ABSTRACT:
A highly conformable adhesive tape which comprises a highly extensible and elastic backing film laminated with an adhesive layer to form the tape. The adhesive is a normally tacky and pressure-sensitive elastomeric adhesive coated on at least one of the film surfaces. The film possesses a lengthwise elongation to break of at least about 200 percent, and a 50 percent rubber modulus of not above about 2,000 lbs./sq. inch. The tape is easily stretchable and normally may be removed easily from an application surface by stretching the tape lengthwise in a direction substantially parallel to the surface. This characteristic is highly important in medical applications where painless removal is desirable.
