Manufacturing Process



Raw materials are loaded, mixed and fed into heating extruders. The molten material come out from die and is cooled to be ready for biaxial-oriented stretching. Firstly, Machine direction stretching and then Transverse direction stretching. The film is formed during the stretching process and 5 layers including the core layer, 2 inner layers and 2 surface layers are stretched to create a dimensionally stable substrate. The whole process is monitored and computer controlled to ensure superior product quality.
