Abstract
A tape is made of plastic with high elongation, then is coated on one or both sides with pressure-sensitive adhesive. The adhesive is then coated with a brittle coating material. In use, the tape is manually stretched, causing the brittle coating to crack and separate, exposing the adhesive. The tape is then wrapped around the neck of a bag to effect a closure.
