Runs on reliable PLC platform

Modular design

Designed with lifecycle costs in mind


The RS Series Thermoformer is an amazing step to a more efficient vacuum packaging line. The machine makes its own deep-drawn packages from rolls of film. Your products are placed in, then the RS thermoformer quickly seals them under vacuum or modified atmosphere.

The Advantages of Thermoform Packaging are:

  • Longer Shelf Life
  • More control over package sizes and shapes
  • Increased number of products can be run on a single rs Thermoformer with unlimited die configurations
  • Lower packaging cost with film used as basic material
  • Reduced operating cost with few employees needed to operate
  • Minimal material storage cost, because packages in various shapes can be made off the same film rolls
  • Packages can easily be used for industrial or retail/consumer purposes
  • Maximum packaging performance
