350 ml Four-Side-Seal Hydrogen-Rich Drinking Water Spout Pouch | Nylon Four-Layer Aluminium-Plastic Laminate with Screw Cap

Designed for hydrogen-rich water packaging, this four-side-seal pouch is named at 350 ml, while the specification table covers 1–10 L. A nylon layer is incorporated into the aluminium-plastic laminate to create a four-layer build, and the pouch is finished with a spout and screw cap. The nylon is added to improve puncture and flex resistance, helping small filled water pouches withstand handling and stacking.

In a four-layer laminate, each layer has a typical role: the outer layer supports printing and abrasion resistance, the nylon layer contributes toughness and puncture resistance, the foil layer blocks light and oxygen, and the heat-seal inner layer keeps seams tight while contacting the contents. Additional layers can improve mechanical protection, but they also place higher demands on lamination consistency.

Printing can run from 1 to 8 colours. Capacities span 1–10 L, the fitting is a spout with screw cap, and the MOQ is 10,000 pcs. Pouch dimensions, spout diameter and seal width can be customised; artwork is produced from the customer's supplied file.

Typical use covers hydrogen-rich water and drinking water products, as well as juice, soup stock and other liquid foods that need protection from light. The four-side-seal format has a crisp shape and stacks neatly during carton packing.

Kody Packaging carries out production in Dongguan, Guangdong, with printing, lamination, slitting and pouch making linked in sequence. A sample can be made from a reference pouch to check interlayer bond strength and seam performance before bulk production.

Because the nylon layer changes material consumption and processing time, quotations are based on the approved sample. If the fill requires stronger mechanical protection, please state the usage and transport conditions when ordering.
