Medical Fluid Filling and Sterile Liquid Manufacturing

Flexible Medical Packaging (FMP) provides specialist medical fluid filling, sterile liquid manufacturing and contract fluid blending for healthcare, medical device and infection prevention brands. From small-volume sachets to bulk liquid filling, we combine cleanroom manufacture, regulatory expertise and integrated packaging to deliver compliant, scalable solutions within ISO 13485-controlled quality systems.

How to decide whether you need medical fluid filling

Medical fluid filling is relevant when a healthcare, medical device or infection prevention product needs a liquid formulation to be blended, handled and packed under controlled conditions, with the quality documentation and packaging performance required for its intended use. 

FMP supports products including sterile saline solutions, irrigation fluids, biocidal formulations, wound cleansing solutions, diagnostic and device-associated liquids, and healthcare-grade disinfectants. 

By partnering with FMP, you’ll receive fluid formulation expertise, cleanroom filling, regulatory support and packaging integration to deliver fully compliant, ready-to-market solutions. 

Sterile or non-sterile – which should you choose? 

The correct route depends on the product’s intended use, regulatory requirements, formulation and contamination risk. FMP can help you assess those requirements and define the appropriate manufacturing, filling and packaging approach before production begins.
