Abstract: The invention relates to a packaging tray composed of plastic with a base (10) and sidewalls (11) which adjoin the base (10) and delimit a receiving space for a product being packaged, and with a baseplate (2) which is placed onto the upper side of the base (10) and forms a supporting surface for the product being packaged, wherein the baseplate (2) and the base (10) are formed with at least one releasable connecting means for releasably fixing the baseplate (2) to the base (10) of the packaging tray (1), wherein the connecting means are complementary with respect to one another and are formed integrally in the base (10) and in the baseplate (2).

Abstract: The invention relates to a packaging tray (1), produced from a thermoformed plastics sheet, with a base (10), sidewalls (11, 12) and a sealing edge (13) which is formed peripherally on the upper side of the sidewalls (11, 12) and onto which a sealing film (2) can be placed and can be bonded to the sealing edge (13), in which the sealing edge (13) is formed with a contact surface, which is provided for supporting the sealing film, with a profiling in the form of projections (133) in each case forming part of the contact surface and with depressions (134) which run between adjacent projections (133) and interrupt the contact surface, wherein the depressions (134) in each case define a receiving volume.

Abstract: A process and an apparatus for producing a spun-fiber web from filaments of a synthetic polymer which includes a device for taking off the filaments and a web-depositing device with suction unit wherein the filaments are taken off mechanically by means of a take-off roll with a unit for the defined raising of the frictional force between the roll surface and the filaments, the filaments being exposed, in particular, to a vacuum and/or to pressurized air.
