In the next few days, we will mainly talk about the different types of plastic resins. Today we are going to discuss about High Density Polyethylene (HDPE).
HDPE is the plastic resin that is most widely used for plastic bottles. Some of its well-known characteristics are impact-resistant, which makes it durable, and it makes a fine moisture barrier. HDPE is normally FDA-approved so it's safe as containers for foods and drinks. You can be sure when you use an HDPE container that there will be no leaking chemicals into your edible goods. In the triangle that you can find in all plastic products, HDPE is assigned to number 2 (look at the symbol on the right), which means that it is one of the safest plastic resins to consume.
Impact resistant, economical, durable, great moisture barrier, translucent, and flexible.
HDPE is compatible with a lot of different things like food products, acids, and caustics; but not to use with solvents and essential oils.
HDPE containers give great protection for temperatures below 0° and they can also withstand high temperature up to 160°F. However, it is possible to contain products with temperature of 248°F for only limited period.
