  • Publication number: 20030113519
    Abstract: The present invention provides a waterbase self seal adhesive system utilizing a self seal adhesive containing no natural rubber. The self seal adhesive system is comprised of a transfer (front) adhesive disposed on a transfer (front) web and an anchor (back) adhesive disposed on an anchor (back) web with the two adhesives forming the seal for the package. The self seal adhesives bond to themselves when pressure is applied to close or seal the packaging material. In one embodiment, when peeled apart, the adhesive transfers from one substrate of the package to the other substrate of the package to enable opening of the package and thereafter prevents resealing of the package. In another embodiment, when peeled apart, the adhesive splits, adhesively fails from either or both the front web or the back web, or destroys one or both of the substrates of the package. In either embodiment, primers and release coatings may also be used to enhance performance of the self seal adhesive.

  • Patent number: 4921809
    Abstract: Certain polyethyleneimines are used to coat solid carriers used in immunoassays to improve the sensitivity of the assay over what is obtained without the coating. Use of the invention in enzyme immunoassays yields sensitivities equal to that of radioimmunoassays. A post-coating is also used after the solid carrier has had a layer of capture molecule applied and before the assay is performed, to improve even further the sensitivity, reliability and dynamic range of the assay results.
