Insufficient strength of PVA water-soluble film
Fenómeno do problema
PVA water-soluble film tensile strength <30MPa, below the 40MPa requirement
Análise das causas
PVA alcoholysis degree on the low side causing insufficient strength; film thickness insufficient
Solução
1) Select high alcoholysis degree PVA >98% to increase strength; 2) Increase film thickness; 3) Add 5wt% plasticizer to improve strength
Conclusão principal
PVA water-soluble film strength is determined by alcoholysis degree; selecting a high alcoholysis degree grade is the key
