Abstract (en)
[origin: DE10111232A1] The tray is made from a prefabricated blank which forms the base, sidewalls and an edge flange and is covered on the inner face in a composite plastic lining. Grooves(53) impressed at each folding edge face towards the folding direction and are formed on the side subjected to tension during folding. A foodstuffs package comprises the tray filled with contents and covered with a gas tight film passing over the edge and sealed. Independent claims are made for: a) a process for manufacturing the tray in which grooves(53) are impressed in the flat multi-layer card blank and the tray is assembled by folding the sections along the grooves(53) and bonding together. Complete nested trays are then transported to a forming station at which a composite plastic film is applied to the inner surface; b) a cut blank with smooth and rough faces for forming a tray and including grooved folding edges between the base and side sections and also between the side sections and triangular connecting flaps; c) a cut blank for forming a collar for insertion into the tray having a ring-shaped central opening with grooved folding edges for adjacent flap sections and a rectangular outer shape with trimmed corners. Preferred Features: Grooves are formed only along folding edges at which the adjacent sections are folded through high angles.
