The B240AMPCR100 is a 16 oz amber 100% post-consumer resin (PCR) PET plastic bullet round bottle with 24-410 neck finish. This item is made from 100% post-consumer plastic resin, also known as "PCR". PCR is made from recycled items of the same type of plastic, such as water bottles, vitamin bottles, shampoo bottles, and so forth. Using PCR may result in small color imperfections or a grayish hue, but often there is no perceptible difference between items made of PCR and items made of virgin resin. We always recommend obtaining samples before ordering to ensure that the PCR item meets your requirements. The cosmo round, also called bullet round and imperial round, is characterized by its tall and slender build with steeply rounded shoulders. Polyethylene terephthalate (PET) is marked with the resin identification code of 1. PET is of the polyester family and has high clarity, good chemical resistance, high impact resistance, and medium rigidity. PET is also light-weight and is used for products containing essential oils. 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. This item has a 24-410 neck finish. The first number refers to the diameter (in mm), and the second refers to the closure depth, style and thread. This container can be paired with a closure with a matching finish. This container is amber, making it an ideal display container for your product.
