The indicator tapes are useful to maintain a sterilization wrapper containing articles to be sterilized in a closed position during sterilization, and normal pre- and post-sterilization handling, while also providing a means to indicate if the wrapped articles have passed through a sterilization cycle. After use, the sterilization indicator strip is easily removed, and the adhesives coating the sterilization indicators, and preferably also the backing strips, disperse an aqueous alkali solution, such as are found in commercial laundries.

  • Patent number: 5601890
    Abstract: The present invention provides an acrylated polyolefin tubing (12) crosslinked by irradiation. The tubing (12) is electrically insulating and can be heat shrunk upon a substrate (14) for perfecting a fluid tight seal therewith. The tubing (12) remains adhesively sealed to the substrate (14) and maintains heat sealability after cyclic autoclave sterilization. Moreover, the subject tubing does not permanently discolor after cyclic gamma or electron beam sterilization. The tubing (12) is particularly useful as an outer sheath for electro-surgical instruments (18).

  • Patent number: 5593771
    Abstract: A barrier laminate for attachment to the outer surface of a structure, such as a house prior to attachment of its siding, to cover joints between structural members assembled to form the structure. The barrier laminate comprises a flexible elongate barrier layer having minute passageways between its major surfaces affording passage of water vapor while restricting the passage of liquid water and air between its major surfaces. A portable carrier having a pair of hubs engaging a roll of the barrier laminate and having a pair of trailing rollers which may be used to adhere exposed layers of pressure sensitive adhesive along each of the opposite edges of the barrier layer to structural members on opposite sides of a joint therebetween.

  • Patent number: 5580630
    Abstract: A multi-layer article that includes a layer of a water-soluble polymer that provides a water-removable, non-tacky film over an adhesive layer and/or acts as an adhesive for securing the multi-layer article to a substrate, such as concrete, when wetted. The article forms a water barrier capable of being secured to an area of potential water flow including a layer of flexible, water-impermeable sheet material having a continuous or discontinuous coating of a water-soluble polymer thereon. When the water-soluble polymer is wetted to at least partially solubilize the water-soluble coating, the polymer readily adheres the article to a substrate at the area of potential water flow.
