Plastics of the Future: Sollex Insights from Plastteknik Nordic Fair 2023

Sollex visited the Plastteknik Nordic trade fair in Malmö on Wednesday the 10th of May 2023. In this article are our impressions from the leading Nordic plastic fair.


Plastic is a future material that cannot be replaced. It is an amazing material that, when produced and used wisely, has a positive effect on our daily lives. But plastic materials must be properly and effectively used and recycled. There are many problems and processes that need to be improved. But having been to the fair, we noticed an incredible leap in new climate-resistant technologies, materials and processes. 

After the curtain of restrictions caused by the Corona pandemic fell and trade fairs were held everywhere, the trend towards climate-resilient development in all fields of industry, especially the plastic industry, became especially evident. 

Bioplastic is a key material that was the talk of the fair and the developments of bioplastic materials were represented at almost every exhibitor at the fair. Plastteknik Nordic had three focus areas:

  • Sustainability and circular economy
  • The role of plastics in the public debate
  • Innovations and New Technologies

Focus on solving major life cycle issues and the different steps in the value chain such as raw materials, production, use and recycling was evident from all exhibitors and participants. They did not only focus on packaging, but also on the plastic flows from products, agriculture, demolition projects, etc. that do not have a functioning recycling system.

Below we will tell you about the particularly interesting participants of the Plastteknik Nordic fair from a Sollex perspective.Materialsmart - The right material in the right place reduces cost and CO2-e - Polykemi Group- Sollex Blog

Materialsmart - The right material in the right place reduces cost and CO2-e - Polykemi Group

Materialsmart ( is a project presented by The Polykemi Group, which consists of Polykemi, Rondo Plast and Scanfill subsidiaries. The aim of the "Materialsmart" project is to take a smart approach to material selection, i.e. to choose the most suitable material for each individual product or packaging. 

In many cases, plastic can replace metal, wood, fiber or paper and at the same time provide significant savings in terms of climate, cost and functionality. In the calculator on their website, you can easily simulate how the climate impact is reduced when switching to a more climate-smart material, i.e. a new plastic raw material, a recycled material or a combination of both. 

For example, changing the packaging material from PP to PP 100% PIR reduces the climate impact by 91% and the new packaging is 10.8 times more material smart; changing PET to PET 80% PCR reduces the climate impact by 47% and the packaging is almost twice as material smart. It says they use a Life Cycle Assessment (LCA ISO 14040) method to evaluate the environmental aspects of existing or planned products.

Here in our blog article Blades for Industrial Plastic Recycling Machines [Customer Case], we share our experience with a leading plastic recycling company, Rondo Plast AB.

Nordic Bioplastics Association Showcases Sustainable Innovations at Plastteknik Nordic Fair

Nordic Bioplastics Association Showcases Sustainable Innovations at Plastteknik Nordic Fair - Sollex blogThe Nordic Bioplastics Association is a Nordic platform and representative of the companies in the Nordic countries that produce, process, use or recycle bioplastics. NBF members exhibited their products at the Plastteknik Nordic fair and it was interesting to see new sustainable products and solutions: straws made of hay, compostable cups, bio bags for waste, biodegradable tools and packaging etc.

It was also great to see Sollex customers among the Nordic Bioplastics Association members who are thinking about the future and developing new biomaterials, solutions and technologies in the plastics industry using Sollex knives for plastic film manufacturing and recycling.

The most comprehensive Nordic resource on bioplastics that we can say is the NBF website. If you have any questions about bioplastics, material knowledge, types of bioplastics, applications and recycling, you will surely find the answer there. Learn all about bioplastics on their website
