Insufficient EMA transparency

Fenómeno do problema

EMA film haze >20%, below the 5% transparent packaging requirement

Análise das causas

EMA methyl methacrylate content too low with crystalline region scattering; extrusion cooling rate too fast

Solução

1) High MMA content EMA with MMA>20% to lower crystallinity; 2) Lower cooling rate; 3) 0.3wt% nucleating agent for uniform crystallization

Conclusão principal

EMA transparency is affected by MMA content and crystallization scattering

EMA film transparency haze MMA content nucleating agent
