Temperature Control And Influencing Factors Of Blown Film in A Film Blowing Machine

For those who frequently use film blowers, I believe they are not unfamiliar with them at all. However, there is one question that the operator of a film blower is puzzled by: what temperature range is the most suitable for controlling the blown film of a film blower? In fact, the high or low temperature of the blown film of a film blower may directly or indirectly affect the quality of the blown film. So, what should be controlled within?

In fact, there is no fixed temperature at which a film blowing machine can blow the film. The reason behind this is actually quite simple, which is that the temperature used by the film blowing machine is related to the following aspects:

1. Different raw materials result in different temperature requirements.

2. The impact of different temperatures in the blowing environment on the blowing temperature of the film machine.

Firstly, let's briefly talk about the impact of different raw materials on the temperature used during the 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 film blowing machine.

Different formulas refer to the fact that different models of plastic blown film particles have different temperature requirements, so it is necessary to comprehensively consider the temperature of the raw materials used in the blown film formula.

Different particle properties refer to the distinction between high and low pressure particles. For example, low pressure particles have higher requirements for blowing film temperature than high pressure particles. Taking the convenience bag blowing machine as an example, when blowing convenience bags, low-pressure particles are generally the main material, and the heating temperature of the blowing machine is generally between 180 ° C and 230 ° C.

Secondly, the ambient temperature of the film blowing machine also has different requirements for the temperature required for heating the 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.

This is the difference in temperature required for film blowing machines in China due to its vast territory and abundant resources, as well as the large span of latitude between north and south.
