A heat-shrinkable film comprises a blend of 35-75 wt % of an ethylene-based polymer, 10-45 wt % of an ethylene/unsaturated ester copolymer, and 5-30 wt % of a plastomer, with the blend making up at least 20 wt % of the film. The ethylene-based polymer has a peak melt point ≥95° C. The plastomer has a peak melt point ≤90° C. and a melt index of ≤1.1 g/10 min. The film comprises a cross-linked polymer network which has been strained by solid state orientation. The film has a total free shrink at 85° C. of at least 90% and an energy-to-break of at least 0.70 J/mil.

A system and method for manufacturing erosion control filter socks consists of a mass of filtering material, a material supply assembly, an assembly section, and a packaging section. Switchgrass is used as the filtering material. Upon receiving the mass of filtering material, the material supply assembly appropriately transfers the filtering material to the assembly section. The filtering material is loaded into a receiving sock with the use of a sizing funnel in the assembly section to create a filter sock. The density of the filtering material within the filter sock varies. When loading is complete, the packaging section sizes the filter sock accordingly. When sizing the filter sock is complete, the filter sock is wrapped in a plastic cover so that the filter sock can be conveniently transported and installed.

Methods for encasing bodies including smokeless tobacco or a tobacco substitute with a polymeric casing can include coating a compressed body with microfibers, applying tubular casings to compressed bodies, printing netting and webs on compressed bodies, injection molding around compressed bodies, applying a webbing to compressed bodies, placing compressed bodies into a skin forming bath, and including thermoplastic polymers in a compressed body.
