Poor printing adhesion of EEA film
문제 현상
EEA film ink adhesion
원인 분석
Poor affinity between EEA surface polarity and ink; corona treatment effect decays fast; ink system not matching EEA
해결 방법
1) Print immediately after corona treatment, within 24h; 2) Use EEA-specific ink; 3) Increase corona power to 15-20kW/m² to ensure surface tension >42mN/m; 4) Flame treatment to assist surface polarization
핵심 요약
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are the key
