Our black PET single wall jars are normal 1-piece jars. They’re called “single wall jars” to distinguish them from the 2-piece double wall jars.
These jars are made of polyethylene terephthalate (PET) plastic, which is of the polyester family and is semi-rigid, and very light-weight. It has high clarity, is strong and impact-resistant. It has a good chemical resistance.
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.
Black PET single wall jars are typically used for lotion, cream, serum, gel, putty, clay, hair products, skin products, cleanser, and other personal care products.
Covers for Black Single Walled Jars are sold separately to allow you to customize the look of your finished product.
