In hopes of creating a new biodegradable option for food wrapping,
they came up with this.

    Paper, plastic, or crab?
    July 29, 2018

   Researchers at the Georgia Institute of Technology have developed [46]a
   compostable material derived from crab shells and tree fibers that
   might not only be able to replace plastic wrap but could even do a
   better job keeping food fresher for longer than currently available
   non-nature-derived plastic wrap.

My quesrtions were:
1- Could they be used for hot foolds al pi din?

2- If yes, would anyone actually do so? I can see hekhsheirim shying away
for policy ("heim lo yaaminu li") reasons.

3- Foods are rarely "seran wrapped" at had soledes bo temperatures anyway.
(I think the more environmental - less clingy actual Seran brand wrap
of the past few years couldn't handle the heat anyway.)

Do you have to be shocheid that maybe a store wrapped the prepared food
you just bought for Shabbos in crab wrap while still hot? (Assuming "no"
to #1.)

Tir'u baTov!
