  • Publication number: 20150232241
    Abstract: A multi-layer control device or one-way valve (100) includes: a first layer (10) having at least one first opening (12) formed therein; and a second layer (20). The first and second layers are joined together such that at least one channel (24) is defined therebetween, which channel selectively permits gas flow from the first opening out of the device/valve. In operation, the valve selectively opens to permit gas flow through the channel in response to a pressure differential on opposing sides of the valve, wherein the pressure differential sufficient to open the valve (?Po) dynamically varies over time. Suitably, a material is arranged in the channel which experiences a change that precipitates the dynamic variation of ?Po.

  • Patent number: 8163384
    Abstract: This invention relates to antimicrobial composites, films, labelstocks and labels. The antimicrobial composites comprise a mixture of (A) a terpolymer prepared from a mixture comprising (i) an olefin, (ii) at least one copolymerizable comonomer comprising ethylenically unsaturated organic acids or esters, vinyl esters of saturated carboxylic acids and mixtures of two or more thereof, and (iii) carbon monoxide, and (B) an antimicrobial composition which comprises at least one metal chlorite and at least one hydrophilic material capable of reacting with the metal chlorite when exposed to water. The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time.

  • Publication number: 20110253232
    Abstract: A multi-layer valve is provided for allowing oxygen to enter a package while maintaining a level of fluid and leak resistance. The multi-layer valve includes a first layer of adhesive that has a top and bottom face with the bottom face being adhered to a release liner. A permeable layer is provided over the first layer of adhesive, a second layer of adhesive that has a top and bottom face. The bottom face of the first adhesive layer is adhered to the permeable layer and the top face of the first adhesive layer is adhered to a cover layer such that the bottom face of the second layer of adhesive is separable from the permeable layer while the top face of the second layer of adhesive maintains adhesion with the cover layer.

  • Publication number: 20040142495
    Abstract: An article for detecting the presence, or the absence, of an analyte. The analyte is indicative of a change in the status of a packaged material. The article generally includes a facestock film having first and second surfaces, an adhesive layer adjacent to the facestock film, and a detecting system adjacent to the facestock film. A measurable analyte can be in vapor and/or liquid form, and the detecting system indicates whether the analyte is present. That is, the detecting system responds to contact with the analyte by indicating that such contact has occurred, or that the analyte is present.

  • Patent number: 5629087
    Abstract: A method of adhesively securing first and second members together by sliding movement of the members along an interface where the members are to be joined by an adhesive layer having opposed normally tacky and normally sliding-movement-resistant sides includes the step of applying a liquid to an exposed side of the adhesive side to reduce its tackiness. After sliding assembly of the members, the liquid is transmitted from the side of the adhesive to the interior of the adhesive to enable tack increase at the exposed adhesive side and adhering of the members together. The adhesive includes a moisture absorbing component to enable liquid accumulation at the exposed side and subsequent transmission to the adhesive interior.
