Production 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. 
The film is formed during machine direction stretching and transverse direction stretching process and is stretched to create a dimensionally stable substrate.
The whole process is monitored and computer controlled to ensure superior product quality.
Lichang synthetic paper has two kinds of structure: 3 layers structure and 5 layers structure, which enables more possible features of film and comes to the co-innovation with customers.
