Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

A sealing device with film sealer for localized heating to bond film material as in one having a high temperature resistance (e.g., ceramic) substrate with a properly sized groove for receiving a heater element as in a flat faced wire band in a tight, flush to adjacent film presentation surface arrangement. A stacked ceramic plate set with a wire band received within a groove defined by a smaller height intermediate stack insert is a suitable substrate. The band is retained flush by a positioner fixer system that securely locks down one end for band tightening and the other end is provided at an access location of said housing body for clamping and tensioning the heater element into ready for use position within the groove. The edge sealer is suited for use as a product-in-bag sealing device (products such as air, foam, foodstuff, etc.) with the heater element placed in contact with film material to form a seal. A drag seal arrangement, where film layers are drawn past a fixed or adjustably mounted heater element to achieve bonding of one plastic film layer to another, is an example. The invention avoids repeated sealer replacement particularly when the film source (e.g., a film roll) has yet to run out.
