Abstract
The invention relates to a tray for packaging portions of meat or similar foods that are stored and presented in refrigerated conditions. Said tray is deep-drawn from polystyrene or a similar foam material, and has a base and a peripheral side wall. Said base and said side wall have a liquid-impermeable skin on the inside and the outside. This skin has recesses on the inside of the base and the foam layer that is located between the inner and outer skin is at least partially open-celled and has the effect of absorbing liquid. At least one channel is molded in the inside of the base, said channel essentially completely surrounding a section of the surface of the base and having flanks and a channel floor which also have a liquid-impermeable skin. The flank which is oriented towards said section of the surface has at least one recess which allows the passage of liquid.
