Fleboflex Container Technology & Design

The Fleboflex container represents a significant advancement over traditional PVC IV bags. Understanding its material science and design features helps clinicians appreciate why it is the preferred choice for modern outpatient infusion settings.

The container is fabricated from a polypropylene multilayer film. Polypropylene is a highly compatible material used for the preparation of intravenous mixtures — including drugs that have shown incompatibility with other plastics such as PVC. The solution contacts only polypropylene throughout the entire fluid path, including the inner membranes of both the medication and outlet ports.

Key design features include: rounded upper and lower corners that prevent accidental punctures during handling; an integrated eyelet support for safe suspension during infusion; and a totally collapsible design that eliminates the need for air venting during administration. The bag is lightweight and fully transparent, allowing clear visual inspection of the solution at all times.

The Grifols port system features medication and outlet ports designed with rigid, long tubes to prevent perforation due to needle insertion. The internal membrane provides safe attachment of the infusion set. Importantly, no parts of the cover need to be removed or broken to access the outlet port — reducing contamination risk.

Each container is individually overwrapped in a polypropylene protective sleeve that maintains sterility and limits evaporative moisture loss. The overwrap is transparent for visual inspection and features a peelable opening system for clean, easy access.
