摘要： Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The new films are compatible with known coextrusion manufacturing techniques, and can also be made without the use of adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined in such a way that delamination of the film is likely to occur along a plurality of delamination surfaces corresponding to interfaces between particular pairs of layers for which the peel strength is reduced relative to the peel strength at other layer interfaces within the film. The absence of an adhesive between peelable layer packets results in the delamination being irreversible.

摘要： A thin walled cross-linked polyethylene (PEX) pipe having a reinforcing material disposed around an exterior wall thereof is provided. As the PEX pipe passes through an extrusion die, a thread guide applies a plurality of reinforcing threads in a particular pattern to the exterior surface thereof to allow for uniform three-dimensional (axial and radial) tensile properties so as to achieve optimum reinforcement of the pipe wall while maintaining its flexibility and without significantly increasing the thickness of the wall or the weight of the PEX pipe.

摘要： The present invention provides a system and method for delivering fluid. In one embodiment, the system and method include a container to hold the fluid, and a closed-end tube having a first end in communication with the container and a closed second end. The closed second end is contoured in a pattern to form a zone of weakness. The zone of weakness facilitates reduced force necessary for an access spike to puncture the closed second end.

摘要： A food package comprising a two piece sealed package including metal free container and peelable lid portions which are readily separable from each other. The container is cup shaped and has a top opening and a substantially flat peripheral rim around the opening. The lid comprises a composite film having a shape which conforms to the shape of the opening and is attached to the rim. The film has a first outer polyamide or polyolefin layer attached to an inner layer of either an ethylene vinyl alcohol copolymer or a blend of a polyamide with an ethylene vinyl alcohol copolymer, which is attached to a second outer polyamide or polyolefin layer. The metal free packaged product allows the detection of metal contaminants inadvertently mixed with the food by scanning the product in the container to determine the presence of metal contaminants in the container.
