<p>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 (2, 3) having gas or air barrier properties with confining cushioning-cellular material (5) such as sponge foam in a single airtight cavity defined between the membranes, thus maintaining the wrapping system (1) in its flat state in which the cushioning cellular material (5) is constricted in the cavity. In use, upon winding or folding the interconnectible sheet-like wrapping system (1) around the article and retained in its wrapping state with fastening means (7,8,9,10,11,12,13,14), air is introduced into the cavity by opening an air valve (15) or puncturing the wrapping system at any surface point thereof, so as to allow the cushioning-cellular material to expand and force the inner membrane (2) 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 (2,3) through the air valve to constrict the cushioning-cellular material (5), 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 re-used. <IMAGE></p> |
