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.

The invention relates to a food packaging unit (20) comprising a food container (1) for receiving a liquid, pasty or free-flowing food. The injection-moulded, single-component, cup-shaped base body (2) of the food container surrounds, with a wall (5), a bottom (6) and an outwardly projecting collar (7), an opening (4) which is closed by a food-container-covering film (10) applied to the collar (7). The food container (1) is injection-moulded in a single layer from a polymer blend comprising two components, a first component of which being PVOH or a PVOH copolymer. The food-container-covering film (10), which can be applied to the plastic food container (1) in order to close the opening (4) by sealing, welding or adhesion, comprises a cellulose-containing layer which is coated with PVOH, or a PVOH polymer blend layer.

A method of producing a substrate includes: applying a composition on a metal basal plate to form a coating film; and forming a metal-containing layer on at least a part of the coating film. The composition contains a solvent, and a polymer having a first terminal structure and a second terminal structure in a single molecule. Each of the first terminal structure and the second terminal structure is at least one selected from the group consisting of a structure represented by formula (1) and a structure represented by formula (2). A.sup.1 and A.sup.2 each independently represent a monovalent group having a functional group capable of forming a chemical bond with a metal atom. L.sup.2 represents —S—, —NR—, or —NA.sup.22-, wherein A.sup.22 represents a monovalent group having a functional group capable of forming a chemical bond with a metal atom. ##STR00001##

One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.

The invention relates to a laminate (10; 10a) having a core (12) containing a thermoplastic polymer and having metal cover layers (16) disposed on either side of the core (12), each cover layer (16) being connected to the core (12) via an adhesive layer (14) having at least one polymer layer (15).
