CCL Launches EcoFloat WHITE Shrink Sleeves for Light Sensitive Products
- EcoFloatĀ® WHITE enables the transition from white HDPE packaging to transparent PET bottles and containers, combined with a white opaque sleeve.
- Low density sleeve material supports float separation from PET during the recycling process.
- Increases yield of high-quality, food-grade PET flakes for bottle-to-bottle recycling.
Toronto, Canada – CCL Label, a global leader in specialty label, security and packaging solutions, has introduced a new version of its proven EcoFloat low-density polyolefin sleeve material: EcoFloatĀ® WHITE.
“EcoFloat WHITE will enable greater recyclability for dairy packaging and other products that are light sensitive – we expect it to be a game changer. The dairy industry often uses HDPE bottles for bottles containing yoghurt and probiotic drinks or similar products. However, these white HDPE bottles are rarely recycled back into food grade applications for a number of reasons, including strict food contact regulations – so the bottles leave the packaging loop,” says Guenther Birkner, member of the management team at CCL.
“We have seen a big trend in the Food and Beverage but also Home and Personal care industries to move from HDPE to PET, which works well in terms of recycled content for food packaging, and it is our goal to support this with a functional product decoration.
Millions of bottles can now be recycled in a closed loop
“Legislation such as the European Green Deal and the Packaging and Packaging Waste Regulation will drive ‘design for recycling’ or eco-design in the coming years, every brand has to come up with packaging that is actually recyclable,” explains Marika Knorr, Head of Sustainability and Communication at CCL Label. “Until now, many white HDPE bottles have left the closed loop for food packaging and are lost for reuse in a circular senseā.
By using PET bottles with a white sleeve, companies achieve two benefits at the same time. The entire bottle is fully recyclable, while still achieving the same look and feel that marketing is looking for – to maximize the messages and mandatory information given to consumers on the bottle. Millions of additional PET bottles are recycled and turned into a new one – giving the packaging many “extra lives”.
Additional light blocking barrier can be achieved with carbon-free inks
A key requirement for dairy products is light blocking properties to keep the product fresh and maximise shelf life. In the past, this light-blocking barrier was often achieved with a layer of black or silver ink, which is essential for protecting the products but could also be detrimental to sorting and recycling, as the standard near-infrared detection system commonly used could have difficulty detecting the underlying material.
“Since 80 percent of recycling is actually sorting, we had to make sure that our solution was detectable by the standard technology used in the recycling industry today,” says Norbert Fenkart, who heads the research and development (R&D) department at CCL’s sustainable sleeve label center in Dornbirn, Austria. “We use carbon-free inks to create additional lightblocking properties on the sleeve. These work well in NIR detection as we have seen in tests* and the underlying rigid PET bottle is detected and the bottle is sorted into the correct waste stream.”
The sleeve also helps with the crucial sink/float process step in PET recycling because it is made from a low-density polyolefin material that floats. It automatically separates from the PET bottle flakes and the density separation is very simple and clean: the heavier PET flakes sink to the bottom of the container, while the floatable material collects at the top of the container and can be easily captured and removed. The recycler is left with high quality, clean PET flakes that can be recycled back into food grade packaging for the dairy and other industries.
The transparent EcoFloatĀ® sleeve material has been commercialised for over two years and has been adopted by many international brands to increase the recycling of their packaging containers. Click here for more information on EcoFloat.
