At Datwyler, we offer our customers the most advanced applications to protect the integrity of these crucial systems while ensuring a convenient handling.

Reliable integrity paired with flawless handling.
Plungers are a critical component of any prefilled syringe, because they must demonstrate both perfect Plunger Barrel Seal Integrity (PBSI) and flawless gliding behavior. This ensures that syringe contents are administered safely and consistently to patients even after several years of storage.
At Datwyler, we are aware of these requirements. As experts in material science, we have developed one of the cleanest proprietary elastomeric compounds used in plunger manufacturing. With the highest-quality materials and coating technologies, we supply our customers with safe and effective sealing solutions.
Protecting the needle from external forces is another important aspect when it comes to injectables. With our line of needle shields and tip caps, we offer our customers high-end closures while guaranteeing safe and effective processing during production and handling. Both our soft and rigid needle shield are high-quality protective solutions that ensure the needle is not damaged during manufacturing, filling, and distribution.
Advanced formulations for advanced applications.
As experts in material science, Datwyler has developed the most innovative, clean elastomeric compounds used in plunger manufacturing. Developing proprietary compounds, such as FM257 and FM457, has allowed Datwyler to grow its product portfolio to meet a wide range of customer needs.
With its fluoropolymer spray coating technology, Datwyler contributes to a reduction in overall particles. The proprietary coating provides a protective barrier to external contaminants, prohibiting leachables from entering the product and ensuring a contact-safe surface that is compatible with the drug.
Datwyler's coated prefilled syringe plungers are part of the NeoFlex™ plunger platform, with sizes ranging from 0.5ml to 3ml. Compatible with all types of prefilled syringes, Datwyler’s vast selection of plungers guarantees its customers the ideal type for their drug product needs.

Patient's safety first. Individual closures for prefilled syringes.

Needle shields protect prefilled syringes safely and effectively.
At Datwyler, we use our material knowledge to develop individual closures specifically designed for prefilled syringe solutions. Using elastomeric compounds, our range of needle shields provides a sterile barrier to ensure maximum container closure integrity while also protecting the needle from external forces.
Our needle shields are designed to provide a safe and effective experience during manufacturing and handling of prefilled syringes. We offer soft and rigid needle shields that protect pre-attached needles from damage during manufacturing, filling, and distribution.
All of our needle shields are compatible with all types of prefilled syringes and comply with ethylene oxide (EtO) sterilization. They are also available in ready-for-sterilization (RFS) packaging.
Datwyler’s rigid needle shields. Best-in-class offering.
Datwyler’s premium needle shield compound, FM30, is the preferred solution for prefilled syringe customers. Our FM30 rigid needle shields are available in 1/2 inch and provide the necessary protection to both the needle during manufacturing and the end-user during handling.
Rigid needle shields help reduce needle stick injuries during handling in the field. Datwyler’s rigid needle shield is a high-quality protective solution that ensures an easier and more intuitive removal while preserving the needle.
