Is it safe to wrap very hot food (above 90 celsius) in plastic wrappers? will the plastic chemicals under high temperature contaminate the food?
Plastic food wrap aka Saran is known as PVDC (polyvinylidene chloride) in the plastics industry. The melting temperature is in the ball park of 165 deg C. So heating it up to 90 should be no problem. Moreover PVDC is FDA cleared for use as a food contact surface as a base polymer, in food package gaskets, in direct contact with dry foods, and for paperboard coating in contact with fatty and aqueous foods. They put a lot of work making sure any plastic that touches food is safe regardless what you do to it.
