Liquid Pouch Bags, Four-Side Seal, for Hydrogen Water and Yogurt

This liquid pouch bag is engineered for export-oriented liquid filling, using a four-side seal format that keeps the pouch flat and stable on automatic filling lines. It can be supplied with a fitment spout, butterfly valve, or tear notch, depending on how the product is dispensed. Common configurations include 300ml hydrogen water pouches and 180g pasteurised active yogurt bags. We customise bag shape, dimensions, seal width and opening position to match your filler, sterilisation process and retail presentation, giving importers a practical format for bulk purchasing.

Laminates are selected from food-grade structures such as PET/AL/PE, PET/VMPET/PE and PET/NY/PE, with barrier, sealing and reinforcement layers balanced against the product's acidity, pasteurisation temperature and shelf-life target. Printing is carried out by 1-8 colour gravure, covering solid backgrounds, gradients and selective matte effects. Standard pouch capacities run from 100ml to 1L, while film thickness and bag dimensions are adjusted to the fill volume. Matching roll film is also available, so importers can supply the same artwork for both pre-made pouches and automatic form-fill-seal lines.

Typical applications include hydrogen water, active yogurt, juices, purees, sauces and personal-care liquids, as well as other food and non-food liquids. Importers can start an OEM/ODM programme by sending samples, drawings or filling-machine parameters; we then confirm material, pouch format, spout and artwork before production. Our Dongguan plant operates cleanroom workshops and 1-8 colour gravure printing lines. With an MOQ of 10,000 pcs, we support full-container shipments and assist with export documentation, packing lists and label data for smooth customs clearance.
