The 300 cc white HDPE pill packer bottle with 45-400 neck finish. This container is a pill packer bottle with a wider mouth than normal pill packers. Packers come in a variety of sizes, but they are typically "squatty" in shape with a wider mouth. Packers are used extensively for pills, capsules, supplements, powders, and other health-related products. 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 45-400 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 an opaque white, and well-suited for products with contents that don't need to be displayed. This white container is an excellent canvas for a label or print.
