Heat Seal Strength of BOPP Films

An article by admin    No Comments

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 other phenomena.

BOPP cigarette film use hot-pressure sealing, that is, to heat seal at certain heat seal temperature, pressure and time. The heat seal testing is to determine the minimum separating force after heat sealing. Usually, it is widely applied in the cigarette industry that  Heat Seal Tester and  Tensile Tester together. The heat seal strength of cigarette is normally required to be above 2.0N/15mm. Now, with the development of cigarette packing machine, low temperature heat seal film becomes more popular, which requires the heat seal strength above 1.5N/15mm.
