The Production Way about our machine:

Firstly, the temperature control of the extruder is generally between 250 ℃ and 280 ℃. The next step is cooling. The temperature of the strip is very high after it leaves the machine head, so it needs to enter the water for cooling immediately, because isotactic polypropylene is easy to generate the brew crystal structure in the case of rapid cooling, and the molecular structure of the brew crystal is loose. Easy to stretch orientation to obtain high-quality products. Then there is stretching, which aims to improve the longitudinal strength of the packaging belt and reduce the elongation. The stretching must be carried out in boiling water, typically using a single stretch. Finally, there is embossing. After stretching, the packaging belt passes through two embossed rollers and is embossed with patterns. Its function is to increase friction during use, without slipping, and to look beautiful and generous from the outside.
