Description
In small-volume biopharmaceutical processes—such as API sampling, cell harvest aliquoting, and buffer preparation—traditional storage bags often fail to address two critical pain points: leak risks (due to weak seals) and residual liquid waste (from poor design). Single-welded bags may seep during transfer, while rigid containers are bulky for small volumes and hard to empty completely—leading to costly loss of high-value small-batch materials and non-compliance with GMP standards.
Our Small-Capacity 2D Pharmaceutical Storage Bags are engineered to solve these issues, tailored for small-volume (50mL-50L) storage and transfer of APIs, pharmaceutical liquids, and cell harvests. The core protection lies in double-welded seal technology: both the bag body seams and port connections are welded twice via precision heat-sealing, forming a gap-free seal that undergoes 100% leak testing (pressure hold + vacuum decay) to eliminate seepage—even for low-volume, high-viscosity liquids.
Crafted from multi-layer co-extruded biopharmaceutical film (By Renolit 9101 film), the bags offer excellent chemical compatibility (safe for acidic/alkaline APIs and cell harvests) and low gas permeability—preserving the stability of sensitive liquids. The specialized wedge-shaped design uses physics to guide liquid aggregation for thorough emptying, while boat-type connectors prevent residual liquid buildup at the bag mouth—reducing residual volume to ≤0.5% of total capacity, minimizing waste of small-batch materials.
Manufactured in a Class C+A clean room, the bags are gamma-sterilized, ready for immediate use in sterile processes. High transparency of the bag body enables visual inspection of liquid clarity, supporting auxiliary process judgment. Whether for small-batch API storage, cell harvest sampling, or buffer preparation, these double-welded 2D bags deliver reliable leak protection, efficient liquid emptying, and regulatory compliance for small-volume pharmaceutical workflows.
