A label (as distinct from signage) is a piece of paper, plastic film, cloth, metal, or other material affixed to a container or product, on which is written or printed information or symbols about the product or item. Information printed directly on a container or article can also be considered labelling. Labels have many uses, including promotion and providing information on a product's origin, the manufacturer (e.g., brand name), use, safety, shelf-life and disposal, some or all of which may be governed by legislation such as that for food in the UK or United States. Methods of production and attachment to packaging are many and various and may also be subject to internationally recognised standards. In many countries, hazardous products such as poisons or flammable liquids must have a warning label. Uses Labels may be used for any combination of identification, information, warning, instructions for use, environmental advice or advertising. They may be stickers, permanent or temporary labels or printed packaging. Products Permanent product identification by a label is commonplace; labels need to remain secure throughout the life of the product. For example, a VIN plate on an automobile must be resistant to heat, oils and tampering; similarly, a food label must endure until the food has been used. Removable product labels need to bond until they are removed. For example, a label on a new refrigerator has installation, usage and environmental information: the label needs to be able to be removed cleanly and easily from the unit once installed. Labels for food and beverages typically include critical information pertinent to the contents or ingredients used in a product, and may also state allergy risks such as the presence of gluten or soy. For example, the United States Food and Drug Administration (FDA) provides standards to regulate the information provided on the labels and packaging of wine and spirits. These labels include information like brand name, class and type designation, and alcohol content. Packaging Packaging may have labeling attached to or integral to the package. These may carry pricing, barcodes, UPC identification, usage guidance, addresses, advertising, recipes, and so on. They also may be used to help resist or indicate tampering or pilferage. Assets In industrial or military environments, asset labeling is used to clearly identify assets for maintenance and operational purposes. Such labels are frequently made of engraved Traffolyte or a similar material. They are usually tamper-evident, permanent or
