Development of new sustainable solutions for flexible packaging based on secondary stretching of blown polyolefin film with MDO technology

Awarded: NOK 5.9 mill.

One of the drivers for innovation in the packaging industry has always been the search for cost efficient solutions that balance the best achievable performance with the best cost position. In recent years environmental concerns have also become of major importance, as awareness has increased that energy efficient systems are crucial for reversing climate change. In the project we will develop sustainable solutions for flexible packaging by use of secondary Machine Direction Orientation, MDO of blown fil ms. By this method the film properties and balance of properties are significantly improved, and it is possible to produce films with reduced film thickness and retained or improved physical and mechanical properties The goal is to achieve film solutions with reduced material consumption, increased converting and packaging speed, simplified recipes and reduced number of process steps. The MDO technology has been known for several years, but for a limited number of applications, and with few materials i nvolved. There are several technical challenges that needs to be solved, for example with respect to sealing properties, barrier properties, shrinkage properties and other physical properties. The research program in the project will contain comprehensi ve trials where blown film will be extruded from various polyolefin materials. The films will be stretched or oriented in an MDO unit and physical and mechanical properties will be measured. The stretched films will be tested in converting equipment and p acking lines. Through this project the partners will increase their competence with respect to MDO technology, and it will make them able to develop and commercialize profitable and sustainable flexible packaging solutions.
