Definitions
- the present invention relates to container labels and, in particular, to a corrosion inhibiting label for metal containers .
- Metal containers for food, beverage, aerosol, industrial products and the like are usually made from steel or tin plated steel.
- the interior of the container is protected from corrosive products by being lined
- containers are then printed or labeled. If the container is printed then the base printing coat protects it from corrosion. If it is labeled, then oxygen permeates the label and oxidizes the metal . In order to prevent the corrosion of the container, the container exterior is usually "wash coated", i.e., a thin coat of resin is applied and then baked on.
- shrink film a shrinkable film which is wrapped around the container and then shrunk on by heat.
- This shrink film is printed on the inside so that the printing inks and/or base coat inks are in contact with the can. If an additional adhesive coat is applied to the inside of the film then the adhesive coat is in contact with the can.
- a corrosion inhibiting label comprising a shrinkable film and printing on the label, wherein a corrosion inhibitor is included in the film or the printing or in both the film and the printing.
- Fig. 1 is an exploded view of a can and a heat shrinkable film label in accordance with the present invention.
- this invention utilizes a shrinkable film label 1, which contains corrosion inhibitors and which is heat shrunk onto a container 2, such as a metal can.
- the label 1 which as is typical, includes printing 3 thereon identifying the product contained in the container and containing related information, stays on the container 1 throughout the product's useful life (e.g., a label on a soup can).
- the heat shrinkable film may be polyethylene, polypropylene, or polyvinyl chloride and contain a corrosion inhibitor such as an amine .
- Another way of making a shrink label is to put the corrosion inhibitors into the base coat ink if a base coat ink, such as is generally used for printing on film, is used. Labels are sometimes partly transparent and therefore a transparent base coat is needed or the film itself will have a corrosion inhibitor. If the label has an adhesive coat, such as thermoplastic on the interior of the label, the anticorrosive inhibitor can be added to the adhesive coat.
- the shrink film label 1 covers the entire surface of the container 2 (except the ends) .
- the top end of the container 4 is usually made separately and is pre-coated. If the bottom end 6 is separate it is also precoated. If the bottom end 6 is integral it is easily protected by a spray coat or a coat applied by other means, which may be ultraviolet and/or heat cured.
- the bottom chime 6 (the edge that contacts a surface when the container 2 is on that surface) can be doubly protected by folding the shrink film around it using a method such as that disclosed in copending Application Serial No. 09/182,546, filed October 29, 1998 and entitled "A METHOD OF APPLYING A HEAT SHRINK FILM TO CONTAINERS AND CONTAINERS FORMED THEREBY", the entire disclosure of which is incorporated by reference herein. This is useful for very corrosive contact such as on wash basins, bathtubs etc.
