to produce a packaging film. The impregnated mineral is hydroscopic and has permeability characteristics. When used with refrigeration at the correct temperatures levels, PEAKfresh
will extend the life of your product.


  • Excellent permeability to gases

  • Good food deodorizing properties

  • Removes ethylene gas

  • Anti-fog treatment to reduce water formation
