Abstract
A closure strip, for use with a corrugated material, includes an elongated flat thermoplastic sheet member and a plurality of thermoplastic undulations. The elongated flat thermoplastic sheet member has a bottom surface and an opposite top surface. The elongated flat thermoplastic sheet member defines a plurality of linearly disposed and spaced apart openings therethrough. A plurality of thermoplastic undulations is complimentary in shape to the corrugated material. Each undulation extends upwardly from the flat thermoplastic sheet member and defines a void that opens to a different one of the openings defined by the flat thermoplastic sheet member.

A closure strip for use with a corrugated material, comprising:
- a. an elongated flat thermoplastic sheet member, having a bottom surface and an opposite top surface, that defines a plurality of linearly disposed and spaced apart openings therethrough;
- and
- b. a plurality of thermoplastic undulations that are thermoformed into the flat thermoplastic sheet member and that are complimentary in shape to the corrugated material, the plurality of thermoplastic undulations being integral with the flat thermoplastic sheet member and each undulation being continuously covered by thermoplastic, each undulation extending upwardly from the flat thermoplastic sheet member and defining a void that opens to a different one of the openings defined by the flat thermoplastic sheet member so that each undulation opens only along the bottom surface of the flat thermoplastic sheet member underneath the undulation.
