Temperature control and influencing factors of blown film in blown film machine

For those who frequently use blown film machines, it is believed that blown film machines are not unfamiliar at all. However, one question that blown film machine operators are puzzled about is what temperature range is most suitable for blown film control. In fact, the high or low temperature of blown film in blown film machines may directly or indirectly affect the quality of blown film. So, what range should be controlled?
In fact, there is no fixed temperature for blowing film on a blown film machine. The reason for this is actually quite simple, which is that the temperature used by the film blowing machine during film blowing is related to the following aspects:
1. Different raw materials result in different temperature requirements.
2. The impact of different temperatures in the blown film environment on the blown film temperature of the blown film machine.
First of all, let's briefly talk about the impact of different raw materials on the temperature used during the film blowing process of the film blowing machine?
Different raw materials mainly refer to the different formulas and properties of the blown film raw material particles in the blown film machine.
Different formulas refer to the fact that different types of plastic blown film particles have different temperature requirements, so it is necessary to comprehensively consider the temperature conditions of the raw materials used in the formula blown film.
Different particle properties refer to the distinction between high and low pressure particles. For example, low-pressure particles have higher requirements for blown film temperature than high-pressure particles. Taking the convenience bag blown film machine as an example, when blowing the film on the convenience bag, low-pressure particles are generally the main ones, and the heating temperature of the blown film machine is generally between 180 degrees Celsius and 230 degrees Celsius.
Secondly, the ambient temperature of the blown film machine also has different requirements for the temperature required for heating the blown film machine. For example, the temperature in regions such as Hebei, Henan, Shandong, Shanxi, and Shaanxi is lower than that in Inner Mongolia, Jilin, Liaoning, and Heilongjiang when using a blown film machine.

This is the difference in temperature required for blown film machines due to China's vast land and abundant resources, as well as the large latitude span between north and south.
