Abstract (en)
[origin: WO2022107181A2] The invention relates to the packaging sector of food products for human consumption. More specifically, the invention relates to a production process for a food tray which is particularly (but not exclusively) suitable for use in controlled atmosphere packaging, and to the tray thus obtained. Said production process for a cardboard food tray (1) comprises the phases of: - providing a sheet (2) of cardboard, where said cardboard is corrugated; - applying a thermo-adhesive substance to areas of said sheet; - die-cutting and creating creases (3) on said sheet (2); - folding said die-cut sheet (4) along said creases (3) and overlapping flaps of previously adhesivised cardboard and applying a source of heat to reactivate said thermo-adhesive substance, to form a shaped tray (1), comprising a bottom (5), side walls (6) and a perimeter edge flange (7), adapted to define a compartment (8) for containing food; - positioning said tray (1) in succession with other trays (1) already shaped to create a stack (9) of stored trays. Said process also comprises the mechanical pressing of at least said perimeter edge flange (7), so as to crush said corrugated cardboard and flatten said perimeter edge flange (7), making its surface flat even at the flaps of overlapping cardboard.
