摘要：An impact resistant wrapping system for packaging fragile articles is formed in asheet by sealing, under pressure, two single or multi-layer or laminated flexible

membranes having gas or air barrier properties, with cushioning-cellular material such assponge foam confined in a single airtight cavity defined between the membranes. Thewrapping system is in a flat state in which the cushioning-cellular material is constricted inthe cavity. In use, the sheet-like wrapping system is wound or folded around the articleand is retained in its wrapping state with fastening members. Air is introduced into thecavity by opening an air valve or puncturing the wrapping system at any surface pointthereof, so as to allow the cushioning-cellular material to expand and force the inner ofthe membranes against the article, whereby the article can be securely protected fromshock and damage. After use, by removing air from the cavity formed between the outerand 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 thecompressed state of the cushioning-cellular material in the cavity, the wrapping systemcan be reused.
