PET and HDPE plastics are very popular for manufacturing bottles and jars.

PET Plastic Bottles

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 colour matched to be any colour.

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 colour 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.

HDPE is a high-density plastic that is very stiff, has a good temperature resistance and a very good water vapour barrier. PET plastics are highly transparent in appearance, available in different colours, lightweight and tough against gases and liquids. PET is also highly resistant to diluted acids, oils and alcohols.
