Abstract
A method of packaging a fresh meat product on a support member (6) lidded with a twin lidding film (3) including an inner oxygen permeable film (15) and an outer gas impermeable film (16), by providing the twin lidding film (3) as a composite wound up on a single supply roll and, following unwinding and before entering into a lidding station (4), briefly separating the two films (15) and (16) before superposing them again one over the other before the sealing step.
Claims7
A process for the manufacture of a fresh meat package by placing the meat product (14) on a support member (6) and closing the package in a lidding station (4) under a high oxygen-content atmosphere by means of a twin lidding film (3), comprising an inner, food-contact, oxygen-permeable film (15) and an outer oxygen-impermeable film (16), positioned over the meat product and heat-sealed to the periphery of the support member 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, said process comprising the steps of:
- a. providing the twin lidding film (3) as a composite from a single supply roll (1), unwinding the film (3) therefrom, and directing the film into the lidding station (4);
- and
- b. following unwinding and before entering into the lidding station (4), completely separating the oxygen-permeable film (15) and the outer oxygen-impermeable film (16) of the twin lidding film (3), then superposing the two films again before heat-sealing the films to the support member.
