Abstract

The present invention provides a product packaging system in which a foamed polymeric material is provided with a skin of filmic polymeric sheet material covering part or all of the foamed polymeric material, thereby conferring beneficial properties upon the skinned foam. In one embodiment, a fragile or sensitive item is placed upon the foamed material before the skinning process, thereby providing a protective package for the fragile or sensitive item. Skinning may be effected by applying vacuum. The polymeric materials may be biodegradable or soluble. The filmic polymeric material may be applied to two or more separate pieces of the foamed material during the skinning process, thereby hingedly interconnecting those pieces. The level of vacuum and the composition of the filmic material determine the degree of peelable attachment of that material to the foamed material.

NOVEL PACKAGING SYSTEMS
DESCRIPTION
This invention relates to packaging systems.
It is known from the prior art that skin packing processes have already been disclosed as a method of packaging.
In WO95/21105, a skinning process is described by which an article to be contained is placed upon a backing layer preferably comprising a substantially planar porous board or polyvinyl alcohol sheet and skinned with a film of water soluble or water dispersible material, thereby allowing the package to be repulped or composted after use.
In W02004/033297, a similar skinning process is described following which the planar sheet is folded into an erected container or package, in which the polymeric skinning film is water-soluble or water-dispersible and is selected and arranged such that twisting the product and overlying film about an axis transverse to the planar sheet shears the polymeric film generally around the perimeter of the product adjacent the planar sheet, thereby allowing the consumer to dose the product into an essentially aqueous environment without ever coming into contact with the product.
According to the present invention, there is provided a product packaging system in which a foamed polymeric material is provided with a skin of filmic polymeric material covering part or all of the foamed polymeric material.
While the present invention is susceptible of embodiment s in many different forms, this disclosure will describe at least one preferred embodiment, and possible alternative embodiments of the invention with the understanding that the present disclosure is to be considered merely as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the specific embodiments illustrated.
In one application of the invention, fragile items can be protected by means of a skinning process in which the filmic polymeric sheet ("the sheet") is drawn down over an object to be protected which is already resting upon a foamed polymeric substrate ("the foam"). The foam may have been moulded in a previous process in order to receive the contours of the fragile item to be protected or it may simply be an unmoulded block of foam. In either case, the sheet is drawn down on to the foam such that the sheet creates a skin over the exposed surfaces of the foam. The sheet may be heated before being drawn down on to the foam.
Preferably, the foam contains within its mass interstices which may be open bubbles, airways or fissures sufficient to make it porous to the passage of air such that, when a vacuum or partial vacuum is applied to the foam, air is drawn through the foam thereby drawing the filmic polymeric sheet down on to the exposed surfaces of the foam.
It will be apparent to anyone skilled in the art that many beneficial properties are obtained by skinning a porous foamed polymeric substrate with such a skin.
s In the case where the sheet has been selected with this in mind, the sheet will adhere to the exposed surfaces of the foam, giving the foam increased abrasion or scuff resistance, and increased puncture resistance.
In the case where the sheet has food contact approval from agencies such as the U.S. Food Development Agency (FDA), the presence of the sheet covering the exposed surfaces of the foam allows food to be placed in contact with the skin of the foam which may not itself have food contact approval.
The sheet may be peelably adhered to the foam. In this case, the sheet may be removed by peeling from the foam and replaced by a new second sheet using the same process, thereby allowing the foam to be re-used.
A fire retardant can be incorporated into the sheet which then provides both an external barrier to fire penetration of the foam entrapping the available air within the foam, making it unavailable to feed a fire.
The sheet may also confer non-static properties upon the foam.
The sheet may also confer chemical or solvent resistance or perfume or odour barrier property upon the foam.
In order that the invention may be more fully understood, preferred embodiments of the invention will now be described, by way of example: In a first embodiment of the invention, a polymeric foam material in a preformed shape is draped with the polymeric film which has been pre-heated to a malleable state. A full or partial vacuum is then applied to the base, or that part of the outer surface that is not covered by said polymeric film, and the air between film and foam drawn through the foamed substrate. The hot film is consequently pulled down into contact with the foamed substrate at all points of the surface, with the exception of that part of the surface through which the air is drawn, thus forming a skin' on the polymeric foam substrate.
In a second embodiment of the invention, the porous foamed material is divided into two or more pieces such that after the filmic sheet has been drawn down upon the foamed material, the filmic sheet can act as a hinge allowing the different pieces of foamed material to be closed around the object to be protected.
In a further application of this embodiment, two or more pre-formed pieces of foamed material are placed edge to edge along a straight side and a skin formed as described above. By this means, a shell' or 'clam' pack is produced wherein the two or more foamed pieces are united along a common side by the polymeric film skin and may be subsequently closed around the object to be protected, the skin along the common side forming the hinge.
In a further application, an item, for example a fragile or sensitive item, requiring protective packaging, is placed on or within a pre-formed polymeric foamed substrate and a sheet of polymeric film is formed as s described above. In this case the product is held tightly against or within the foamed substrate by the skin. It will be appreciated that in the case where the foamed substrate and the sheet are both water-soluble or water- dispersible, a fragile or sensitive item which has been packed in this way may subsequently be dosed into an essentially aqueous environment without the need for the item to be unpacked. Similarly, where the foamed substrate and the sheet are both biodegradable, the complete pack may be composted after use without the need to separate the sheet from the foamed substrate.
In a third embodiment of the invention, the foamed polymeric substrate is not a single piece of pre-moulded foamed material, but is in the form of sheets or small pieces of foamed material, even recycled waste material.
In this embodiment, the skin is used to collate or package the foamed material for transport and storage within a minimum volume. The softer the foamed material, the greater will be the reduction in volume.
In a further application of this embodiment, a water soluble polymeric film is used. The pieces of polymeric foamed material are preferably soft foam as used to fill articles such as upholstery or soft toys, where the maximum amount of foamed material must be filled in order for the article to maintain its shape. The foam stuffing is surrounded by the heated or unheated water soluble film and a vacuum drawn through one or more openings in the film. The vacuum removes the air and compresses the foam to a minimum volume. At this point, the one or more openings are sealed by any suitable method. One or more of these filled evacuated packs are then placed inside the S article until the article has been completely filled at which point the article is closed. The article is then subjected to steam or water which permeates its outer surface and dissolves the water soluble film, thereby releasing the vacuum. The foam stuffing is then allowed to decompress filling out the article that it has been contained within.
As will now be understood, the present invention provides a product packaging system in which a foamed polymeric material is provided with a skin of filmic polymeric material covering part or all of the foamed polymeric material.
Example:
The foamed polymeric substrate is made substantially from expanded polystyrene foam and the filmic polymeric sheet is made substantially from polyvinyl alcohol, either by extrusion or by casting from aqueous solution, and be preferably of a thickness between 30 and 75 microns, such as those films marketed by Adept Polymers under reference C-10. The filmic polymeric sheet is heated using infra- red heating elements operating at a temperature of 500 C in order to provide a temperature of 120 C at the surface of the polymeric sheet. A vacuum is applied from beneath the expanded polystyrene substrate as soon as the heated polymeric sheet has been draped upon the substrate.
