With the concept of green energy conservation becoming more and more popular, many mechanical products with high consumption and low efficiency are gradually eliminated in the market. The plastic film blowing machine industry keeps pace with the times and moves forward towards energy conservation and emission reduction. Under the situation of advocating energy conservation and emission reduction all over the world, all walks of life are working together. Under such a good situation, the film blowing machine is also actively transformed to save energy.

With the rapid development of modern food industry, plastic flexible packaging has become the main form of food packaging. When flexible packaging gradually becomes the protagonist of food packaging materials, film blowing machine is naturally one of the most important mechanical equipment in the industry. With the concept of green energy conservation becoming more and more popular, many mechanical products with high consumption and low efficiency are gradually eliminated in the market. The plastic film blowing machine industry keeps pace with the times and moves forward towards energy conservation and emission reduction.

When it comes to the energy-saving transformation of PE film blowing machine, it mainly starts from the power part and heating part. In the power part, frequency converters are mostly used. The energy-saving method is to save the residual energy consumption of the motor. For example, the actual power of the motor is 50Hz, but you actually only need 30Hz for production. Those excess energy consumption will be wasted. The frequency converter is to change the power output of the motor to achieve the effect of energy saving; The heating part mostly adopts electromagnetic heater to save energy, and the energy-saving rate is about 30% - 70% of the old resistance coil. The reformed film blowing machine has the following energy-saving advantages:

1. Compared with resistance heating, the heating speed of electromagnetic heater is more than one quarter faster, so the heating time is reduced.

2. Compared with resistance heating, the heating speed of electromagnetic heater is fast, the production efficiency is greatly improved, and the motor is in a saturated state, which reduces the power loss caused by high power and low demand.

3. Compared with resistance heating, the electromagnetic heater has one more insulation layer, so the utilization rate of heat energy increases.

4. Compared with resistance heating, the electromagnetic heater directly acts on the material pipe heating, thus reducing the heat loss of heat transfer.

At present, the popular packaging in the market is mainly plastic and paper, and the plastic blowing industry dominated by plastic film blowing machine accounts for a large proportion in the market. However, with the increasingly strict requirements for the paper industry, the new indicators of environmental protection and energy saving have raised the threshold of the paper industry, resulting in the expansion of the cost of the paper packaging market and the rise of prices. This makes the share of plastic packaging in the market increase accordingly, and stimulates the development of film blowing machine manufacturing machinery industry.
