350ml Shaped Aluminum Foil Pouch for Hydrogen-Rich Water | Light-Blocking High-Barrier Liquid Packaging

With 350ml hydrogen-rich water packaging as a typical use case, this shaped foil pouch prioritizes light blocking and high-barrier performance for liquids that are vulnerable to light exposure and gas loss. The pouch can follow a shaped outline and use three-side or four-side seals, producing flat, secure seal edges. A spout, valve or standard tear notch can be added to match filling and drinking methods. While 350ml is a common size, both pouch shape and opening style can be adapted to brand requirements.

The material structure combines aluminum foil or metallized composite film with a compatible heat-seal layer to create the light-blocking barrier. Rotogravure printing runs in 1-8 colors and clearly reproduces brand graphics and product details. Fill capacities span 100ml–5L, with pouch formats such as shaped pouches, spouted pouches and flat pouches. Custom work is accepted from samples or artwork, and matching roll film in the same material is available as a companion supply.

These pouches suit hydrogen-rich water, mineral water, plant beverages and liquid seasonings, as well as powders or pastes that need light blocking and moisture protection. A custom project normally begins with a requirements discussion, then sample or artwork confirmation, proofing, and production after the order is placed. The factory is based in Dongguan, Guangdong, and operates a Class 10000 clean workshop. MOQ is 10,000 pcs, with production scheduled against the approved plan and on-time delivery.
