Plastic is a bundle of materials with many economic and ecological advantages and is often used for food packaging. In order to reduce the plastic waste Evonik wants to enable the transition from a linear to a circular plastic value chain. In order to increase the recycling rates optimal sorting and recycling processes are required. In addition, simply designed mono material packaging is the key to avoid incineration of hard to recycle packaging. Heat seal coatings often play an important role for food packaging which come with heat sealable lid structures. Thus, they should be considered when designing a sustainable food packaging.
Evonik’s DEGACRYL® HS heat seal binders offer great advantages for food packaging when designed for recycling.
- Enable NIR sorting of plastics coated with DEGACRYL® HS based heat seal coatings
- Improve recycling efficiency by enabling mono material packaging
Circular Plastic Program
Evonik is pooling its activities for circular plastics in a global program. As part of the transition to a circular economy, the company offers its customers solutions for all stages in the polymer value chain.
"There is a real future for circular plastics in our view, so we're stepping up our focus on this topic at various levels: using sustainable raw materials in the production of our products, developing new recycling technologies, and reviewing established production routes and inputs along the entire value chain. The specialty chemicals industry has the expertise to facilitate the circular economy through mechanical and chemical recycling of plastics and rubber."

Enable sorting of plastic material coated with DEGACRYL® HS based coatings
DEGACRYL® HS binders can achieve high heat seal strengths already at low coating weight due to their unique hybrid methacrylic polymers composition. It is designed to have no impact on the sorting process by standard NIR technology and the respective plastic material can be assigned to the dedicated recycling stream.
Improve recycling efficiency by supporting mono material packaging
It is difficult or even not possible at all to mechanically recycle composite materials consisting of multi-layer films. Key to increase recycling rates is the use of mono material packaging.
Here, also our DEGACRYL® HS grades can support. With our universal heat seal binders, it is possible to design a mono PET packaging of highest quality. Due to the direct adhesion properties on PET as well as great sealability against PET it is possible to substitute the widely used multilayer composites by mono material packaging. Our transparent heat seal binder even enables the design of transparent PET lidding, widely used for fresh food packaging.
