Schreiner MediPharm partners with Plas-Tech Engineering

Schreiner MediPharm launched the Cap-Lock cap adapter, the first opening indication for prefilled syringes, in the fall of 2019, followed less than a year later by a product evolution featuring a label-integrated inlay for automated supply chain management and digital first-opening indication. 

The development partnership between Schreiner MediPharm and Plas-Tech Engineering optimizes industrial manufacturing of the cap adapter to provide pharmaceutical manufacturers with a full-service technology for equipping their luer-lock syringes with reliable tamper evidence.

Cap-Lock is a security concept for prefilled syringes developed by Schreiner MediPharm combining a cap adapter and label. A syringe sealed with Cap-Lock irreversibly indicates if the syringe has been opened before. This ensures the integrity of the primary container and prevents its undetected opening. Unlike shrink-wrap technologies, Cap-Lock is also suitable for heat-sensitive substances.

Specializing in customized prefillable polymer syringes and injection-molded parts, Plas-Tech Engineering develops and produces the cap adapters. The cap is precisely adapted to the syringe and ensures accurate interlinking with the primary closure to equalize the diameter differences between the syringe body and closure. The cap adapter can be realized in a variety of colors to emphasize the desired branding. In addition, customization of the cap surface texture supports safety and ease of opening the syringe.
