Interview with Dr. Daniele Borin (Taghleef Industries) about BOPP barrier films

Karsten Schröder spricht in Berlin mit Dr. Daniele Borin, Produktmanager für Flexibles bei Taghleef, über PP-basierte Folienverpackungslösungen.

Daniele stellte vor, wie BOPP-Folien sowohl als Druck- als auch als Barrierefolien verwendet werden können. Das EXTENDO®-Portfolio erfüllt die anspruchsvollsten Anforderungen in Bezug auf Wasserdampf-, Aroma-, Sauerstoff- und Mineralölbarriere.

Entdecken Sie, warum dieser Ansatz mit PP-basierten Barrierefolien die Kreislaufwirtschaft unterstützt und Lebensmittel richtig schützt

Transkript

I’m here with Daniele from Taghleef and he was talking in his presentation the brilliant one to be honest about OPP and mono material layers. Why do you think OPP is one of the main materials for monomaterial solutions for flexible packaging? Yeah. Thank you very much Karsten for the appreciation of my presentation.

Let’s say polypropylene by actually in the polypropylene is a material that traditionally is used on packaging machines taking all the advantages that polypropylene can brings we decided to integrate further functionalities on polypropylene. So incorporating barrier incorporating sealing performance and incorporating heat resistance, so to get the monomaterial solution based on polypropylene from Taghleef or Flexpack. I don’t know exactly I learned that polypropylene has a good water vapor transmission barrier.

Yeah, but not so good against aroma and oxygen but you’ll solve this problem how yeah incorporating barrier so incorporating specific polymers and specific barriers that allows to implement and complete the properties of quality property land.

Providing also oxygen barrier battery terminal alloys and battery to aroma that sounds to me that these barrier good barrier properties against aroma and of course so oxygen seems to be the key to be used more in the flexible packaging industry because OPP normally is only used for water vapor transmission, but you know, it’s open doors. Yeah for sure when you want to move to monomaterial you need in any case to provide functional properties and good product protection.

So of course incorporating barrier is essential to keep the food protection and so to keep the shelf life of the product and avoiding food waste and of course the supply chain changes a bit. If you bring the barrier into your OPP film and the converter buy the ready-made barrier film from you, he does not buy polyethylene film for instance for the sealing layer with barrier. So is this an impact you you focusing on or is it? Not very important for the converting industry. It’s a change I guess. Yeah.

Our aim is to provide a one-stop shop. Let’s say so in our development in our portfolio. We are integrating the barrier but we are also improving the sealing performances. So our final target is to deliver a monomaterial solution that not necessarily needs polyethylene as a solution for the sealing web. And if you are talking about OPP or polypropylene monomaterial, is it the sealing layer also polypropylene or could it be polyethylene as well?

And this is that also a mono material solution, our main choice, our main proposal when we realize that barrier in the polypropylene is not enough for sealability, we suggest to use gas barrier polypropylene. And so if not yet enough for the application, we could also consider polyethylene. But of course we are not entering anymore in that target of monomaterial, what is still an all living based solution. There’s no impact on recyclability concerning the barrier structure of your external film.

Our extended film art design to be in line with guidelines about the recyclability, so that sounds great. Yeah, so you can’t make an OPP film out of it, but you can make OPP regrinds to recycle the polypropylene for other applications, right? Yeah. Yeah, exactly. And you’re one of the leaders of OPP films. Is this only a niche product or is the external product of something you you will sell all over the world target.

Wachstum durch Circular-Economy-Anforderungen

We are experiencing more and more in the growth of extended because of circular economy requirement, the requirement of mono material and so recyclability. Yeah, so we are experiencing a very big demand on this film and this is also confirms the quality of the film and our value proposition. So do you think it’s a worldwide trend to mono materials, just a European thing? No. No, it’s going worldwide, right? Yeah. Thanks for this explanation. Thank you very much. Thank you, Karsten. It’s been a pleasure.
