    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.

    Abstract: A container is provided having first and second side walls. The first side wall comprises first and second layers with the second layer overlapping a portion of the first layer to define an overlap area. A sealing flange extends from the first layer outward of the overlap area and the second side wall is connected to the first side wall along the sealing flange to define an inner chamber therebetween. The second side wall and the sealing flange define a first layered structure comprising a plurality of layers along the sealing flange. The overlap area and the second side wall define a second layered structure that has more layers than the first layered structure. The container is sealed by positioning peripheral edges of the first and second side walls into registration so that the overlap area is centrally disposed over the second side wall. Sealing energy is then applied to the first layered structure to define a peripheral seam.
