FreePack® 500


Producing individually-wrapped processed cheese slices (IWS) using a continuously operating production method.

The Natec FreePack® 500 machine produces individually-wrapped processed cheese slices (IWS) using a continuously operating production method. Wrapping is performed without risk of recontamination using the hot-fill system. The PP foil used is environmentally friendly and recyclable. Exact sealing ensures the product to be securely wrapped and sealed. The individually-wrapped slices are easy to open. They are of exactly uniform weight and accurately stacked in piles which remain in exact position during transport from the FreePack® to the Flowpacker.


  • Plastic foil need reduced by 10% due to small & efficient welding seams
  • Unique cutting and stacking technique which arranges and coordinates individually-wrapped slices into exact piles
  • High operator comfort and trouble-free production thanks to the central control and surveillance system
