2D Single-use bags

Applicable throughout all process steps in biopharmaceutical production, from 5ml to 50L


  • Customizable to various processes
  • Low extractables and precipitation
  • Gamma-sterilizable





An alternative to bioprocess bags for storage, sampling and transfer and shipping of liquids in all process steps
Depending on your production scale, we supply the right size bag for an optimal process.

The 2D Bags are available in the following volumes: 5ml, 50ml, 100ml, 250ml, 500ml, 1L, 2L, 5L, 10L, 20L, 35L, 50L.
If your production requires other volumes or dimensions, ROMYNOX supply a custom made bag based on your specific needs.

Even with small orders, ROMYNOX can assist you. Depending on your needs, we can supply the 2D Bags with different volumes, tubing’s, connectors and assemblies.. The scalability of the 2D Bags allows you to use them throughout the entire biopharmaceutical manufacturing process. Usable from upstream to downstream production (e.g. media and buffer storage, transfer after filtration, storage of intermediates and storage of stock solution).


Renolit 9101 films are made up of five layers. ULDPE and EVOH prevent the ingress or egress of oxygen, carbon oxide and moisture. LDPE and HDPE guarantee high process reliability. A visual overview of the composition layers is illustrated below.

The 2D single-use bags minimize the risk of cross-contamination and significantly increase safety. Cleaning and sterilization is not required and production efficiency is improved. In addition, it reduces the cost of QC and cleaning verification.
