 LDPE is defined by a density range of 0.**0–0.**0 g/cm³. It is not reactive atroom temperatures, except by strong oxidizing agents, and somesolvents cause swelling. It can withstand temperatures of *0 °C continuously and *5 °C for a short time. Made in translucent or opaque variations, it is quite flexible, and tough but breakable.

LDPE has morebranching (on about 2% of the carbon atoms) thanHDPE, so itsintermolecular forces (instantaneous-dipole induced-dipole attraction) are weaker, itstensile strength is lower, and itsresilience is higher. Also, since its molecules are less tightly packed and less crystalline because of the side branches, itsdensity is lower. LDPE contains thechemical elementscarbon andhydrogen.
