A lightweight clear material produced in very thin thicknesses that can be used for covering foods being stored or prepared. The characteristics of this material enable it to shaped easily, cling well to containers, repel or retain moisture, and to withstand relatively high levels of heat when microwaving foods, but not for use in ovens. It is available in various thicknesses that enable it to be used for different needs, such as storing some foods longer or more securely. Polyethylene is the most common substance used to make the plastic wraps with several other materials also available from manufacturers, such as polyvinylidene chloride and polyvinyl chloride.
