Completing the circle in moulded packaging
Mark Holmes reports on initiatives and new equipment from injection moulding machinery manufacturers that are helping packaging moulders meet sustainability goals
Using reduced levels of material through light- weighting and high production efficiencies has been the mainstay of the injection moulded packaging sector for a number of years. However, moulders are now required to embrace issues of sustainability, such as greater traceability and recyclability, as well as increased use of post-con- sumer recyclates in their products. Although the Covid-19 global pandemic is creating additional uncertainties as to how to maintain the balance between sustainability and security going forward, the major injection moulding machinery manufac- turers are stepping up to the challenge. The circular economy and resource efficiency
remains the biggest challenge for the packaging sector in the plastics injection moulding industry, as well as society in general, according to Arburg.

“One of the challenges of the discussions taking place at this time is that plastics is often seen only in terms of being a waste product,” says Bertram Stern, Packaging and Circular Economy Manager. “Instead, plastics must be used sensibly and respon- sibly. In the best-case scenario, it belongs in a sealed recycling circuit. Verstraete IML’s Holy- Grail2.0 technology is such an innovative solution for single-type sorting to get high quality recyclates. Using digital watermarks, any information can be placed ‘invisibly’ on a label, thereby providing the product with a ‘digital passport’ with relevant information on recycling. Arburg has already produced IML cups with HolyGrail2.0. A circular economy can only function properly if all elements within the value-added chain work properly. Our strategy in terms of resource efficiency and circular
