Abstract:
The coating of a RF active material on a non-RF active substrate material of typical thickness for packaging purposes, can generate sufficient thermal energy to effect strong bonding of the substrate materials. The RF active material may be-deposited on less than the entire inner surface area of the substrate material, preferably, at or near the portion of the substrate surface which represents the heat seal interface. In this manner of application, additional coating or printing of other substances on the substrate surface can be achieved without hampering the heat sealing process. Flexible medical containers capable of containing a product which is maintained and removed under sterile conditions, can be constructed on commercial production machines from these coated non-RF active substrate materials.
