Abstract
A multilayer laminate is disclosed. The base layer is a transparent colored layer made of OPS, PET, polypropylene, polyester, or a similar material. The base layer is then metallized by a vacuum process to provide a metallized sheet or film. A second sheet or film is then laminated over the metallized layer. The laminating sheet or film is transparent and may be either clear or have a desired color so that a metallized color is seen on both sides of the sheet. If a colored laminated layer is selected then a different color is seen on each side of the sheet. The sheet may then be converted into a thermoformed tray. The use of a colored laminating sheet provides colors such as gold and metallized blue previously not available at reasonable costs.

U.S. Patent No. 4,825,025 describes a food receptacle for microwave cooking. The receptacle generally has three layers. The uppermost layer is a high heat tolerant protective layer, which ensures that the food product does not touch the metal layer or the substrate. Underneath the uppermost layer is a thin layer of a conductive material. These two layers are mounted on a substrate, preferably paper.
U.S. Patent No. 5,106,670 describes a metallized package component. The component includes at least two layers of a thermoplastic polymeric laminate, which may be bonded together by an adhesive. A metallic layer is disposed on the top surface of the laminate and is visible from both sides of the laminate.
U.S. Patent No. 4,360,551 describes a flexible film laminate. The laminate has a first layer of a heat-sealable polyolefin, a second layer of a previously metallized thermoplastic polymer that is bonded to the first layer, and an adhesive for bonding the metallized surface of the second layer to the first layer.
U.S. Patent No. 4,308,084 describes a laminate for packaging foodstuffs. The laminate has an aluminum substrate. The substrate is laminated to a polyolefin film using a polyolefin resin as an adhesive.

U.S. Patent No. 4,211,822 describes highly reflective multilayer metal and polymer composites.
The composite has a thermoplastic polymer outer layer, one side of which is intimately bonded with a layer of a soft metal. The composite is then formed by a conventional forming process to the desired shape.
U.S. Patent No. 4,936,935 describes a microwave heating material. A metal layer is bonded to a substrate layer, which is then overlaid with an outer lacquer layer. The substrate may be a polymer.
U.S. Patent No. 5,834,046 describes a closure for microwave cooking. The bottom portion of the closure is a lamination. A moisture barrier polyolefin is laminated to a thermoformable substrate, which is typically a polyester.
However, metallized sheet or film has certain disadvantages and limitations. While the metallized layer is located on the bottom of the sheet and not in direct contact with the food product that will be packaged in a tray formed from this sheet, the top of sheet may nevertheless contain particles of metal due to these having rubbed off during the nesting of the trays. Such particles can contaminate the product package on the tray. Additionally, from time to time for different reasons moisture may come into contact with the metallized particles causing the color to change from a shiny bright look to a dirty rusty aspect.
U.S. Patent No. 4,559,266 describes laminated materials for thermoforming into food packaging.
The laminate has a layer of mainly polyolefin, a layer of a polymer, a metal-vacuum deposited layer and a layer of a transparent thermoplastic material.
However, the present metallized sheets provide a bright shiny look such as gold or silver on one side only rather than on both. Thus there ;~ ~r;~i a need to provide a metallized color effects (either of the same aspect or of different aspects) from both sides of the film.
Summary of the Invention It is therefore a principal object of the invention to overcome the shortcomings of the devices heretofore mentioned.
It is a further object to provide colored metallized film and trays.
It is a further object to provide film and trays with metallized colors.
It is a further object to provide film and trays having two sides each with different metallized colors.
It is an object to provide metallized film and 5 trays which do not rub off metal particles upon contact.
It is a further object provide metallized film and trays which do not rust.
The invention is a multilayer laminate. To solve the above problems, a new thermoplastic sheet or film has been developed comprising a base layer of a transparent colored layer, made of styrenic films such as OPS (oriented polystyrene) polyester films such as PET (polyethylene terephthalate), polyolefin films such as polypropylene, polyethylene, PVCs (polyvinyl chlorides) or similar film materials. The base layer is then metallized by a vacuum process to provide a metallized sheet or film. A second thermoplastic sheet or film is then laminated over the metallized layer. The laminating sheet or film is transparent and may be either clear or have a desired color. If a colored laminated layer is selected then a different color is seen on each side of the sheet.
The sheet may then be converted into a thermoformed tray.

