"Keep it cold" hides two very different jobs.
Frozen shipping has to hold well below zero for the whole route. Chilled shipping has to stay in a narrow window above freezing, which means it can fail from being too cold as much as from being too warm. That is why coolant is not interchangeable: copying a frozen configuration onto a chilled shipment is one of the most common ways to damage otherwise fine goods.
Our cellulose insulation serves both - even in one shipping box, but the specification around it, coolant quantity, placement and hold time, is set to your target temperature and real route. The most useful thing you can tell us is the exact window.
