Corrugated sticky tape bag tie closure

The method of making a corrugated sticky tape bag tie closure for closing the neck of a bag comprising the steps of applying on at least one side of a tape of plastic material at alternating areas a pressure sensitive adhesive, and folding the tape into corrugations at alternating areas so that the adhesive coated areas engage and are covered by adjacent non-coated areas to prevent exposure of the adhesive while the tape is in the corrugated condition and to permit exposing the adhesive when the tape is pulled lengthwise thereby opening up the corrugations so that when the tape is wrapped around the neck of the bag the adhesive is secured to the bag and to the adjacent surface of the tape to effect a closure of the bag.

A thermoplastic bag having a corrugated sticky tape bag tie closure comprising a thermoplastic bag having two panels forming an open top, closed bottom bag, said panels being joined along the sides of said bag, and a corrugated sticky tape bag tie closure secured at one end to one of the sides of said bag adjacent the open top thereof, said corrugated sticky tape bag tie closure comprising a tape of plastic material coated on at least one side at alternating areas with a pressure sensitive adhesive, the tape being folded into corrugations at alternating areas so that the adhesive coated areas engage and are covered by adjacent non-coated areas to prevent exposure of the adhesive while the tape is in the corrugated condition and to permit exposing the adhesive when the tape is pulled lengthwise thereby opening up the corrugations so that when the tape is wrapped around the neck of the bag the adhesive is secured to the bag and to the adjacent surface of the tape to effect a closure of the bag.
