Is it bad for PE film blower if the extrusion temperature is too high?

Release date:2018-12-21 09:40 Source: Click:

Extrusion temperature is too high, the fluidity of melt resin is too high, the viscosity is too low, and it is easy to fluctuate; Extrusion temperature is adjusted; Extrusion temperature is too low, the amount of material is less; The air volume of cooling air ring is unstable and the film bubbles are not uniform; The cooling air ring is checked to ensure uniform air supply around it.


It is disturbed and influenced by strong external air flow. Prevent and reduce the interference of external airflow. Film blowing opportunities for fine printing are more complex, and PE film blowing opportunities for non-printed inner film bags are simpler. Both models should pay attention to the output and thickness uniformity. The first one is to determine the size of die lip according to the thickness of the film produced, which is usually matched with a rotating die.


The price of film blowers ranges from tens of thousands to millions, mainly depending on the use of your products, and how much film is needed. The wider the film, the higher the price. Different uses require different configurations, such as supermarket shopping bags, agricultural film, vegetable bags and so on.


Basically, they will ask you what you are mainly about, and then recommend you the right machine. Do not lift the film, unload the wind ring, put the level ruler on the film head, open the rotary film head, observe the scale of the horizontal ruler. If there is a significant change in the rotation machine head, or there are problems in itself, there is no obvious change in the problem to save the wind ring, the air output is not uniform. Or alcohol is a problem with the runner at the head of the film.
