Versiv products of choice
PTFE Cast Films such as DF1700, DF1100 and DF3100 are valued materials in the pharma space.
The multilayer construction of these films has isotropic properties and uniform tensile strength, reducing the risk of pinholes or contamination. They are uniquely bondable to several sealing substrates such as butyl rubber and other elastomers.
Versiv PTFE Cast Films used in medical applications are rigorously tested by customers to meet stringent standards — keeping impurity levels below 1 ppm and safeguarding patient safety.

Conclusion
Pharmaceutical rubber stoppers contribute to medical drug packaging by preventing cross-contamination and maintaining product integrity. Through innovative materials and design, these closures support safer, more efficient lab and pharma operations, safeguarding both patient safety and product quality.
The use of PTFE-based materials means closures withstand repeated use, sterilisation and freeze-drying cycles without sticking or degrading. The properties of the materials deliver conformability and surface bonding that reduce the possibility of closure failures, reducing recalls and product waste. There is an additional benefit as low-friction, high-purity materials reduce wear on automated equipment, translating to fewer breakdowns and lower total cost of ownership.
