What is LDPE made of?
Low-density polyethylene ( LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. Its manufacture employs the same method today. The EPA estimates 5.7% of LDPE ( recycling number 4) is recycled in the United States. Despite competition from more modern polymers, LDPE continues to be an important plastic grade. In 2013 the worldwide LDPE market reached a volume of about US$33 billion.

LDPE is defined by a density range of 917–930 kg/m 3. At room temperature it is not reactive, except to strong oxidizers; some solvents cause it to swell. It can withstand temperatures of 65 °C (149 °F) continuously and 90 °C (194 °F) for a short time. Made in translucent and opaque variations, it is quite flexible and tough.
How much of LDPE is recycled?
Its manufacture employs the same method today. The EPA estimates 5.7% of LDPE ( recycling number 4) is recycled in the United States. Despite competition from more modern polymers, LDPE continues to be an important plastic grade. In 2013 the worldwide LDPE market reached a volume of about US$33 billion.

Is LDPE stronger than HDPE?
Made in translucent and opaque variations, it is quite flexible and tough. LDPE has more branching ( on about 2% of the carbon atoms) than HDPE, so its intermolecular forces ( instantaneous-dipole induced-dipole attraction) are weaker, its tensile strength is lower, and its resilience is higher.
