Break closures

Break seals are proven safety elements for bag systems in medical technology and the pharmaceutical industry.

They ensure a sterile, tamper-proof connection and enable controlled opening immediately before use. By deliberately breaking an integrated predetermined breaking point, the flow is released without the need for additional tools or external opening steps.

Our breakable closures are characterized by high process reliability, reproducible breaking forces, and user-friendly handling. They are designed for different bag systems and connection geometries and can be reliably integrated into existing filling and sealing processes.

The materials used meet the high requirements for biocompatibility, sterilizability, and regulatory compliance.

Thanks to their precise design and robust construction, breakable closures contribute significantly to the product safety, user-friendliness, and quality of medical bag systems.

More information about break closure caps

We produce more than 80 million snap closures (assembled and unassembled) annually.

The Luer connector is made of polycarbonate. The caps are available in different materials and colors, such as POM or TBE.

We can look back on more than 30 years of experience in the production and assembly of break-off caps.

Process

Our Approach

1. Consultation

We record your requirements in detail and recommend the right solution for your individual area of application.

2. Design

Together, we develop the optimal geometry and precisely define the breaking force – for safe and clean application.

3. Production

We manufacture for our customers in a clean room using validated processes and test every batch – for consistent quality and reproducible results.

4. Delivery

We deliver on time and with traceability; at the customer's request, with proof of sterilization and a complete batch certificate.

Common problems

1. Imprecise break points: Unreliable breaking forces or uneven predetermined break points lead to uncontrolled opening and possible contamination.

2. Material incompatibility: Incorrect plastic selection can lead to stress cracks or leaks.

3. Lack of documentation and traceability: Without clear batch certificates and process documentation, uncertainties arise in quality assurance. And problems during or after production.

Our solutions

1. Defined break geometry: Each break-off closure is designed to open with a precisely defined force – reproducible and safe.

2. Material expertise: We select tested, biocompatible materials that are mechanically stable and chemically resistant—ideal for medical bag applications.

3. Comprehensive quality assurance: Each batch is documented, tested, and delivered in a traceable manner—with proof of sterilization and a certificate upon request.

FAQ

Frequently asked questions

What is the advantage of break-off closures over conventional systems?
They enable controlled opening without tools and reduce the risk of contamination.
Can breaking forces be customized?
Yes, we develop customized variants with precisely defined breaking forces and geometries.
What materials are used?
Depending on the application, we use PP, PE, or COP—all tested in accordance with ISO 10993 and USP Class VI.
Are the break-off caps available in sterile form?
Yes, optionally sterile packaged and validated according to standard sterilization procedures (gamma or EtO).
How is quality assured?
Every closure is tested and documented. Our production facility is ISO 13485 certified and validated.
