Dual-Chamber Twist-Mix PETG Bottle with PP Powder Storage Tube

The dual-chamber bottle is engineered for brands that need to isolate an active powder from a liquid base until the moment of use. The design pairs a durable PP outer cap with a separate PP inner chamber that holds powder in complete isolation, while the main body is a clear, lightweight, and shatter-resistant PETG bottle. A simple twist of the cap releases the stored powder into the liquid below, letting the user activate a fresh mix on demand rather than relying on a pre-blended, potentially unstable formula.

This structure is ideal for enzyme powders, freeze-dried actives, peptide boosters, or any ingredient that loses potency once combined with water or other liquids. Typical applications include brightening treatments, exfoliating enzyme washes, and clinical-grade serums where shelf stability is a selling point. The PETG body is recyclable, tasteless, and wear-resistant, supporting both clean-label positioning and everyday handling during shipping and retail display.
