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:
