ABSTRACT:
An impact resistant wrapping system for packaging fragile articles is formed in a sheet by sealing, under pressure, two single or multi-layer or laminated flexible membranes having gas or air barrier properties, with cushioning-cellular material such as sponge foam confined in a single airtight cavity defined between the membranes. The wrapping system is in a flat state in which the cushioning-cellular material is constricted in the cavity. In use, the sheet-like wrapping system is wound or folded around the article and is retained in its wrapping state with fastening members. Air is introduced into the cavity by opening an air valve or puncturing the wrapping system at any surface point thereof, so as to allow the cushioning-cellular material to expand and force the inner of the membranes against the article, whereby the article can be securely protected from shock and damage. After use, by removing air from the cavity formed between the outer and inner membranes through the air valve to constrict the cushioning-cellular material, and closing the air valve or applying an adhesive treated surface patch to maintain the compressed state of the cushioning-cellular material in the cavity, the wrapping system can be reused.
