PET or HDPE – which is better for storing carrier and essential oils?
Essentially, both types of plastic are perfectly suitable for storing carrier and essential oils.
· PET bottles do not have as high-temperature resistance as HDPE containers. While PET bottles have a maximum temperature resistance of 55 °C, HDPE containers have a maximum temperature resistance of 75 °C
· PET containers can handle cold temperatures of about – 40°C whilst HDPE containers can withstand temperatures up to -79°C.
· PET plastics are transparent, lightweight, and highly resistant to diluted acids, oils, and alcohols.
· HDPE is a high-density plastic that is stiff and has a good water vapor barrier. HDPE is known for its strength and durability and this is the reason that we offer bulk sizes of our product in this type of plastic. While they are not as clear as PET plastic, HDPE bottles and containers can be translucent so you can see your product inside the bottle.
