General description

Inter-Seal bonded caps eliminate expensive and time consuming hand assembly while preventing liner fallout. They are made by a bonding process that bonds PTFE/silicone into polypropylene closures without using adhesives. The bonding properly seats and secures the septa within the vial opening. This integrated one piece system withstands multiple injections, making it very cost effective.
Benefits include:
  • Significant bond strength
  • Withstands multiple injections
  • Resistant to coring
  • Excellent resealability
  • Broad chemical resistance
