The invention relates to a cover or case for goods, in particular for use as a cover or case for hobby or sports equipment. In an embodiment, the case has an inner portion, formed of expanded polypropylene (ePP) and defining a cavity for receiving at least part of the item. The case also includes an outer layer, formed of self-reinforcing polypropylene (srPP), arranged to cover an outer surface of at least part of the inner portion. In further embodiments, the cover is formed of two or more sections that may be arranged to at least partially overlap, wherein adjusting the overlap of the at least two sections changes the dimensions of an inner cavity within the cover or case. The case may be telescoping, in order to provide adjustable dimensions for a cavity within the case.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.
