit area ratio of at least 9.0 lbs./(oz/yd.sup.2), where bursting strength is measured in accordance with ASTM-D37 86 and b) a breaking elongation of at least 5% in the warp direction when breaking elongation is measured in accordance with ASTM-5034. A bag is provided that is made at least in part from a multilayer material having at least some of the characteristics described above.

An impact-resistant film comprises at least one layer of an elastomeric polymer material and an adhesive layer.

Disclosed is a multilayer film structure, comprising, in order, a puncture resistant layer comprising at least one cyclic olefin copolymer (COC) and at least one ionomer or polyolefin, a tie layer and a sealant layer. The structure can be coextruded and can be prepared using a triple bubble process.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
