Claims
- 1. A thermoformable, unoriented, dry-bond laminated material having moisture vapor barrier characteristics and a crystallinity level suitable for use in a blister package for pharmaceuticals comprised of:a poly chloro-tri-fluoro ethylene core layer; a first polymer film attached to a first side of said core layer; and a second polymer film attached to the opposing side of said core layer, wherein the laminated material has a crystallinity level of 35% or less.
- 2. The laminated material of claim 1 wherein said first polymer film and said second polymer film are both attached to said core layer by means of an adhesive physically and chemically compatible with said core layer.
- 3. The laminated material of claim 2 wherein said first polymer film and said second polymer film are each PVC.
- 4. The laminated material of claim 2 wherein said first polymer film and said second polymer film have different chemical compositions.
- 5. The laminated material of claim 2 wherein said first polymer film may be any one selected from the group consisting of PVC, PETG, a rubber modified nitrite polymer, polypropylene or polystyrene.
- 6. The laminated material of claim 5 wherein said second polymer film may be any one selected from the group consisting of PVC, PETG, a rubber modified nitrile polymer, polypropylene or polystyrene.
- 7. The laminated material of claim 1 wherein said core layer has a thickness of at least 0.6 mils but not more than 3.0 mils.
- 8. The laminated material of claim 1 wherein said first polymer film and said second polymer film each have a thickness of at least 5.0 mils but not more than 15 mils.
- 9. The laminated material of claim 1 wherein the material has a total thickness of at least 10.6 mils but not more than 33 mils.
- 10. A thermoformable, unoriented, dry-bond laminated material having moisture vapor barrier characteristics and a crystallinity level suitable for use in a blister package for pharmaceuticals comprised of:a poly chloro-tri-fluoro ethylene core layer having a thickness of at least 0.6 mils but not more than 3.0 mils; a first polyvinyl chloride film having a thickness of at least 5.0 mils but not more than 15 mils adhesively attached by means of a heat-activated dry bond laminating adhesive to a first side of said core layer; and a second polyvinyl chloride film having a thickness of at least 5.0 mils but not more than 15 mils. adhesively attached by means of a heat-activated dry bond laminating adhesive to a second side of said core layer, wherein the laminated material has a crystallinity level of 35% or less.