It is a further object to provide film and trays with metallized colors.

The invention is a multilayer laminate. To solve the above problems, a new thermoplastic sheet or film has been developed comprising a base layer of a transparent colored layer, made of styrenic films such as OPS (oriented polystyrene) polyester films such as PET (polyethylene terephthalate), polyolefin films such as polypropylene, polyethylene, PVCs (polyvinyl chlorides) or similar film materials. The base layer is then metallized by a vacuum process to provide a metallized sheet or film. A second thermoplastic sheet or film is then laminated over the metallized layer. The laminating sheet or film is transparent and may be either clear or have a desired color. If a colored laminated layer is selected then a different color is seen on each side of the sheet.
The sheet may then be converted into a thermoformed tray.
Accordingly, by laminating a sheet or film (of any of the above indicated categories) over a previously metallized sheet or film, two of the existing problems presently encountered are solved, namely metal particles rubbing off on food and the rusting of the metal trays themselves.
Furthermore, the invention provides the commercially desirable possibility of a new combination of metallized colors, heretofore not available at reasonable costs. Additionally, the new type of sheet may be converted into -thermoformed trays in preferred embodiments of the invention.
Detailed Description of The Preferred Embodiments of The Invention.
Those skilled in the art will gain an appreciation of the invention from the following discussion of the preferred embodiments of the invention.
Figure 1 shows a schematic of a preferred embodiment of the invention. The laminating sheet or film according to the present invention can be made by the following procedure.
A first transparent colored layer 10, made of OPS, PET, polypropylene, or a similar material is covered on one side with a metallized layer 12.
Metallized layer 12 of the invention is a metal-vacuum deposited layer. Methods for forming a vacuum deposited or sputtering layer 12 of aluminum, tin, zinc and/or other metals on the surface of a plastic resin film substrate are known per se. That is the metal is vacuum deposited or sputtered in an inert gas such as argon on the substrate. Usually, aluminum is used to form layer 12 .
A third layer 14 is then laminated over the metallized layer. The laminating sheet or film 14 is preferably transparent and may be either clear or have a desired color. If a colored laminated layer is selected then a different color is seen on each side of the sheet. There is no limitation on 15 the layer 14 as used herein so long as it is transparent or translucent enough to show the metallized layer underneath.
The laminate of the invention possesses a decorative effect due to the metallized layer's 12 20 luster which is seen through layers 10 and 14. The invention provides the possibility of a combination of numerous metallized colors. For example, if one wanted a gold appearance on one side, and a silver appearance on the other side, 25 there could be a combination of an amber transparent layer with aluminum sputtered on to the layer with a clear layer laminated over the metallized layer. The invention provides the benefit of a film with two different metallized colors appearing from either side.
Additional effects are added when layer 14 is colored so that there is a colored decorative effect on both sides. An important feature of the tray is that the metal layer should be of sufficient thickness to provide a metallized appearance through the transparent colored layer and so that two different colored views may be obtained when looking at either side of the laminate rather than a mixing of colors.
In alternative embodiments, layers 10 and/or 14 may comprise a translucent or iridescent material for alternate aesthetic effects.
The laminated material of the invention is useful as a packaging material or may be used for thermoformed trays. Methods of manufacturing thermoformed trays are well known to those skilled in the art.
20 Thus by the present invention its advantages will be realized and although preferred embodiments have been disclosed and described in detail herein, its scope should not be limited thereby rather its scope should be determined by that of the appended 25 claims.
Furthermore, the invention provides the commercially desirable possibility of a new combination of metallized colors, heretofore not available at reasonable costs. Additionally, the new type of sheet may be converted into -thermoformed trays in preferred embodiments of the invention.
