Collapsible water pouch

Made from a food-grade TPU and PE composite film, the edges are sealed using high-frequency heat welding, ensuring high seam strength. The bag features an accordion-style folding structure with reinforced ribs at the folds. The water inlet consists of a wide-mouth screw cap with a silicone sealing ring. The handle is a combination of webbing and rigid plastic, fitted with metal hardware. The material is freezer-safe and remains flexible without becoming brittle at low temperatures. The water outlet features a push-to-dispense valve.
