3D bioprocessing bags are cubic, freestanding single-use containers for large-volume fluid handling in biopharmaceutical manufacturing. SeamlessBio supplies them from EU stock in volumes from 50 litres to 3,000 litres — RENOLIT 9101 multilayer film, certified to USP <87>/<88> Class VI, gamma-sterilised (ISO 11137, SAL 10⁻⁶), ISO Class 7 cleanroom. No minimum order. Full GMP documentation with every lot.
Pilot scale through commercial production — one supplier, one documentation package, one contact for the full volume range.
ULDPE/LLDPE fluid-contact layer, EVOH gas barrier, outer PE. USP <87>/<88> Class VI certified, ISO 10993 compliant. Controlled extractables profile.
Cubic design sits in standard stainless-steel support frames and cages. Stable footprint for bulk fluid hold, cold storage and large-volume chromatography feed.
3/8" and 1/2" PCS/TPE tubing; male insert, AseptiQuick G, luer-lock, end plug — standard and custom configurations available.
3D bioprocessing bags — also called cube bags — are the single-use container of choice wherever large volumes need to be stored, transported or transferred cleanly in a biopharmaceutical process. Their freestanding, cubic geometry allows them to sit in standard stainless-steel support frames or custom cage systems, making them a direct replacement for rigid tanks in buffer hold, bulk product storage and large-volume chromatography feed applications.
Unlike 2D pillow bags, 3D bags do not require a flat surface or rocking platform — they stand independently once filled. This makes them practical for GMP buffer suites, cold rooms and large-scale downstream processing areas where floor space is managed carefully.
SeamlessBio 3D bags use the same RENOLIT 9101 film platform as the 2D range — same certifications, same extractables documentation, same GMP documentation package. This simplifies supplier qualification when both formats are used in the same facility.
SeamlessBio 3D bags are manufactured from RENOLIT 9101 multilayer film — a controlled-extractables platform used across regulated biopharmaceutical manufacturing in Europe and the US. The same film is used in both the 2D and 3D ranges, allowing a single extractables data package to cover both formats in a supplier qualification dossier.

3D bags are typically supplied in 2-port or 3-port configurations. Port selection determines connection to pumps, sensors, filters and downstream equipment. Standard configurations are in EU stock; non-standard assemblies are sourced with a 3–5 week lead time.
Standard high-flow port for bulk fluid transfer and pump connections. The most common configuration for buffer hold and chromatography feed.
High-flow port for high-volume transfer at commercial scale. Reduces transfer time for 500 L+ volumes. Available in standard 3-port layouts.
Aseptic quick-connector for closed-system integration — sterile connection and disconnection without opening the fluid path to the environment.
Polycarbonate-based silicone tubing for peristaltic pump integration. Standard in media hold and large-volume buffer transfer applications.
Thermoplastic elastomer tubing — preferred for aggressive buffer formulations and processes using organic solvents or low-pH solutions.
Sealed port for unused connections. Maintains sterility during transport and storage of pre-filled or staged bags in cold storage.
A vaccine producer moves from Phase II pilot batches (100–200 L) to Phase III commercial runs (1,000–3,000 L). Supplier A from the US quotes 10 weeks and a pallet minimum. SeamlessBio ships from EU stock — same documentation at 100 L as at 3,000 L, no lead time premium for smaller runs during the scale-up phase.
A CDMO running parallel client programmes needs 500 L buffer hold bags for three different projects in the same week — each with its own CoA, lot documentation and client-specific labelling. One EU supplier, one qualification, delivered on the same day.
A biologics manufacturer eliminating stainless-steel buffer prep tanks needs 200 L and 1,000 L 3D bags for buffer hold between chromatography steps. No cleaning validation, no cross-contamination control between batches. Single-use from EU stock with full cleaning validation replacement documentation.
An advanced therapy manufacturer scaling AAV vector production to 500 L bioreactor runs needs large-volume upstream media hold and harvest collection bags. Clinical-grade documentation for regulatory submission, EU delivery within 5 business days.
Regulatory submissions require material documentation. SeamlessBio provides this as standard — not on request, not at extra cost.
