Saran Premium Wrap and Saran Cling Wrap are made with Polyethylene
Microwave Tips: To vent excess steam, turn back one corner of the wrap. For optimal results, use a container large enough to allow an inch between the wrap and the food. To prevent the wrap from melting, food high in fat or sugar should not come into contact with the plastic wrap. Not for use in browning units, conventional ovens, stovetops, or toaster ovens.
