A noise dampening film is provided, and in particular, a film having at least one quiet layer that comprises a polymer resin and from about 5 to 50 weight percent of a styrene-vinyl polyisoprene-styrene block-co-polyisopyrene block triblock polymer. The quiet layer has a tan delta of at least about 0.27 or greater at a temperature range between about 17° C and 40° C. A noise dampening film is provided, and in particular, a film having at least one quiet layer that comprises a polymer resin and from about 5 to 50 weight percent of a styrene-vinyl polyisoprene-styrene block-co-polyisopyrene block triblock polymer. The quiet layer has a tan delta of at least about 0.27 or greater at a temperature range between about 17° C and 40° C. An RF sealable composition and film is provided in which the composition and film includes a blend of an ethylene/alpha-olefin and an ethylene acrylate copolymer. The composition and resulting film has a dielectric loss factor of at least 0.02 and is capable of being radio frequency sealed. Films in accordance with the invention provide RF seals having peel strengths on the order of 500 g/in or greater. In a further aspect, a film is provided having at least one exterior layers that comprises a blend of an ethylene/alpha- olefin copolymer and an ethylene acrylate copolymer. Suitable ethylene acrylate copolymers for use in the invention include of ethylene vinyl acetate (EVA), ethylene butyl acrylate (EBA), and ethylene methyl acrylate (EMA).Se proporciona una película amortiguadora de ruidos, y en particular, una película que tiene al menos una capa silenciosa que comprende una resina polimérica y de aproximadamente 5 a 50 por ciento en peso de un polímero tribloque de bloque de estireno-poliisopreno de viniloestireno-bloque de co-poliisopireno. La capa silenciosa tiene una tan delta de al menos aproximadamente 0.27 ó mayor en un rango de temperatura entre aproximadamente 17°C y 40°C.
