Custom 500ml Spouted Liquid Pouch for Plant Nutrient and Humic Acid Solutions

This spouted liquid pouch is designed for measured filling of plant nutrient solutions, humic acid concentrates and similar liquid products. The bag body uses a stand-up three-side or four-side seal construction, with a folded base that keeps the pouch stable once filled, while the side and bottom seals are reinforced for reliable pressure and drop resistance. The top can be fitted with a screw-cap spout, flip-top spout or one-way valve for smooth pouring with minimal dripping, plus optional hang holes, handles or custom spout shapes.

Pouches are built from food-grade multi-layer laminates such as PET, NY and PE, with an inner PE sealing layer suited to liquid contact, balancing barrier performance, flexibility and puncture resistance; the structure and thickness can be adjusted to match your product. Printing uses 1-8 colour gravure printing with clear artwork and consistent colour, including full-coverage backgrounds and matt or gloss finishes. Common capacities run from 100ml to 5L, and matching roll film is available in the same material.

Typical applications include horticultural fertilisers, humic acid and amino acid nutrient liquids, plant growth regulators, food flavour liquids and personal care liquids. For customisation we accept samples and artwork, supporting you from pouch type and print layout through to sampling and mass production. Our factory in Dongguan, Guangdong runs a Class 10,000 cleanroom, with an MOQ of 10,000 pcs and batch inspection before shipment — well suited to export and private label projects.
