Main causes and solutions for poor film sealing of film blowing machines
2025-02-13When film blowing machines heat seal, the heat sealing temperature or heat sealing knife clamp sealing pressure and cooling conditions must be considered. Because most common problems of poor sealing are caused by this, the following six points are summarized, hoping to be helpful to you.
Common problems of film blowing machines
Q1: Severe uneven film thickness or incorrect thickness
A1: Please blow the film strictly in accordance with the correct blowing ratio setting range.
Q2: The sealing temperature is too high
A2: Reduce the sealing temperature.
Q3: The sealing pressure is too low or too high
A3: Adjust the appropriate sealing pressure or use a high-efficiency heat sealing knife.
Q4: The sealing temperature is not enough or the sealing residence time is not enough
A4: Increase the sealing temperature and sealing residence time.
Q5: Problems with the film raw material formula
A5: Review the original film raw material formula to see if there is any improper mixing.
Q6: Excessive electrostatic treatment
A6: Reduce the degree of electrostatic treatment.
