Shipping Chilled Food in Summer: How to Keep Fresh Goods Cold in Transit
Summer is the most demanding quarter for shipping food. What almost runs by itself in winter becomes a real stress test at thirty degrees inside a delivery van. Anyone shipping fresh or frozen goods finds out right now whether their packaging holds what it promises. So here is what matters most, so that chilled food arrives reliably even in the heat.
Why the heat is not the real problem
High outside temperature is only the visible part. What counts is how long the shipment is in transit and which temperatures it actually passes through on the way. A parcel sits in the sorting centre on Friday, spends hours in a heated vehicle and may still wait on the doorstep. It is not the hottest moment that determines the result, but the sum of the hours outside the cold store. Anyone who only considers the peak value and not the duration underestimates exactly the conditions that count in summer.
What carries chilled food shipping through summer
Three things decide whether the goods stay cold. First, the insulation that holds the temperature inside rather than slowly releasing it. Second, the amount and preparation of the coolant, matched to the actual transit time. And third, packaging that fits the product precisely, because too much empty space means more area to cool. Our packaging starts exactly here. The insulation is cellulose based and keeps your goods reliably chilled or frozen for more than 48 hours.
Sustainable and summer-proof are not opposites
Many still associate reliable cooling in summer with polystyrene. That is no longer necessary. Our solutions are made from more than 97 percent recycled paper and can be disposed of entirely in the paper stream, with nothing for your customers to separate. They match the performance of conventional insulated packaging. Good cooling performance in the heat is no longer a question of material, but of correct design.
How to prepare your summer shipping
Look at how long your shipments are in transit on average and in the worst case, and design the packaging for that duration, not for the ideal case. Pre-condition your coolant in good time so it delivers full performance inside the parcel. And test under real summer conditions before the hot weeks arrive, not once the first complaint lands.
