Liquid Pouch Bags 500ml Graduated For Lab Sampling

Positioned for laboratory sampling and liquid dispensing, this liquid pouch bag is available in stand-up or flat three-side-seal formats, heat-sealed for reliable performance. It can be fitted with spouts, screw caps or valves to suit different filling and emptying methods. Graduation marks can be printed on the pouch body for convenient observation and sampling at volumes such as 500ml. The finished seals are flat and strong, making the pouch suitable for overseas importers and brand owners developing custom liquid packaging programmes.

The laminate can be built with food-grade PET/PE, PET/AL/PE or PET/NY/PE structures according to the liquid being packed, with an inner heat-seal layer for reliable sealing and content resistance. Printing is done by 1-8 colour gravure printing, allowing brand artwork, graduation marks and usage instructions to be reproduced clearly. Standard capacities span 100ml to 5L, and matching roll film is available for automatic filling lines. Export orders can be adjusted by film thickness, pouch style and print colours to suit different market requirements.

Applications include laboratory water sampling, household and personal care liquids, food sauces, agrochemical samples and industrial liquid dispensing. For customisation and OEM/ODM programmes, we accept artwork from samples or drawings, confirm pouch style, material, capacity and print layout, then arrange sampling and production. Our factory is based in Dongguan, Guangdong, with cleanroom production and ISO 9001:2015 and ISO 14001:2015 management systems. MOQ is 10,000 pcs, with full-container shipping and export documentation support for overseas importers, brand owners and distributors.
