-
The rigid nature of HDPE allows manufacturers to use it for food product and chemical containers. Other uses for HDPE include trays, cutting boards, pipe fittings and tanks.
Common Uses of LDPE
-
The flexible nature of LDPE lends itself to films. Manufacturers produce plastic bags from LDPE. Other uses include wash bottles and tubing.
Economic and Environmental Impact
-
According to the American Chemistry Council's Resin Production and Sales Stats report, released in November 2009, HDPE is the most common plastic and LDPE is the fifth most common plastic produced in the U.S. The slow rate at which plastic degrades vs. the amount produced makes the disposal of it an environmental issue.
