A method of forming a container () includes heating two webs of material and indexing the webs into a vacuum thermoformer () which forms first () and second trays () simultaneously, wherein the second tray is disposed within a space of the first tray to define a reservoir () therebetween. A portion of the first tray is brought into contact with a flange portion of the second tray, and joined by a heat seal within the vacuum thermoformer. A punch device within the vacuum thermoformer perforates a drain aperture () in a central region of the bottom of the second tray, such that the drain aperture is in fluid communication with the reservoir. The cut-out section is adhered to the bottom of the first tray to eliminate the presence of any scrap material. The joined first and second tray is indexed out of the vacuum thermoformer and trimmed to separate an assembled container from the web supply.

Packaging and processes for facilitating fast, efficient, and reliable production line packaging of products, and more particularly perishable products including meat products. Product trays according to the present invention are formed of non-foam plastic material with three dimensional structure and configuration that imparts an esthetically pleasing appearance and feel to the customer at the point of sale, as well as offering to the consumer a container that is microwavable, dishwasher safe and freezer safe in addition, if desired, to being recyclable. Such packaging and processes are particularly useful in newly emerging automated supply chains where inventory sales are tracked to support centralized processing of meat and other perishable products at centralized facilities for shipment to geographically distant points of sale. In these situations, the packaging must present the requisite esthetic, convenience and performance qualities to the customer at the point of sale even after having been loaded into a shipment container, transported often by truck over hundreds of miles, unpacked and placed in the product display case. Non-foam containers according to the present invention can accomplish these results by featuring separation structure to permit manufacture, storage, stacking, shipment, and dispensing on processing lines with minimum chance or potential of the sort of locking together which can otherwise occur with non-foam containers.
