Abstract

A heat insulating layer exists between the attachment layer and the closure profile of a resealable closure mechanism for a package. A heat and pressure sealing process is used to attach the closure profile to a resealable package. A heat-sealing bar is used to apply a heat load into the attachment layer causing the attachment layer to fuse with the film of the package. The beat insulating layer insulates the profile layer from the heat load to prevent distorting or melting of the profile layer. The heat insulating layer also supports the profile members perpendicular to their respective base strips to facilitate opening and closing of the resealable package.
