Cold storage wasn’t something most people thought about before 2020. But the logistics and requirements of shipping COVID-19 vaccines changed that. And cold storage solutions are essential for more than just vaccines; medicine to food also require them. The problem is that boxes that are cold storage-compatible aren’t environmentally-friendly, since they often use Styrofoam or other plastics to prevent temperature loss. That’s changed with U.K.-based Softbox Systems‘s Tempcell ECO, introduced in June 2020. The single-use box can keep its contents temperature-stable for 72 hours without using traditional insulators, thanks to Softbox’s corrugated cardboard insulating technology called Thermaflute. And unlike Styrofoam or other plastic-based insulators, Thermaflute, because it is 100% paper-based, is 100% recyclable.
