Surface Treatment at Extrusion

Welcome to the 2nd issue of ‘Surface Treatment Insights’ – a unique opportunity to understand the science behind the technology and how it can improve the efficiency of your production process.

This time, we look closer at ‘Extrusion’ – and the key part that correct surface treatment plays in preparing plastic film for the various processing stages it will undergo before becoming flexible packaging.

Download our Tech Paper or watch our Webinar on Demand and find out why surface treatment at extrusion is so important.

KEY POINTS

If you thought that surface treatment was straightforward – think again!

Understanding the extrusion process and the effect it has on the production chain of printing and converting film is an essential key to success – and it’s all about dyne levels.

Here are our five key points to remember:

Different films have different 'natural' dyne levels
Different dyne levels allow different processes to be carried out
Dyne levels decay over time at different rates on different films
Solvent-based inks require different dyne levels to water-based inks
Cast film extruders require higher power corona treaters than blown film extruders because they operate at higher speeds

If you understand the extrusion process - you are halfway to getting production right!
