Pharmaceutical Bulk Bags

Pharmaceutical-grade FIBCs (Flexible Intermediate Bulk Containers) provide a safe, traceable, and contamination-controlled way to store and move pharmaceutical raw materials, intermediates, and powders.  FlexSack’s pharmaceutical bulk bags are designed and manufactured to meet strict cleanliness, as well as barrier and handline requirements used across pharmaceutical supply chains.  

What Pharmaceutical Products are Shipped in FIBCs 

Pharmaceutical customers use FIBCs to transport and store a wide range of materials, including: 

Active Pharmaceutical Ingredients (APIs) 

Raw powders and intermediates 

Excipients & Fillers 

Lactose, microcrystalline cellulose, starches 

Pigments/Colorants 

Used in oral dosage forms and coatings 

Powdered Intermediates & Granules 

Spray-dried powders, pelletized intermediates 

Resins & Slurries 

Used in controlled-release coatings 

Seed Batches/Tablets-in-process 

And other nonsterile intermediates 

If you ship specialty chemistries or unusual formats, we’ll design the FIBC and liner system to match handling, cleanliness, and compatibility needs.

Why Use FIBCs for Pharmaceutical Products 

  • Regulatory & Material Traceability: FIBCs are produced to documented material specs so you can include packaging information in your submission files.  ISO standards apply to FIBC construction and testing.  
  • Container-Closure Expectations: Drug and biologic packaging materials often require documentation and compatibility testing as part of regulatory filings; packaging systems (including liners and closures) should be selected with those submission needs in mind.  
  • Contamination Control: Liners and clean manufacturing minimize foreign particulates and cross-contamination risk, which is critical for APIs and sensitive powders. 
  • Single-Use/Closed-System Benefits: Single-use liners and sealed FIBC systems reduce cleaning validation burden and lower cross-contamination risk vs. reusable containers.  
  • Static Protection & Powder Safety: For electrostatically active or flammable powders, anti-static/conductive FIBCs and appropriate grounding protocols reduce ignition risk during filling/discharge. 

Common Bag Types for Pharmaceutical Materials

Bag Type 

Ideal For 

Key Benefits 

Liner-Integrated FIBCs 

APIs, Hygroscopic powders, moisture-sensitive excipients 

Total barrier against moisture/contaminants; simplifies clean handling, pair with sterile liners for aseptic transfers 

Spout-Top/Spout-Bottom Bags 

Precise powder dosing, slurries, formulation batches 

Controlled fill & discharge with reduced dust and product loss; easy to interface to processing equipment 

Duffle/Open-Top (with inner liner) 

Large batch transfers, non-sterile intermediates 

Fast loading when sterility is not required; inner liner provides contamination control 

Aseptic/Sterile Single-use Systems 

Sterile intermediates or direct-to-process transfers 

Pre-sterilized liners and sealed closures minimize contamination risk and cleaning validation needs 

Anti-Static/Conductive FIBCs (Type C/D) 

Flammable powders, conductive additives, electrostatic-sensitive materials 

Built to dissipate or safely ground static charge; required where ignition risk exists 

Custom Solutions for Pharmaceutical Needs 

FlexSack manufactures pharmaceutical-grade FIBCs to match regulatory, process, and cleanliness needs.  Options include virgin-polypropylene construction in a cleanroom environment; single-use, pre-sterilized liners; metallized or co-extruded barrier films for oxygen/moisture control; anti-static/conductive fabric blends for electrostatic mitigation; and specially designed spout/slide-gate closures for closed-transfer systems.

What Our Customers Say 

“Let FlexSack come in and work with you to do what (our rep) did for me.  He wanted to see the specifications of the products to ensure that we can fill them to the correct cubic feet and dimensions.  He asked questions about how they’re being used, loaded, and filled.  He even came out and worked with my guys who filled the sacks and asked them questions…no one’s ever done that.   “

FAQ

Pharma-grade FIBCs are manufactured to cleaner processes (often in controlled environments), use virgin raw materials and food/pharma-compatible films, and are paired with liners and documentation to reduce contamination risk and support regulatory filings.  

Yes. Single-use, pre-sterilized liners and sealed packaging systems are available to support aseptic transfers and reduce cleaning/validation burdens. 

If your powder is flammable, generates dust clouds, or is prone to charge buildup during filling/discharge, anti-static (Type C/D) or conductive options and grounding protocols are strongly recommended to mitigate ignition risk. 

Typical deliverables include raw material specs (virgin resin), liner material certificates, manufacturing lot traceability, cleaning/sterilization records (if applicable), and test certificates showing conformance to relevant FIBC standards. (ISO 21898 provides design and test guidance for FIBCs).

Properly specified packaging, with documented materials, barrier performance, and compatibility data, can be included in container/closure and supply chain documentation required by regulators during submissions and audits. Consult your regulatory lead for the exact dossier language.
