A touch fastener product has a base strip of resin carrying both mechanical fastener projections and adhesive, in some cases disposed on raised portions of the base strip. The fastener projections are arranged in discrete fields with lanes between the fields, and the adhesive is disposed within the lanes. The adhesive in each lane is shorter, as measured perpendicularly from the base strip, than the projections nearest the lane, by a distance that is less than ten percent of the width of the lane. In some cases molded stems extend through the adhesive in the lanes. The fastening face of the molded base strip is treated to give the fastening face a higher surface energy than the back face, to resist adhesive delamination during unspooling.
