The presently disclosed subject matter relates to packaging for products (such as fresh red meat) that are enclosed between a support member and a lid (i.e., a film). More specifically, the presently disclosed subject matter relates to packaging comprising an elevation unit that raises the profile of the packaged product to contact the lid at any desired time, such as at the time of retail display.

1. A package for housing an oxygen-sensitive or pressure-sensitive product, said package comprising: a. a support member comprising continuously connected side walls and a base for supporting said product said side walls extending perpendicular to said base and having an outwardly extending flange at an edge distal to said base,b. an elevation unit comprising a separate sealed package, said elevation unit attached to an interior surface of said support member and in an initially non-elevated state; said oxygen-sensitive or pressure-sensitive product resting on said elevation unit; andc. a lidding film; wherein after on demand initiation said elevation unit is elevated and said product contacts said film. 2. The package of claim 1, wherein said product is red meat. 3. The package of claim 1, wherein said elevation unit comprises a mass of compressed resilient material contained in a pouch and held in compressed condition under vacuum, said mass of material being adapted upon exposure to atmospheric pressure to expand to an uncompressed state. 4. The package of claim 3, wherein said mass of resilient material is exposed to atmospheric pressure upon puncturing of said pouch. 5. The package of claim 1, wherein said elevation unit comprises a pouch comprising a valve, said pouch being adapted to hold a fluid. 6. The package of claim 1, wherein said elevation unit comprises a multi-compartment pouch that houses two or more components that can be mixed on demand to produce a gas. 7. The package of claim 1, wherein said package is a modified atmosphere package. 8. The package of claim 1, further comprising an oxygen-sensitive or pressure-sensitive product resting on said elevation unit. 9. A method of inducing bloom of an oxygen-sensitive or pressure-sensitive product on demand, said method comprising: a. providing a package comprising: i. a support member comprising continuously connected side walls and a base for supporting said product said side walls extending perpendicular to said base and having an outwardly extending flange at an edge distal to said base,ii. an elevation unit comprising a separate sealed package, said elevation unit attached to an interior surface of said support member and in an initially; andiii. a lidding film;b. placing said product on said elevation unit in said support member;c. bonding said film to said outwardly extending flange of said support member; andd. initiating said elevation unit to provide product-to-film contact on demand. 10. The method of claim 9, wherein said oxygen-sensitive product is red meat. 11. The method of claim 9 wherein said elevation unit comprises a mass of compressed resilient material contained in a pouch and held in compressed condition under vacuum, said mass of material being adapted upon exposure to atmospheric pressure to expand to an uncompressed state. 12. The method of claim 11, wherein said mass of resilient material is exposed to atmospheric pressure upon puncturing of said pouch. 13. The method of claim 9, wherein said elevation unit comprises a pouch comprising a valve, said pouch being adapted to hold a fluid. 14. The method of claim 9, wherein said elevation unit comprises a multi-compartment pouch that houses two or more components that can be mixed on demand to produce a gas. 15. The method of claim 9, wherein said package is a modified atmosphere package. 16. A method of inducing product-to-film contact in a package, said method comprising: a. providing a package comprising: i. a support member comprising continuously connected side walls and a base for supporting said product,ii. an elevation unit; andiii. a lidding film;b. placing an oxygen-sensitive or pressure-sensitive product on said base of said support member;c. bonding said film to said support member; andd. initiating said elevation unit to provide product-to-film contact on demand. 17. The method of claim 16, wherein said oxygen-sensitive product is red meat. 18. The method of claim 16, wherein said elevation unit comprises a mass of compressed resilient material contained in a pouch and held in compressed condition under vacuum, said mass of material being adapted upon exposure to atmospheric pressure to expand to an uncompressed state. 19. The method of claim 18, wherein said mass of resilient material is exposed to atmospheric pressure upon puncturing of said pouch. 20. The method of claim 16, wherein said elevation unit comprises a pouch comprising a valve, said pouch being adapted to hold a fluid. 21. The method of claim 16, wherein said elevation unit comprises a multi-compartment pouch that houses two or more components that can be mixed on demand to produce a gas. 22. The method of claim 16, wherein said package is a modified atmosphere package.
