Abstract: A case for holding an article includes a base, a lid having a first side and a second side opposite the first side, such that the lid is connected to the base at the first side and the lid and base together define an enclosed environment when the case is closed. A monitoring device is included that has an accelerometer, a humidity sensor, and a temperature sensor. The monitoring device is attached to the lid such that the monitoring device is in communication with the enclosed environment when the case is closed. The device can be used to detecting tampering with the case and can be installed permanently in the case.

Abstract: A method for preparing a foam-layered packaging material, which method includes the steps of providing an outer shell having a bottom wall and upwardly extending side walls defining an interior space and having an open top; pouring onto the bottom wall of the outer shell a predetermined quantity of a mixture of polyurethane foam-forming reactants; covering the open top of the outer shell with an inner protecting and cushioning layer so as to define a confined space within outer shell; and allowing the mixture of polyurethane foam-forming reactants to foam and completely fill the confined space with polyurethane foam while at the same time forming a direct bond between the foam and the inner cushioning layer over substantially the entire surface of the inner cushioning layer facing the confined space; wherein the predetermined quantity of the polyurethane foam-forming reactants is an amount effective to substantially completely fill the confined space with polyurethane foam and bond the foam with substantially
