    Characteristics
    Chemically inert, pH neutral, and water repellent, especially if seams are sealed. It is non-abrasive if clean. Some manufacturers use talc or other release agents which create a residue or oily film. Especially true of material with recycled content. "Virgin" grade is non-recycled, "UDSA" grade has been determined safe for storing food. Less expensive than MarvelsealŪ but less effective as a barrier to gaseous pollutants.
