A plug-in module for the insertion into and extraction from a module frame that has at least one frontal structural bar, including a circuit board, a switch for the active-passive switching of the plug-in module and a swivel-mounted leverpull handle with a gripper arm located in the frontal area of the plug-in module. The core preferably comprises a diene polymer that has low cross-link density or not cross-linked with a reactive co-agent. The films can be metallized, or combined with barrier coatings or layers, for improved gas barrier properties particularly for moisture vapor transmission barrier desired in packaging applications.
