Our cobalt blue PET single wall jars are normal 1-piece jars. They’re called “single wall jars” to distinguish them from the thicker 2-piece double wall jars.
These single wall jars are made of polyethylene terephthalate (PET) plastic, which is of the polyester family. It is a semi-rigid plastic, which is very light-weight. It has high clarity, is strong and impact-resistant with a good chemical resistance.
We advise you to avoid using PET containers to store products that contain essential oils greater than 5% or fragrance oils greater than 15%. If your oil percentages exceed these respective levels, please consider using glass.
Our cobalt blue PET single wall jars are a great choice for lotion, cream, serum, gel, putty, clay, hair products, skin products, cleanser, and other personal care products.
Covers for cobalt blue PET single wall jars are sold separately to allow you to customize the look of your finished product.
