This document summarizes the RecyCold cool packs, which are more sustainable alternatives to traditional gel packs for shipping temperature-sensitive products. The cool packs use a biodegradable cooling gel contained in a paper pouch that can be recycled. They provide effective temperature control, freeze faster than conventional gel packs, and allow for a unique unboxing experience while being environmentally friendly. At the end of their use, the gel can be disposed of down the drain and the paper pouch recycled.
