Varipack know-how on packaging films

At Varipack, we use customized mono and composite materials for your packaging.
In a personal discussion with you we evaluate your requirements for your flexible packaging.
Among other things, the following factors are included in the evaluation for your packaging:

  • Machinability (COF)
  • Sealing properties
  • Barrier properties (WDD, OTR)
  • Product resistance
  • Thermal stability (TK, RT, pasteurisation, sterilization)
  • Mechanical properties (drop test)
  • Organoleptic properties
  • Thickness reduction

We use the following, non-exhaustive, list of materials for our customers:
