For businesses running regular cold chain operations, reusable dry ice packs deliver 40–55% lower per-shipment refrigerant costs and reduce single-use plastic waste by up to 99%. Here is everything you need to make them work.
On a 40°C January day in Brisbane or Perth, the radiant heat load on an exposed cold chain package can match or exceed the conductive heat ingress through the packaging walls. Here is the engineering explanation — and what to do about it.
R-value is the single most important technical specification for any insulated packaging product. Understanding it lets cold chain buyers make evidence-based decisions, calculate true total cost of ownership, and build systems that reliably perform in Australian conditions.
Buying too few refrigerant packs means your shipment fails. Buying too many wastes money on every delivery. This step-by-step thermal load calculation gives you the exact number based on your specific packaging, ambient temperature and transit time.
Choosing between dry ice packs and gel ice packs is an engineering decision driven by payload temperature, transit duration and ambient conditions — not habit or price. Here is the framework to get it right every time.
Understanding latent heat explains why a 1 kg phase change material pack maintains your shipment’s temperature far longer than 1 kg of cold water — and why selecting the right phase change temperature is one of the most impactful decisions in cold chain design.
