At TAPPI 2007 conference in Athens, the breakthrough development of converting an extrusion coating grade from a conventional autoclave reactor to a tubular reactor process. The aim of the project was to secure long term supply to the extrusion coating market. In a time that autoclave reactors are under increasing economical and environmental pressure, it was decided to develop an extrusion coating grade using the more sustainable LDPE CTR~R Technology (Clean Tubular Reactor Technology). In the mean time the corresponding SABIC~R LDPE nExCoat 5 (code for the rest of this presentation is T-MFR5) has been introduced into the market and an extensive experimental design study on a Pilot Extrusion Coating Line has been performed to investigate the typical characteristics of this grade. This study clearly demonstrates the excellent exchangeability of T-MFR5 with the conventional autoclave grades as well as some clear added values such as processability and adhesion. This paper will outline the typical properties and added value of T-MFR5 in comparison to the conventional autoclave grades. Furthermore, the advantages of our new innovative technology with respect to sustainability will be described into more detail.
