Hockenheim, 12.11.2018 – The sustainability and recyclability of their solutions is a key issue for the packaging experts at Sonoco Consumer Products Europe. Advanced In-Mould-Labelling (IML) technology and a focus on mono-material enable them to produce plastic packaging solutions that are almost completely recyclable. The cyclos-HTP institute for recycling and product responsibility recently tested Sonoco’s polypropylene (PP) packagings that are currently being used on the market by several clients. What it found: the Sonoco packaging solutions offer an extraordinarily high recyclability of close to 100 percent.

Cyclos-HTP, based in Aachen, was founded in 2014 with the self-proclaimed goal of classifying, surveying and testing the recycling capabilities of packaging and other goods. The institute analyses a given packaging’s materials and assesses how it is actually recycled in the industrial-scale recycling streams established in Germany and other European countries. To this end, cyclos-HTP runs the packaging solutions through real sorting systems, a testing concept that piqued Sonoco’s interest. “When we design new packaging solutions, we consider three main aspects: Does the new solution safely protect sensitive goods? Does it fit in with and simplify consumers’ everyday lives? But equally important: How can we make the packaging as sustainable as possible by using recyclable materials?” says Andreas Rothschink, Sales Director Sonoco Europe. “For our plastic packaging solutions, we rely on high-quality PP. By working with cyclos-HTP, we received solid proof that our packaging solutions have a recyclability of close to 100 percent and can actually be recycled just as we intended.”

The result: almost completely recyclable packaging solutions

cyclos-HTP tested a packaging that is similar to solutions used by a variety of brands. Its base is a Sonoco IML container, which is covered by a plastic lid and an aluminium membrane produced by other manufacturers. The final score after testing showed that Sonoco’s container has a recyclability level of up to 98 percent, with small deductions for printing colour and finish. Together with the aluminium membrane and the PET-plastic lid, the tested solution had an overall recyclability level of 88 percent. “The test result shows: if clients want to raise the recyclability of their packaging to more than 90 percent, mono-material is key,” says Andreas Rothschink. “We can provide both containers and lids made from PP. Customers can also use PP membranes for products that don’t require high barrier properties, such as chilled food or dairy products.”

Mono-material packaging for high recyclability

Sonoco’s IML containers are used for a wide variety of food – from snacks like precooked sausages to fresh dairy products such as yoghurt. In the dairy segment, the mono-material packaging outdoes other common solutions such as plastic containers wrapped in cardboard for a more naturalistic look. Made from two entirely different material groups, the cardboard wrap-around and the container need to be separated completely to be recycled. Many of these packagings, however, end up in the recycling systems unseparated, which is why they are attributed recycling rates of under 50 percent.

For Sonoco, one major takeaway from the cyclos-HTP analysis was the benefits of mono-material packaging. “The analysis confirms one principle behind our packaging development: given the current status of the German and other European recycling systems, the best way that we can ensure our packaging’s recyclability is to use as few different materials as possible,” says Andreas Rothschink. “To further increase the recyclability of its plastic packaging, Sonoco will continue to focus on mono-material solutions with a recyclability of close to 100 percent.”
