===LDPE===

===LDPE===

Low Density Polyethylene, made from the polymerization of monomer ethylene or ethene units. An organic peroxide is used as the catalyst, and high temperates and pressure is used resulting in extensive side branching off the chain (about one chain every 50 monomer units). Because of these chains the polymer fibers are unable to be compacted against each other resulting in lower density and increased flexibility. LDPE is commonly used in cellophane.
