Abstract: The present invention provides a flowable material container assembly having a membrane tube disposed coaxially within a port tube. The membrane tube has an outer layer, a core layer, and an inner layer. The outer layer is a blend of a polyolefin and a thermoplastic elastomer. The core layer is a blend of a polyolefin and a thermoplastic elastomer. The inner layer is a blend of a polyolefin, a radio frequency susceptible polymer, and a thermoplastic elastomer.

Abstract: The present invention provides a multiple layer thermoplastic structure of a (1) skin layer selected from the group consisting of polypropylene, ethylene homopolymers having a density of from about 0.930 g/cc to about 0.960 g/cc, and ethylene homopolymers having a density of from about 0.930 g/cc to about 0.960 g/cc blended with an ethylene and a-olefin copolymers having a density less than about 0.930 g/cc, the skin layer having a thickness of greater than about 3.0 mils; (2) a radio frequency susceptible layer adhered to the skin layer, the radio frequency susceptible layer having a dielectric loss greater than 0.05 at 1-60 MHz and at temperatures of ambient to 250° C., the radio frequency susceptible layer having: (a) a first polyolefin selected from the group consisting of polypropylene and polypropylene copolymers, (b) a second polyolefin selected from the group consisting of ethylene copolymers, ultra-low density polyethylene, polybutene, and butene ethylene copolymers; (c) a radio frequency susceptible polymer selected from the group consisting of (i) ethylene copolymers having 50-85% ethylene content with comonomers selected from a first group consisting of acrylic acid, methacrylic acid, ester derivatives of acrylic acid with alcohols having 1-10 carbons, ester derivatives of methacrylic acid with alcohols having 1-10 carbons, vinyl acetate, and vinyl alcohol (ii) homopolymers and copolymers containing at least one segment of urethanes, esters, ureas, imides, sulfones, and amides, and (d) a compatibilizing agent of a styrene and hydrocarbon copolymer; wherein the structure when fabricated into a 50 ml container has a water vapor transmission rate of less than 8% by weight after the container has been autoclaved at 121° C. for 20 minutes and stored for 90 days in an environmentally regulated compartment having 15% relative humidity at 40° C.
