PE

PE (HDPE) is the workhorse of opaque bottles: chemically resistant, tough enough to survive drops, and naturally matte, with no glass-like gloss to compete with the label. Unlike PET and PETG it blocks light, so it suits actives that degrade on the shelf, and it stays cost-efficient at large volumes. Typical bottles: shampoo, conditioner, body lotion, body wash and light-sensitive formulas.
