A process for the manufacture of a fresh meat package, by, optionally, placing the meat product (14) on a support member (6) and closing the package in a packagingstation (4) under a high oxygen-content atmosphere by means of a composite film (3), comprising an inner, food-contact, oxygen-permeable film (15) and an outer oxygen-impermeable film (16), so as to bind a confined volume (19) within the package containing at least an amount of oxygen effective to inhibit discoloration of the packaged meat product. The process comprises the steps of a. providing from at least a supply roll (1) an inner food-contact oxygen-permeable film (15) and an outer oxygen-impermeable film (16); b. unwinding the films (15, 16) and directing the films into the packagingstation (4); c. inspecting with regard to a predetermined range of wavelengths at least one of the films (15,16) by at least one light beam in order to detect whether the outer oxygen-impermeable film (16) is positioned externally tothe inner, food- contact, oxygen-permeable film (15) in the packagingstation (4). |
