what is made out of saran
Plastic wrap, also called cling film or cling wrap, is a thin, plastic film used mainly for covering food items to keep them fresh. It was invented in 1953 by a scientist attempting to create a thick plastic covering for his car. GladÂ® Wrap and Saranâ¢ Wrap are the two most well known brands worldwide and are often used as generic terms. The first plastic wrap on the market was made of polyvinylidene chloride (PVC), commercially known as Saran, though today many brands â including Saranâ¢ Wrap â are made of low density polyethylene (LDPE).
