During film processing, the EVOH layer is positioned as the middle layer, and PP, which has excellent high water barrier properties, is made of the outer layer in a typical three-layer film.
For the multi-layer foil (PET/EVOH/PP) the water vapor permeability value is situated at an average level due to the EVOH layer.
The process is based on the coinjection used by Kortec to mould PET bottle preforms and injects the EVOH barrier layer into the cap in a single cycle, with no time penalty over mono-layer injection.
Humidity--At high humidity levels, the barrier provided by EVOH drops rapidly.
The EVOH copolymer is used as a wrapping material for foods, among other applications.
