In the Top Seal packaging process, the barrier film is positioned on the tray and is heat-sealed around the perimeter edges. The air is removed during the process (vacuum phase) and is replaced by a mixture of preserving gases (filling phase). This is why it is important for both tray and film to possess ultra-high barrier properties.
This technology has the advantage of being extremely reliable since it obtains zero oxygen residues, something that extends the life of the foodstuff to a considerable degree.
