Yupo paper

It has been brought to my attention that many new publications are
being printed on something called "yupo" paper
<URL:http://yca.yupo.com/>. It appears to be a plastic or at least a
plastic coated surface. Has anyone attempted repairs on this
material and do they deviate from standard mends i.e. mulberry paper
and PVA or wheat paste? Are there archival concerns or advantages?

    **** Moderator's comments: There is a FAQ at
    <URL:http://europe.yupo.com/public/faq/>, which describes Yupo
    this way:

       "YUPO is a full line of synthetic printing papers
        manufactured entirely from polypropylene resins. YUPO
        contains no wood pulp or other organic materials."

Skeptical of strange polymers,
