Abstract
Abstract A laminated-sheet-packaging material having good moisture-vaporbarrier properties and providing reduced risk of deleterious effects from buildup of static electricity if formed from an aluminum film having a layer of protective material on one face and a layer of heat-sealable, electrically conductive plastic material on the other face, the electrically conductive plastic material forming the inner surface of the package.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
A composite laminated packaging material for sealably packaging items which could be damaged by static electricity, said packaging material being in sheet form and comprising a continuous protective layer of thin sheet metal foil, a layer of sheet material secured to one face of said metal foil, which face would constitute the outer layer of a package, and a continuous layer of heat-sealable synthetic organic polymeric plastic material made electrically conductive by addition thereto of a nonmetallic filler adhered to said metal layer on its opposite face, a portion of said synthetic organic polymeric plastic material being adapted to be exposed when the packaging material is formed into a package for convenient attachment to a grounding connection.
Claim 2
Dependent Claim
117 words
A composite laminated packaging material for sealably packaging items which could be damaged by static electricity, said packaging material being in sheet form and comprising a continuous protective layer of thin sheet metal foil, a layer of sheet material secured to one face of said metal foil, which face would constitute the outer layer of a package, and a continuous layer of heat-sealable synthetic organic polymeric plastic material made electrically conductive by addition thereto of a nonmetallic filler adhered to said metal layer on its opposite face, a portion of said synthetic organic polymeric plastic material being adapted to be exposed when the packaging material is formed into a package for convenient attachment to a grounding connection.
Claim 3
Dependent Claim
37 words
A composite laminated packaging material as set forth in claim 1 wherein said layer of sheet material which is secured to said one face of said metal layer is also electrically conductive synthetic organic polymeric plastic material.
Claim 4
Dependent Claim
17 words
A composite laminated packaging material as set forth in claim 1 wherein said nonmetallic filler is carbon.
Claim 5
Dependent Claim
125 words
Plural sheet portions of a composite laminated material heat sealed and formed into a container for itEms which could be damaged by static electricity, said laminated material comprising a continuous protective layer of thin sheet metal foil, a layer of sheet material secured to the outer face of said metal foil, and a continuous layer of synthetic organic polymeric plastic material, made electrically conductive by the addition thereto of a nonmetallic filler, adhered to the inner face of said metal foil, the layers of plastic material of said sheet portions being disposed to define the inside surfaces of said container and being bonded together, and a portion of said synthetic organic polymeric plastic material extending beyond said container for convenient attachment to a grounding connection.
Claim 6
Dependent Claim
125 words
Plural sheet portions of a composite laminated material heat sealed and formed into a container for itEms which could be damaged by static electricity, said laminated material comprising a continuous protective layer of thin sheet metal foil, a layer of sheet material secured to the outer face of said metal foil, and a continuous layer of synthetic organic polymeric plastic material, made electrically conductive by the addition thereto of a nonmetallic filler, adhered to the inner face of said metal foil, the layers of plastic material of said sheet portions being disposed to define the inside surfaces of said container and being bonded together, and a portion of said synthetic organic polymeric plastic material extending beyond said container for convenient attachment to a grounding connection.
Claim 7
Dependent Claim
28 words
A container as set forth in claim 4 wherein said sheet material forming said outer face of said container is also electrically conductive synthetic organic polymeric plastic material.
Claim 8
Dependent Claim
14 words
A container as set forth in claim 4 wherein said nonmetallic filler is carbon.
Claim 9
Dependent Claim
124 words
Plural sheet portions of a composite laminated material heat sealed and formed into a container for items which could be damaged by static electricity, said laminated material comprising a continuous protective layer of thin sheet metal foil, a layer of sheet material secured to the outer face of said metal foil, and a continuous layer of synthetic organic polymeric plastic material, made electrically conductive by addition thereto of a nonmetallic filler, adhered to the inner face of said metal foil, the layers of plastic material of said sheet portions, being disposed to define the inside surfaces of said container and being bonded together and means electrically connected to said plastic material and extending outwardly from said container for convenient attachment to a grounding connection.
Claim 10
Dependent Claim
124 words
Plural sheet portions of a composite laminated material heat sealed and formed into a container for items which could be damaged by static electricity, said laminated material comprising a continuous protective layer of thin sheet metal foil, a layer of sheet material secured to the outer face of said metal foil, and a continuous layer of synthetic organic polymeric plastic material, made electrically conductive by addition thereto of a nonmetallic filler, adhered to the inner face of said metal foil, the layers of plastic material of said sheet portions, being disposed to define the inside surfaces of said container and being bonded together and means electrically connected to said plastic material and extending outwardly from said container for convenient attachment to a grounding connection.
Claim 11
Dependent Claim
