HDPE film poor heat sealing
Sorun Belirtisi
The heat seal strength of HDPE bags is low or cannot be sealed.
Neden Analizi
The heat seal temperature/pressure/time do not match the HDPE melting point; film surface contamination or slip agent migration affects sealing.
Çözüm
①Optimize the three elements of heat sealing (temperature/pressure/time); ②clean the sealing blade; ③evaluate slip agent migration; ④laminate an easy-seal material on the inner layer if necessary.
Temel Çıkarım
For heat sealing, first adjust the three elements, then check the film surface condition.
