Nexam Chemical launches additive masterbatches for recycled PET, thus achieving new success in projects with additives for recycled PET. Nexam has received its first production order worth SEK 0.5 million for thermoformed food packaging.
Nexam Chemical has since the beginning of 2022 worked in a project with an Israeli food packaging manufacturer with the goal of increasing the amount of recycled PET in their products.
Increases Intrinsic Viscosity of rPET
Nexam’s additive enables the use of a larger amount of recycled PET in the packaging than would otherwise have been possible. The product is now fully developed and technically approved.
The new additive masterbatch facilitates the upcycling of low IV rPET obtained from trays or fibers into a higher intrinsic viscosity (IV) rPET grade. This masterbatch effectively reduces brittleness, enhances melt strength, and stabilizes the process, resulting in faster throughput.
- NEXAMITE®M021200 is an IV enhancer in PET carrier, provides a highly efficient increase in intrinsic viscosity (IV) and enables the upcycling of rPET. It allows for the recycling of PET into applications that require high IV. This additive is suitable for use in all rPET and PET applications and has been approved for use in food packaging applications. Moreover, it is free from epoxy and epichlorohydrin derivatives.
- NEXAMITE®M992000, a linear IV enhancer in PET carrier, provides an increase in intrinsic viscosity (IV) for enhanced properties. It effectively reduces acid concentration, leading to improved hydrolysis resistance. Additionally, this additive is free from epoxy and epichlorohydrin derivatives.
- NEXAMITE®F101 is an IV enhancer specifically designed for fiber spinning applications. It enables the recycling of fibers from both fiber-to-fiber and tray-to-fiber processes. With this enhancer, it becomes possible to use lower IV rPET for fiber spinning without the need for solid state polymerization (SSP). NEXAMITE®F101 is also free from epoxy and epichlorohydrin derivatives.
“
We see an increasing interest in our products in this type of application and we have several ongoing projects in Europe. This type of food packaging, together with our additives in recycled PET for fiber, are two areas with great potential,” says Ronnie Törnqvist, Nexam Chemicals CEO. “
Our additives open the door for the majority of actors to use recycled plastic at a low cost in the manufacture of products that are aimed at areas with higher demands on both quality and durability. In this case, food packaging in the food industry," says Ronnie Törnqvist.
Reactive Recycling is a molecular tool to simplify and improve today’s recycling. Recycled plastic has lost some properties compared to new raw material. In order to better use recycled plastic, you simply have to improve properties that have been lost, which you do with the help of additives, so-called additives. The recycling process becomes faster, simpler, and more cost-effective compared to several other methods.
