Fresh meat packaging
Abstract
Abstract A SYSTEM FOR PACKAGING FRESH MEAT BEFORE THE MEAT REACHES ITS RETAIL OUTLET OR COMMERCIAL USER. THE FRESH MEAT IS INSERTED IN AN OXYGEN PERMEABLE PLASTIC FILM PACK, WHICH PACK IS THEN PLACED INTO A SUBSTANTIALLY OXYGEN IMPERMEABLE OUTER CONTAINER. BOTH THE PACKS AND CONTAINER ARE VACUUMIZED IN A ONE-STEP OERATION, AN APPROPRIATE DEVICE ON THE OUTER CONTAINER PERMITTING SUCH SIMULTANEOUS EVACUATION. PREFERABLY, THE OUTER CONTAINER IS THEN SHRUNK TO FORM A TIGHT PACKAGE. THE COMPLETED PACKAGE IS THEN SHIPPED TO THE RETAIL STORE OR RESTAURANT WHERE THE OUTER CONTAINER IS REMOVED WHEN THE MEAT PRODUCT IS READY TO BE DISPLAYED OR USED. THE OXYGEN PERMEABLE PACKS CAN THE BE POST SHRUNK TO HASTEN OXIDATION OF THE MEAT TO A RED BLOOM AND TO IMPROVE THE APPEARANCE OF THE PACKS.
