During film blowing, film width and thickness fluctuation caused by film bubble instability, spiral instability, serpentine shape, film bubble sagging, etc
The unstable factors of degradable film bubbles produced by degradable film blowing machine are as follows:
1. It is closely related to the extrusion temperature of raw materials and the air flow during film blowing.
2. Also affected by the extruder temperature, the temperature is low and the film blowing discharge is low.
3. The most critical and non negligible point is the melt strength and melt index, which are numerically in the opposite direction. It is easy that the higher the strength, the lower the melt index.
4. The solution pressure is too high, which will cause the risk of material leakage. The set film blowing machine temperature can be increased to increase the fluidity of the solution. A wide die gap can be used to reduce the die head pressure.
