| 摘要 |
A device, comprising a laminate pad packaging inclusion, fabricated from a composite of fabric materials, permeable to gases and containing a formulation, including sodium carbonate peroxyhydrate or sodium perborate, which is capable, on hydration, of both generating oxygen and absorbing carbon dioxide, being designed to maintain a predetermined respective percentage composition of oxygen and carbon dioxide in both MA and CA packed foods, by actively compensating for changes within the pack atmosphere. The active chemicals may be bonded to a carrier web using an adhesive applied in a grid pattern. |
