Abstract

A twist-tie system, whereby a gang of edge-connected but separable twist ties are fastened to a desired surface. The twist-tie system includes a gang of twist ties, an adhesive layer applied to a portion of one surface of the gang of twist ties, and a removable protective material applied to an exposed surface of the adhesive layer. The protective material can be removed to expose the surface of the adhesive layer to permit fastening of the gang of twist ties to a surface by use of the adhesive layer. At least a portion of the gang of twist ties, spaced from the portion of the one surface of the gang of twist ties, can be formed in a waved profile. Undulations of the waves in this profile extend in a same direction as a longitudinal extent of ties in the gang of twist ties. The removable protective material does not extend beyond a perimeter of the gang of twist ties.
