Abstract: A solid thermoformed plastic tray (10) provided with a base (11), a plurality of sidewalls (12, 13, 14, 15) extending upwardly and slightly outwardly from said base (11), a primary flange (20) integrally joined to the upper edges of the sidewalls (12, 13, 14, 15) and extending outwardly all around the upper periphery of the sidewalls (12, 13, 14, 15), a rim (21), i.e., a downward flap extending downwardly and tapering slightly outwardly from the outer periphery of the primary flange (20), and a secondary flange (22), i.e., an overhanging portion extending outwardly from the lower edge of the rim (21), said tray being characterized in that a plurality of strengthening ribs (23) extend substantially vertically along the rim (21) and outwardly with respect to the tray body.

Abstract: A method of manufacturing together a support (10) and frame (20) of a container assembly (1), the method comprising: providing a single mold (100) with a first cavity (110) defining the support (10) and a second cavity (120) defining the frame (20); injecting first material into the first cavity (110); and injecting second material into the second cavity (120); wherein the first and second materials are different materials.

Abstract: The present invention relates to a gas barrier and liquid absorbent container (1) for use in the modified atmosphere packaging of food products which tend to release liquids. The container of the invention comprises a base and upwardly extending side walls terminating in a continuous flange horizontally projecting from the side walls, and comprising an inner part of a liquid pervious material (20), and an outer part of a liquid and gas barrier material (10), said inner and outer parts being joined together at the side walls and being spaced apart from each other at the base to define an interspace (30). A circumferentially extending continuous portion (11) of the surface of the liquid and gas barrier material is exposed to provide an area for a gas barrier closing lid to be sealed. The invention further relates to a method of manufacture of said container, to its use in the packaging of food products under a modified atmosphere and to the gas-tight packages thus obtained.

Abstract: A method of packaging a fresh meat product on a support member (6) lidded with a twin lidding film (3) including an inner oxygen permeable film (15) and an outer gas impermeable film (16), by providing the twin lidding film (3) as a composite wound up on a single supply roll and, following unwinding and before entering into a lidding station (4), briefly separating the two films (15) and (16) before superposing them again one over the other before the sealing step.

Abstract: A form-fill-seal machine has an ultrasonic vibration emitter head 11 positioned outside the tube being formed by the overlapping of the margins 3 and 5 of a film web, and an anvil 13 positioned inside the tube defined by those margins, the anvil being mounted on an anvil carrier 25 which is supported by a frame element entirely independent of the forming box 1 used to fold the film, so as to isolate the anvil from vibrations sustained from the forming box. The anvil carrier can be mounted directly to a carrier body for the ultrasonic vibration emitter, and preferably has the shape of an inverted letter J where the anvil is positioned near the toe 25a of the J, the mounting to the sealing machine frame is at the top of the stem 25c of the J, with a slot 25b between the toe 25a and the stem 25c.
