MDO* is a proven technology which saves resources, improves film properties, and optimizes films for specific uses.

With MDO from W&H, both cast and blown film can be stretched monoaxially on- or offline. The process improves barrier properties and gives mono and coextruded films enhanced tensile strength
and stiffness, better shrink properties, and increased gloss and transparency.

The improved performance of MDO films translates into significant savings with reduced use of expensive raw materials, especially
for barrier films.  At the end of the day, less material is used, which
is good for both the environment and your bottom line.

MDO-optimized films can be used for a wide range applications, including barrier films,  breathable films for hygiene and construction, as well as films for heavy duty sacks, adhesive
tapes, labels, stand up pouches, and food packaging. Additional applications are under development.

The MDO complements W&H's blown and cast film equipment,
but can be used for films from other sources. Cost-effective inline MDO is recommended for extruded films (from cast or blown film lines with slitting and unfolding). The offline system is a stand alone machine independent from the upstream film extrusion process.
It consists of unwinding, stretching and rewinding using winders from W&H's FILMATIC range. A great advantage of offline MDO is
the versatility offered which allows an extensive range of films to be processed.

Both the in- and offline versions offer a wide range of selectable variations include heating, stretching gap, conditioning and cooling rolls, which enable thickness, stretch ratio and other film properties to be optimized.
