MDO process

Principle of operation

The MDO film orientation process is divided into four phases: heating, stretching, annealing and cooling. Depending on the application, the MDO is based on an 8, 10 or 12 roller concept.

1. Heating phase (2 or 4 rollers)
The film is conveyed on heated rollers to obtain the required temperature.

2. Stretching phase (2 rollers)
The heated film is stretched between two rollers to obtain the required stretching ratio.

3. Annealing phase (2 or 4 rollers)
Annealing rolls reduce the stresses created during the orientation process.

4. Cooling phase (2 or 4 rollers)
The film cools down and compensates for thermal shrinkage.
