How to produce BOPP jumbo rolls?
- Unwinding.Put the BOPP Film on the unwinder of BOPP Tape Coating Line. There have two type unwinder, such as, Lifting and duplex
- Corona treatment on BOPP Film. Normally the BOPP film will be corona treated from the film making factory, so that we can get good coating effects due to the rough surface of film. But if the bopp film have not used for long time, the surface will becoming smooth and slip, it’s hard to tack with adhesives. Then, we should consider about the second time corona treatment
- Coating. There have two kinds of coating method, one is comma blade, another is mayer bar. Both coating method is good for operation, comparatively, mayer bar coating method will be a little easy for operation. But it depend on client’s operation habit.
- Drying. After coating, the coated film will enter the drying process. Then,vapor the residual water so that make the glue to be curing. Inside the drying oven, we adopt hot air circulation technology, blowing heating air and ventilate the wasted air with water.
- Cooling. Cooling is a very important process. When the film come out from the oven, the film molecule structure is on the expansion status, must make the film return the normal status by cooling process, so that the jumbo roll can get smooth appearance.
