Low interlayer peel strength of PET composite sheet
Problembeschreibung
PET/PE or PET/EVOH composite sheets delaminate during '2079851475616104458 or use.
Ursachenanalyse
Adhesive layer thickness is insufficient or improperly selected; melt temperatures of each layer do not match; lamination pressure is insufficient; shrinkage differences between layers are large.
Lösung
Optimize adhesive layer material and thickness; adjust the temperature of each layer to match viscosities; increase laminating roller pressure.
Wichtigste Erkenntnis
The interlayer bonding force of PET composite sheet depends on the adhesive layer and the process matching of each layer.
