High Density Polyethylene (HDPE) is one of the common polymers that have been used in the industrial sector. HDPE has been classified as Polyethylene (PE) group and differentiate by other PE based on their crystallinity and branching of the PE. HDPE are produced by insertion polymerizations with transition metal catalysts . HDPE was first observed in 1954 by Karl Ziegler’s group in Germany and by Standard Oil and Philips Petroleum in the United States where the production started in 1957 in Germany, Italy and the United States . Plastics come from oil, which were converted into small and tiny pieces called resin. Plastics come as a by-product of oil refining, and uses only 4% of the total world’s oil production. The most common of plastics containers are made from HDPE . Compared to Low Density Polyethylene (LDPE), HDPE finds utility where hardness, rigidity and higher strength are important. HDPE containers generally have a low melt index usually less than 1.5 . Compared to the other type of PE, HDPE has the highest density with the highest stiffness and lower permeability. These combinations of properties make HDPE suitable for many small, medium or even large liquid containment applications such as milk and detergent bottles, pails, drums and chemical storage tank . Besides that, HDPE are widely used as the packaging materials, piping materials, food storage containers, trash cans and also toys.
