A low-melt plastic fastener. According to one embodiment, the low-melt plastic fastener is shaped to include a flexible filament having a first cross-bar at a first end, and a second cross-bar at a second end. The filament, the first cross-bar, and the second cross-bar may be formed from the same material and may be molded as a unitary structure. Preferably, the fastener is molded as part of a length of continuously connected ladder stock. The plastic fastener is preferably made from a formulation consisting of about 60-99%, by weight, of a low-melt polyurethane and 1-40%, by weight, of a styrene acrylonitrile. The formulation is selected so that the filament melts when heated for about 10 minutes at 130-180° C.