3D and 2D bioprocessing bags serve different process steps. The format determines mixing behaviour, storage geometry and volume range. Using the wrong format creates process incompatibilities that require validation rework.
| Criterion | 3D Bag (cube bag) | 2D Bag (pillow bag) |
|---|---|---|
| Volume range | 50 litres – 3,000 litres | 50 mL – 50 litres |
| Geometry | Cubic / freestanding — sits in stainless steel cage or support frame | Flat / pillow — lays on flat surface or hangs |
| Mixing | Paddle or impeller-driven mixing via integrated port; or gravity-fed transfer | Excellent on orbital shakers and rocking platforms |
| Primary use | Large-volume buffer hold, bulk transfer, upstream/downstream integration | Media prep, buffer mixing, intermediate product hold, chromatography feed |
| Typical users | Commercial biopharma, large-scale vaccine production, biologics manufacturing, CDMOs | Clinical ATMP, CROs, process development, pilot vaccine batches |
| Storage | Requires cage/frame infrastructure; cold room compatible | Flat — hangs in use, stacks in storage |
| Film material | RENOLIT 9101 multilayer (same certification basis) | RENOLIT 9101 multilayer (same certification basis) |
3D bags are specified wherever large-volume, closed-system containment is needed in a biopharmaceutical process. Key steps where 3D bags replace rigid stainless-steel vessels:
Equilibration, wash and elution buffers prepared and held in 3D bags, dispensed directly to chromatography columns via peristaltic pump. No CIP, no tank cleaning between batches.
Clarified harvest or partially purified intermediate held in 3D bags between process steps. Cold-room compatible, with full closure between steps and lot-specific CoA documentation.
500 L to 3,000 L loading volumes fed from 3D bags to large-scale protein A, ion exchange or mixed-mode columns. Gravity or pump-assisted, closed-system transfer.
Tangential flow filtration retentate and permeate collected in 3D bags for hold and further processing. Replaces stainless retentate tanks in single-use TFF configurations.
Large-volume media hold for AAV or lentiviral vector production bioreactor runs. GMP documentation for IND/IMPD submissions included as standard.
Purified water and WFI staged in 3D bags for buffer preparation suites. Closed-system fill, hold and dispense — eliminates open vessel contamination risk at water dispensing.
There is no minimum order at SeamlessBio. You can order a single bag — whether that is a 50 L pilot bag or a 2,000 L commercial-scale container — or a full pallet. Same pricing structure, same documentation, regardless of quantity.
50 litres to 3,000 litres in the standard range from EU stock. Custom volumes outside this range are available on request with a production lead time. Contact SeamlessBio with your volume requirement for a stock and lead time confirmation.
RENOLIT 9101 multilayer film — the same platform used in the 2D bag range. ULDPE/LLDPE fluid-contact layer, EVOH gas barrier, outer protective PE layer. USP <87>/<88> Class VI certified, ISO 10993 compliant, with a controlled extractables profile. BPOG-aligned extractables data is available on request.
2D bags are flat (pillow-style), 50 mL to 50 L, optimised for mixing on rocking or orbital shakers — primarily media prep, buffer mixing and small-volume intermediate hold. 3D bags are cubic and freestanding, 50 L to 3,000 L, for large-volume storage, bulk transfer and chromatography feed in support frames or cage systems. Both use the same RENOLIT 9101 film and carry equivalent GMP certifications.
Standard delivery from EU stock: 2–4 business days to Germany and Austria; 3–5 business days to Switzerland (export documentation included). Express delivery available on request. Contact us with your location, volume and required delivery date — we confirm stock availability the same day.
Yes. 3D bags are cold-room compatible when filled and sealed — suitable for bulk drug substance hold at 2–8°C and freeze-thaw applications where the support frame is designed for temperature cycling. Contact us with your cold storage requirement for material compatibility confirmation.
For EMA ATMP submissions under Regulation (EC) No 1394/2007 and mAb/biologic dossiers under EMA guidelines, single-use container documentation typically includes: USP <88> Class VI certification, gamma irradiation certificate, extractables data, and BSE/TSE-free declaration. All of these are available from SeamlessBio as standard with each lot.
