Screw Closures with sealing element

Secure sealing of filled material is achieved by the use of sealing inserts suited to the specific application. The Remy & Geiser standard range includes 2mm thick sealing inserts of various materials. No adhesive is used for securing in the screw cap, the sealing insert is retained in the cap by means of a clamping edge. The use of foam based sealing inserts is recommended for 95% of common commercial applications in the pressure seals sector. PE foam with a density of 200kg/m³, 300kg/m³ or 400kg/m³ is used which offers high elasticity and marked resilience. The PE foam insert can be surface laminated to improve the barrier function or resistance. The following types of lamination are recommended:

  • PE: synthetic oils, creep-prone products, for increasing mechanical surface strength
  • PET: aggressive fill materials, solvent-containing fill materials
  • Saran: oxygen barrier
  • Aluminium/PET: oxygen and water vapour barrier, aggressive fill materials
  • Teflon: aggressive or acid-containing fill materials
Further types of sealing inserts are shown in the listing on the page Sealing elements. We shall be pleased to assist you in selecting the product most suitable for your specific application.
