Recyclable Barrier Systems for Sustainable Packaging

IKV develops recyclable packaging solutions with the help of plasma technologies and presents the current state of research at the IKV colloquium in September.

The Institute for Plastics Processing at RWTH Aachen University (IKV) develops recyclable packaging solutions with the help of plasma technologies and presents the current state of research at the IKV colloquium in September.

Complex multi-layer composites consisting of different plastics that in each case fulfil a necessary packaging function are currently still heavily represented in packaging technology. At the end of their useful life, these composites can be used only for energy recovery because they cannot be segregated into their various constituents. With the help of the Plasma Enhanced Chemical Vapour Deposition (PECVD) technology, plastics can be provided with a high-quality gas barrier that does not impair the recyclability of the plastic. In the discussions on the circular economy, the plasma technology has developed into a highly dynamic area of research with a broad relevance and key innovative force.

The market for flexible packaging is facing major changes because of the challenges that will come about in the transition to the plastic circular economy. Although plastic film is now already being successfully provided with a barrier coat in discontinuous „roll-to-roll“ coating processes, there is at present still no continuous process variant that eliminates the non-productive times that are unavoidable in present batch processes and hinder the overall aim of improving the economic efficiency of the process.

The target is therefore to overcome this problem with the help of an innovative machine development for continuous PECVD film coating. Here, the film is unwound under ambient pressure and passed through a sluice system into a vacuum chamber, in which a SiOx coating is efficiently applied through a so-called „in-plasma concept“. Subsequently, the film is again passed through a sluice system at ambient pressure and wound up. Using conventional joining procedures, the process can be carried out without any interruptions. To develop the complex sluice and vacuum systems, the required pump performance is currently being evaluated and a sealing concept is being devised

Coating of Large-Volume Blow-Molded Parts

The potential and innovative strength of the plasma technology for the circular economy is shown in the founding of the <a href="https://www.kunststoffe.de/a/news/start-up-will-beschichtete-kunststoffver-327962" target="_blank">deep tech startup, IonKraft, which has its roots in the </a>Institute for Plastics Processing. IonKraft transfers scientific findings from plasma research to industrial production technology. Based on research and development work carried out in the 1980s at IKV, which has now led to marketable products in the form of interior coatings for PET bottles, IonKraft is focused primarily on developing a systems technology for the coating of large-volume blow-molded parts. After all, this type of packaging, which is frequently used, for example, in agricultural technology, also needs – for various reasons – to have barrier properties.

Before now, this was only possible with multi-material systems that are unsuitable for recycling. The scaling-up of the process to larger volumes certainly makes fresh demands on the coating machine technology, which have to be met through new constructive modifications in the vacuum technology and also in the microwave technology. Furthermore, the sometimes aggressive agricultural products also make new demands on the PECVD barrier coat, which must also have media-specific resistance properties for this. The business project is being funded by the EXIST research transfer program of the Federal Ministry for Economic Affairs and Energy.

Use of Post-Consumer Polypropylene for Food-Contact Applications

The reuse of high-grade recycled plastics in packaging that comes into contact with foodstuffs is – with the exception of PET – not yet properly established. One of the main reasons for this is the authorization regulations of the European Food Safety Authority (EFSA), which makes strict requirements on the permitted migration of foreign substances from the packaging into the food. Plasma technology is also an obvious candidate for solving this problem: The good barrier properties that are known to exist against water vapor, oxygen and carbon dioxide should also provide very good resistance to the residual foreign substances from recyclate material.

The development and testing are being carried out on standard post-consumer recyclate (PCR) from the DSD (Duales System Deutschland). In the first step, the contamination of the recyclate and its absorption by foodstuffs is simulated with the aid of test substances. In a second step, suitable coating systems are developed that may have to be coordinated to the specific substances. These coating systems are subsequently tested for their suitability for reducing migration. The research work is being supported by the partners Gizeh Verpackungen GmbH & Co. KG and the Green Dot – Duales System Deutschland GmbH. The University of Paderborn is also providing assistance with its expertise in analytics. The approach being pursued can be applied to both rigid and flexible packaging.

The research project described here offers enormous potential for achieving the targets of the European Commission, namely to recycle 55 % of plastic waste by 2030, and thereby substantially increase the proportion of recyclate material used in plastic products.
