Steel coil packing machine
How to pack the steel coil
What is a fpc1? Pre-stretching is the process of stretching the membrane before it is applied to the load. Two wheel is through the film, is the primary and secondary roller and the second roller, the second round of rotation speed compared with the first rotation speed, the second round of rotation speed significantly faster, so stretch film between two rollers is drawn. When you stretch the film, it increases the tensile strength of the film, and once the permanently deformed point is exceeded, the result is that it becomes stronger. Returning it to its original form is what film memory wants to do. However, the lower you are, the lower your memory will be. That's the reason for not having a job in two periods of time. If the movie is applied to a load that doesn't have a film force, then a few minutes later, the movie has been tightened and you'll see it, because the coil wrapping film's elastic memory is being tried back. So that's the memory of the movie, for example, like the rubber band on your hand, to make a distinction between the stretching membrane and other combinations. In the process of transport of sediment, it also has other USES, to relax and other methods of the combination of relaxation time is occupied by a fpc4, and load can be continue to guarantee. The most important reason for PR stretching film is film memory!
