2D and 3D single-use bags
Flexible containers for closed fluid storage, hold, transfer and dispensing—from small process additions to production-scale batches.
Final film, port, line and connector compatibility must be confirmed for the actual fluid and operating conditions
Product formats
2D bags use a flat, pillow-style geometry that is easy to handle at small and medium volumes. 3D bags expand into a cubic or rectangular form inside a reusable support container, improving space use and handling as batch size increases. Both formats can be supplied as simple containers or as complete, gamma-ready assemblies with fluid lines and end connections already installed.
A compact format for small and medium process volumes, additions, sampling and development work.
Nominal portfolio 250 mL to 50 L
A cubic or rectangular format sized to a reusable support container for improved space use and production-scale handling.
Configurable portfolio 10 to 3,000 L
Film platform and assembly design
Available multilayer films use a polyethylene fluid-contact surface, an ethylene-vinyl-alcohol gas-barrier layer and a durable polyolefin exterior. Two film constructions are available at approximately 305–310 µm total thickness, allowing selection for process compatibility, clarity and handling requirements.
End-user applications
Select the format, working volume and fluid-path configuration around the process step, handling method and receiving equipment.
Preparation, storage and distribution of process solutions.
Feed, base, supplement and antifoam hold before addition.
Collection and transfer between downstream process steps.
Stock-solution, formulation and bulk-fluid containment.
Transfer between upstream, downstream and filling operations.
Additions, sampling and process-development activities.
Quotation preparation
A complete RFQ should identify every product-contact component, interface and packaging requirement for technical review.
Identify the solution, concentration, contact time, temperature and intended operation.
State working and maximum fill volume, orientation and the reusable container or handling method.
Define every inlet, outlet, drain, vent and sample line, including tubing material, size and length.
Select sterile, aseptic, weldable, luer, quick-coupling or sanitary interfaces for each line.
Confirm packaging, gamma dose range, leak-test requirement, labeling and documentation package.
Configuration matrix
Film, port, line and connector compatibility must be confirmed against the actual fluid and operating conditions. Nominal volume is not the same as recommended working volume.
