This a plastic made out of Iodine Table salt. The type of plastic used here is LDPE(Low-density polyethylene). I think this plastic of plastic is used especially for this product because it is tough, flexible and it is transparent so you can see the contents inside and it is easy to process.
LDPE is recyclable but most of the areas do not have the facilities to recycle it so you spend most energy on transporting it where its ought to be recyled. It can be recycled into trash can liners and cans, compost bins, shipping envelopes, paneling, lumber, landscaping ties, floor tile etc
