We designed a soft-side case with a top-loading tray insert constructed of expanded polypropylene foam engineered to increase air flow. Gel packs were inserted into the case walls. We customized the insert to protect the payload, while allowing the temperature to be maintained within the critical tolerance. We built the cases of ballistic nylon strong enough to withstand world-wide travel, handling, and environmental fluctuations. The outer, rectangular case was strengthened with firm polyethylene foam sewn into the lining of waterproof nylon that was added to keep the cold air inside. Molded plastic corners were also attached to the exterior to maintain shape and ruggedize the solution.
For ease of handling, we added recessed inline-skate wheels doubled up to support the heavy payload, and a handle with an ergonomic rubber grip for comfort. The final addition of document pouches and silk-screened branding and handling information established these cases as the optimal packaging solution for the client's needs.
