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 aims to provide automatic packaging film and a method for preparing the same. Mutually parallel adhesive areas (2) are arranged at intervals laterally on the same side of the film substrate, a non-adhesive area (1) is formed between two adhesive areas (2), and each non-adhesive area (1) and an adjacent adhesive area (2) form a packaging section; between the adjacent packaging sections, the non-adhesive area (1) of a packaging section and the adhesive area (2) of a next packaging section are connected through a separable splicing tape; all the packaging sections are connected through separable splicing tapes to form an entire continuous automatic packaging film (3). The invention solves the technical problems that the film is stuck or broken during automatic packaging, leading to machine shutdown and thus failure of automatic packaging.
