High Density Polyethylene
The International Resin Code for HDPE is
Polyethylene is the world's most common plastic. It appears in three forms: high-density (HDPE), low-density (LDPE) and linear low-density (LLDPE).
(To understand more about LDPE/ LLDPE, see lesson 4.)
HDPE is the strongest of the three Polyethylenes, and is often used in food packaging (for example, in white milk 'bottles').
HDPE's high resistance to chemical corrosion makes it a popular choice for household cleaners.
