ABSTRACT:
A pressure-sensitive tape having a closed-cell polymer foam backing strip and a pressure-sensitive adhesive is disclosed. The tape is formed into a roll so that the adhesive of one layer is in direct physical contact with the foam of the next layer, without the use of release paper or release coatings. The tape may be unwound without significantly disrupting either the adhesive layer or the foam layer. The foam is preferably a closed-cell cross-linked polyethylene copolymer and the adhesive is preferably a hypoallergenic acrylic-based adhesive.
