ABSTRACT:
A continuous, two-ply thermoplastic film material, sealed in a manner that forms superimposed panels into individual, inflatable bags that are repeated and separable, individually or in groups of bags, forms a continuous packaging material. The material can be cut or torn from preformed rolls to a desired size to over-wrap a product with an air cushion. Valves are sealed into the material at repeated locations to allow air insertion at any location or to allow a primary air chamber to feed any length of pre-sealed bag material that can be sectioned and filled with air at the same time. The invention also allows wrapping of a product first, without air, and insertion of the wrapped product into a carton or box with provision for inflating the wrapping to conform tightly to the product, inside the carton or box. The wrapping material can be recycled either as a reusable, inflated wrapper or made of biodegradable plastic materials to minimize environmental damage.
