Abstract: The invention provides a flexible plastic formulation capable of being RF sealed, extruded, cast or blow-molded, gas, steam and radiation sterilized. The plastic formulation of the invention comprises: a) from about 40 to about 90 percent by weight of a polyolefin polypropylene based material; b) from about 3 to about 25 percent by weight of a functionialized block copolymer, the functionalized block copolymer consisting essentially of a central block copolymer molecule including generally equal proportions of ethylene and butylene units, and terminal blocks of polystyrene; and c) from about 3 to about 20 percent by weight a nylon. The plastic formulations of the invention are useful in the manufacture of blood bags, tubing and the like.

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.

Abstract: An apparatus for sealing and severing a web of film is provided. The apparatus includes a sealing bar having a body portion including first and second sidewalls and a top portion for melting and severing a portion of a web of film. A backup member is provided located on an opposite side of the film from the sealing bar for urging the film against a portion of the sealing bar. The apparatus also includes a holder for holding the sealing bar, the holder includes a first side and a second side that define a center region for receiving at least a portion of the body of the sealing bar, and first and second sides having shoulders. The shoulders and top portion of the sealing bar are so constructed and arranged that they deflect a bead generated at a molten area of the film when the film is sealed and severed and substantially limit the creation of a resultant bead in a final cooled product.
