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.

Abstract: The present invention provides a method for connecting rounded members between planar members comprising the steps of providing a rounded member having an outer layer having a first melting temperature range and an inner layer concentrically disposed within the outer layer and having a second melting temperature range, the second melting temperature range being warmer than the first melting temperature range, providing a pair of opposed planar members, the planar members each having a melting temperature within the first melting temperature range, positioning an end portion of the rounded member between perimeter edges of the pair of planar members to define an interface area, applying pressure to the interface area to collapse the end portion of the rounded member to essentially a flattened position, applying sealing energy to the interface area to heat the rounded member to a temperature within the first melting temperature range but below the second melting temperature range, thereby forming a weld between the planar members, and the rounded member in the interface area, and, releasing the pressure to the interface area wherein the end portion of the rounded member returns to an open position.

Abstract: A multiple layer structure comprising a skin layer, a barrier layer, a radio frequency susceptible layer having a first polyolefin in an amount within a range of 30-60% by weight, a second polyolefin in an amount within the range of 25-50% by weight, a radio frequency susceptible polymer in an amount within the range of 3-40% by weight, a styrene and hydrocarbon block copolymer in an amount within the range of 5-40% by weight of the sealant layer.
