Abstract
A connection mechanism including a plurality of microstructure features. The connection mechanism includes a first strip, with a plurality of protrusions extending from the first strip, and a second strip, with a plurality of protrusions extending from the second strip. The protrusions define grooves between adjacent protrusions. A pressure sensitive adhesive is provided in at least some of the grooves. When the first and second strips are brought together, the protrusions from one strip are received in the grooves of the other, and some of the protrusions contact the pressure sensitive adhesive, thereby connecting the first and second strips. The connection mechanism can be used as a closure mechanism for a plastic storage bag.
