Systems Labelling claims innovation could end polypropylene ‘jazz’ days
Systems Labelling has developed a completely removable in-mould label, and claims the product could dramatically increase currently poor UK polypropylene (PP) recycling rates.
Systems Labelling has developed a completely removable in-mould label, and claims the product could dramatically increase currently poor UK polypropylene (PP) recycling rates.
Carrying the trademarked name R-IML, the new product can be moulded at standard dwell times and temperatures, and therefore had no impact on moulding processes.
Steve Pickford, CEO, Systems Labelling, said: “We have developed a patent-pending solution that will mould at the same temperatures and dwell times, while performing in moist, chilled, damp or microwave conditions.”
He added: “This innovation will contribute directly to the sustainability objectives set out in the Courtauld Commitment and will revolutionise the inmould labeling market.”
According to WRAP, PP is the third most commonly used polymer found in UK household waste after high-density polyethylene (HDPE) and polyethylene terephthalate (PET).
Virgin PP preference
PP is used to create injection-moulded pots, containers and lids for large volumes of food and dairy products, as well as cosmetic and household goods. But Systems Labelling said that the variety of different grades and colours of PP produced – contrary to the other two main polymers, listed above, which are used in milk and drinks products – meant it was more difficult to recycle.
“Until now, there has been little incentive for UK industries to consider the benefits of reducing the dependence on virgin PP in the manufacture of food packaging, and at the same time, divert waste from landfill and boost the UK market value of recycled PP,” Systems Labelling said.
Currently, most PP waste was sent to landfill due to low demand for ‘jazz’ or black/grey pellets, Systems Labelling said, given that printed decorations (inmould labels) were difficult to remove completely after use. The company said that the ability – brought by its labeling breakthrough – to recycle clear or white polypropylene would create commercial value for all PP industry stakeholders, and also ‘displace’ use of virgin resin in consumer product packaging for colour-sensitive applications.
