A package includes a patch and a packaging film. The patch comprises a support and a sealing layer comprising chlorite ions. The support is permeable to chlorine dioxide. The packaging film has an inner surface defining at least a portion of an interior space of the package for housing an article. The packaging film is substantially impermeable to chlorine dioxide and is transparent to ultraviolet light. The patch is affixed to the inner surface of the packaging film by the sealing layer. Chlorine dioxide may be generated by subjecting the package to ultraviolet (UV) light such that the UV light reaches the sealing layer of the patch to convert the chlorite ions to chlorine dioxide.

The present invention relates to an adhesive compositions, facestocks and/or packaging labels containing same, where such compositions, facestocks and/or labels are designed to facilitate the recyclability of a plastic article formed from any suitable polymer or mixture of polymers (e.g., a polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), or others of all plastic types), or even glass bottles. In another embodiment, the present invention relates to a method for removing an adhesive composition, facestock and/or packaging label containing same, from a plastic article that is to be recycled.

The pad body (18) has a first body surface (20) and an opposed second body surface (22). The first body surface (20) is configured to be coupled to an outer surface (14) of the device (10). The second body surface (22) is configured to engage the engagement surface (16). The pad body (18) is formed at least in part from a body material (18A) including high-density polyethylene. The second body surface (22) of the pad body (18) has a static coefficient of friction of at least approximately 1.0. The second body surface (22) includes a plurality of spaced apart surface features (234), each of the plurality of surface features (234) having a feature height (358) of between approximately 0.15 millimeters and 1.00 millimeters. The adhesive material (232) is positioned on the first body surface (20) such that the first body surface (20) is configured to be fixedly coupled to the outer surface (14) of the device (10).

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 stress tearable tape includes an elongated film and a hand tearing arrangement. The film has a non-adhesive surface and an opposed adhesive surface, and defines a longitudinal direction and a transverse direction. The hand tearing arrangement includes a plurality of pinholes formed along the longitudinal direction of the film. With the combination application of internal force, shear tension, compression tension, pinhole arrangement, and material's biaxial structure, and users' habit together, each of the pinholes enables the film being torn by hand with a force starting at one of the pinholes, such that the film is hand tearable at any section in the transverse direction thereof.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.

A patch is provided and described that can be used with the installation of a cured-in-place structural liner in a conduit when the conduit has protrusions into the conduit. The patch is made with similar material to the liner, or felt, and is impregnated with epoxy. The patch may be shaped to more closely match the anticipated curve of the outer surface of the liner. Tools for the installation of the patches, a method of use, and tools for measuring the quality of the installation of the patch before the installation of the structural liner, are also described.
