In discussing sustainability, the article jumps from talking about recyclable plastics (currently only 9% of plastics are recycled) to recyclable corrugated (60-90% is currently recycled). The difference is that most plastics are used for primary packaging and therefore get contaminated by contact with the product. The corrugated market, with only a single polymer (cellulose), is much easier to manage than flexible packaging with its multi-layer materials and the need to separate and clean them before processing.
Brands are making strenuous efforts to improve their sustainability image by using more PCR (post consumer resin), adopting bio-based resins, and other 'green' initiatives. But Jeff W touched on a neglected focus for inkjet printing - late-stage customization of packaging, using inkjet as well as conventional printing: this will to allow shorter runs, avoiding unnecessary production, and therefore scrap and greenhouse gases. A good value proposition to sell to brands today.

Chris - you are correct in pointing out that not all sustainability initiatives have the same level of impact. For any application segment, including packaging, there are an array of options from physical materials to the workflow that all have an impact. Mary covered a lot of ground in her article, but there is a lot more to cover - particularly with respect to opportunities for a lower footprint process.
