Sealing technology

Hermetic sealing of plastic packaging can be achieved in a number of ways. CARAtec can help in an advisory capacity with two of these process areas. Thermal sealing of plastic containers (cups, bottles, ...) with films made from a wide range of different materials and the combination of sealing films with screw closures or slip lids.

  • Analysis of incidents, failures and faults relating to sealing problems on filling lines.
  • Analysis of incidents, failures and faults relating to the fitting of slip lids on filling lines.
  • Analysis and review of new sealing concepts (sealing film, slip lids) with regard to technical (mechanical, microbiological, sensory) workability on filling lines.
  • Support for the development of mechanical test methods for new sealing lid developments.
  • Monitoring of technical implementation of sealing solutions and their first field tests on filling lines.
