Abstract: A vacuum shell (10) defines an inner cavity (18) in which particulate materials are packed via vacuum pressure. In use, the vacuum shell (10) is positioned within the container (such as sack (16)), and the open end 15 of the shell 10 is brought into contact with a surface (such as platform (17 or 17')) such that a vacuum tight compartment is created. Particulate material is supplied through port (26 or 27) into the inner cavity (18) while vacuum pressure is applied. The particulate material is densified within the inner cavity (18) under the vacuum pressure, and when the volume/quantity of particulate is achieved, the vacuum pressure ceases, and the vacuum shell (10) is withdrawn from the container. To enhance filling, the filter media inside the vacuum shell (10) can be periodically pulsed with air or other suitable gases to remove particulate cakes from the filter material (22).

Abstract: A homogeneous dry mechanical blend of freely flowable pellets, granules or powders comprising plastic resin and/or plastic additive concentrates is vacuum packaged in order to lock the constituents of the blend in place and eliminate their segregation due to differences in specific gravity, size and shape. The vacuum packaged composition remains immobilized until the vacuum package is opened and the vacuum is released. Thus, the homogeneity of the blend is maintained during shipping, handling and storage. Providing a homogeneous customized mechanical blend of plastic compounded additive concentrates is an economical and preferred method of providing an intermediate product to a user for the molding or extruding of a plastic end product.

Abstract: There is disclosed a method for the preservation of an article by housing an article such as a food, cereal and pharmaceutical in a packaging vessel which is equipped at least in part thereof with an oxygen absorbing resin layer wherein an iron-based deoxidizing agent is kneaded with and dispersed in a theremoplastic resin so that oxygen is absorbed in the layer in the presence of carbon dioxide gas and by hermetically sealing the packaging vessel.

Abstract: Wear resistance and oxidation resistance of bioimplantable polymeric parts is improved by packaging the parts within flexible, gas impermeable containers while subjecting the containers and the parts to a relatively high vacuum force. The containers are heat sealed while subjected to the vacuum force such that, upon sealing, hydrostatic pressure is exerted on the part. Following sealing of the packages, the packages and their contents are irradiated to an extent sufficient to sterilize the parts and to promote crosslinking within the part. Alternatively, the same property enhancements can be imparted to polymeric parts by packaging the part within rigid or flexible containers, minimizing the oxygen content within the containers, pressurizing the containers with an inert gas, or with a mixture of hydrogen and an inert gas, to greater than 1.5 atmospheres, and irradiating the part and the container.

Abstract: A method of packaging a food product employing a tray having side walls defining a cavity in an outwardly directed flange extending around the perimeter of the tray, the flange being adapted to receive a pair of membranes to enclose the tray. The lower membrane is the more permeable of the two. It may be attached to a first surface of the flange.
