Designed around closure performance

Container Closure Integrity

Define closure integrity checks in the complete container system.

Low Fragmentation

Specify fragmentation and coring acceptance criteria.

Controlled Penetrability

Define the needle and acceptable insertion force.

Reliable Self-Sealing

Specify access count and test resealing in the intended assembly.

Low Extractables

Evaluate the selected compound with your formulation.

Sterilization Compatibility

Confirm the method and cycle for the selected compound.

Performance and compliance are validated to the agreed material, container and sterilization system.
