ABSTRACT:
A reclosable fastener strip for securing to a film web comprises first and second elongated profile strips having interlocking hooks, recesses and protuberances. Each hook, as extruded, has a half arrowhead-shaped tip, a concave or partial-concave tail, and a generally upstanding neck connecting the tip and tail. Each recess has a base with a pair of generally upstanding neck elements disposed on opposite ends of the base. The base does not extend laterally beyond the neck elements. Each protuberance, as extruded, has a rounded tip, a concave or partial-concave tail, and a generally upstanding neck portion connecting the tip and tail. The profile strips are readily secured to the web without entrapping air between the profile strips and the film web and form an vacuum tight seal. The interlocking hooks, recesses and protuberances are sized, constructed and arranged to provide a vacuum tight seal upon interconnection thereof.
