  • Patent number: 5106383
    Abstract: A disposable article, such as a disposable diaper, is provided. The article has a fastening means comprising a film substrate having a target strip and a fastening tape. The target strip comprises a backing film having a first pressure-sensitive adhesive on one face thereof adhered to the film substrate and on the other face thereof a hydrophobic polyvinyl carbamate release coating. The fastening tape has a second pressure-sensitive adhesive on one face thereof for adhesion to the target strip. The target strip release coating has been subjected to ionizing plasma treatment such that the fastening tape has an increase in adhesion to the target strip of at least about 50% over an untreated target strip and which increased adhesion does not decrease more than 60% after storage at about 50.degree. C. for 15 days.

  • Patent number: 5026446
    Abstract: In the continuous manufacture of disposable diapers wherein target strips applied to the diaper are cut from a pressure-sensitive adhesive tape that has a low-adhesion backsize coating, better adhesion of adhesive closure tabs to the target strips is obtained after physically abrading the low-adhesion backsize coating. A preferred abrading medium is a low density open nonwoven fibrous abrasive web.
