Our first post in a series designed to educate you in packaging.
PET and HDPE plastic bottles are very popular for manufacturing packaging bottles and jars. However, understanding why to use each plastic type is very important to many brands and some consumers.
Within this article, we will explore, why and how to compare each plastic type.
PET is also known as PETE or Polyester. PET stands for Polyethylene Terephthalate and is mostly used for the manufacturing of plastic bottles for liquid or beverage consumption. PET is also used for many disposable plastic containers that are also used for ready made or frozen foods. PET is popular because it provides a sound oil barrier which helps with chemicals attacking the plastic. PET can also be very clear plastic and can look like glass once set to its desired shape. PET can also be color matched to be any color.
Temperature range
PET bottles do not have as high of a temperature resistance (less than 131°F) as HDPE. PET containers can also handle cold temperatures of about -40°F.
HDPE Plastic Bottles
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) plastic is one of the most common plastics used in manufacturing, HDPE is known for its durability and strength. While not as clear as PET plastic, HDPE bottles and containers can be translucent so you can to see your product inside the bottle. This type of plastic can also be color matched and is popular in white.
Temperature Range
HDPE bottles and containers also are able to withstand colder and freezing temperatures very well (-110° F) and higher temperatures moderately well near 167°F.
