The B1546NT is a 16 oz natural-colored HDPE plastic dairy bottle with 38-DBJ neck finish. This is a dairy-style bottle, which is often used for milk or juices for multi-serving size and single-serving sizes. If you intend on using these containers for dairy-based products, you should order these in full case quantities. High density polyethylene (HDPE) is marked with the resin identification code of 2. HDPE has a high tensile strength, good resistance to chemicals, good impact resistance, highly rigid, and highly scratch resistant. This item has a 38-DBJ neck finish. This container can be paired with a closure with a matching finish. Natural-colored containers are not actually colored. This is the natural color of the plastic, which is a milky translucent color. This translucent color shows product level, or how full (or, if you're a pessimist, how empty) the container is.
