Heat seal strength is one of significance properties  for  BOPP Cigarette film quality control. BOPP films require high heat seal strength and wider heat seal scope by the cigarette industry, so as to improve packing speed and proper operation. However, if the heat seal temperature is higher, it would lead to wrinkle because of increased BOPP film shrinkage. Therefore, proper heat seal temperature should be chosen so as to avoid unstable heat seal, wrinkle and [...]
