Film production line MDO

double

With over 25 years of experience in monoaxial stretching, we are the pioneers in MDO technology The one-of-a-kind TRIO technology “Trim Reduction for Inline Orientation” provides significant material savings in edge trimming Superior MDO film quality with outstanding processability, optimized flatness and no hanging edges thanks to our new vacuum technology Produce blocked and double flat film on Hosokawa Alpine blown film lines and benefit from maximum flexibility for your production. 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.
