We have invested in state-of-the-art laboratory equipment to evaluate advanced high performance multilayer films for you - our customers. The three layer co-extrusion blown film line was installed after monitoring market trends that are moving towards optically clear multilayer film architecture for applications such as food packaging.

These films may be blown or cast, but problems can occur in the production process as a result of different combinations of polymers and layers with different rheological characteristics. The films offer a range of benefits, such as improved barrier properties, adhesion, mechanical properties and cost reduction, but if the layers meet at the die at conflicting rates, the resulting ‘interfacial instability’ can disrupt the optical clarity of a film – a key criterion for some food packaging applications, for example, meat and poultry barrier films. 

3M Dynamar Polymer Processing Additives can provide a solution to these problems and improve the surface properties of multilayer films. In addition to these benefits, a resulting pressure reduction in the production process facilitates increased output and cost savings. 

Our technical experts can use the laboratory co-extrusion blown film line to study the performance of the Dynamar Polymer Processing Additives under different conditions. This will enable them to determine the appropriate concentration and method of application based on the customer’s formulation before moving to full-scale production. 

Our Advanced Materials Division is dedicated to responding to market and customer requirements. This investment will further enhance our technical leading role in this field and is a major benefit for our experts working in Research and Development and Sales. A video on this new machine will be introduced on the 3M booth no. B10 hall 5 at the K 2013.
