Abstract: A material and method for making the material for shrink wrapping articles is disclosed. The material includes an outer shrinkable, stretchable film which is bonded to an inner layer consisting of a nonwoven fabric. A block copolymer hot melt adhesive is used to secure the film layer to the nonwoven fabric layer. The adhesive layer includes an additive which releases a vapor, such as a vapor corrosion inhibitor, which protects and/or treats the product wrapped by the material.
Abstract: An adhesive mixture includes a block copolymer hot melt adhesive and particles of a vapor corrosion inhibitor mixed therein to protect products against corrosion. The adhesive is used to seal flaps of containers together, secure carpet to the floor of a vehicle, secure nonwoven fabric to a shrink film so that the additive is released when the shrink film is shrunk around a product to be protected, or used as an adhesive on a tape, so that the product is protected when the tape is wrapped around the product.
Abstract: A method and material for shrink wrapping articles includes wrapping the article with a shrink wrapping material having a shrink/stretch film outer layer and an inner layer of a non-woven fabric. The shrink/stretch film responds to heat by shrinking around the article being wrapped, while the non-woven material aerates to form bubbles thus acting as a cushion between the shrink/stretch film outer layer and the article being wrapped. Accordingly, the article being wrapped is protected during the shrinking process, and is also protected from hurled objects while the article is being transported. The nonwoven layer may be treated with chemical additives to control the environment in which the article is wrapped and/or to indicate tampering.
