Claims
- 1. A method for producing a composite package for containing articles, wherein said method is comprised of the steps of:
- forming a sheet of polymeric material into a web of a plurality of polymeric trays;
- coating a first side of a paperboard cover means with a coating of a low temperature, heat sealable coating;
- placing said coated paperboard cover means substantially over one of said plurality of polymeric trays with said coating located adjacent to said one of said trays;
- securing said one of said plurality of polymeric trays to said coated paperboard cover means at an initiation temperature of less than 200.degree. F. to form an intermediate composite package;
- trimming said intermediate composite package to form a final matched-edge composite package;
- inserting an article substantially within said final composite package; and
- retaining said article substantially within said final composite package.
- 2. The method, as in claim 1, wherein said forming step is further comprised of the step of:
- thermoforming said sheet of polymeric material.
- 3. The method, as in claim 1, wherein said polymeric material is further comprised of:
- polystyrene.
- 4. The method, as in claim 1, wherein said heat sealable coating is further comprised of:
- a coextrusion of polyethylene and an ethylene-methyl acrylate copolymer.
- 5. The method, as in claim 1, wherein said method is further comprised of the step of:
- coating a second side of said paperboard cover means with a layer of particulate minerals.
- 6. The method, as in claim 5, wherein said particulate minerals are further comprised of:
- clay.
- 7. The method, as in claim 1, wherein said securing step is further comprised of the step of:
- heat sealing said paperboard covers to said one of said polymeric trays.
- 8. The method, as in claim 1, wherein said retaining step is further comprised of the step of:
- folding said final composite package.
- 9. The method, as in claim 1, wherein said method is further comprised of the step of:
- securing a lid means having first and second sides substantially over one of said plurality of polymeric trays.
- 10. The method, as in claim 9, wherein said lid means is further comprised of:
- a low temperature, heat sealable coating located exterior to said first side of said lid means and substantially facing one of said plurality polymeric trays.
- 11. The method, as claim 9, wherein said lid means is further comprised of:
- a coating of particulate minerals located exterior to said second side of said lid means.
