Packaging performance is usually evaluated at room temperature, which is where the packing line operates. The shipment does not stay at room temperature. A box packed in a warm warehouse may sit on a cold loading dock, travel in an unheated truck, and wait in a freezing distribution center before it reaches the customer. Cold changes how materials behave, and packaging that performs well in the warehouse may perform differently in the back of a truck in January.
The most visible effect of cold is brittleness. Paper becomes stiffer and less flexible as temperature drops, which means it conforms less easily to product shapes and cracks more readily under sharp impact. Plastic film becomes brittle and can shatter rather than stretch. Foam becomes rigid and transmits impact rather than absorbing it. Each material responds differently, but the direction is the same: cold reduces flexibility, and reduced flexibility reduces protection.
The second effect is dimensional change. Materials contract in cold, and packaging that fits tightly at room temperature may become loose as the material shrinks. Loose packaging allows the product to move, which reintroduces the damage risk that the packaging was supposed to eliminate. This is particularly relevant for products that are packed with tight tolerances, where a small change in dimension changes the fit.
The third effect is on adhesive and closure performance. Tape adheres less well in cold, and closures that rely on adhesive may fail during transit. This is why winter shipments sometimes arrive with tape peeling, which is not a packaging failure in the traditional sense but a temperature-related failure that looks the same to the customer.
The fourth effect is condensation. When a cold package moves into a warm environment, moisture condenses on the surface. Paper packaging absorbs that moisture, which softens it and reduces its strength. This is why packages that travel through cold conditions sometimes arrive looking damp, even though they were dry when packed. The condensation is not a defect in the material, but it affects how the material performs at the end of the journey.
Aircosan's kraft honeycomb paper roll performs reasonably well in cold conditions because paper remains functional at low temperatures, even though it becomes stiffer. It is made from virgin kraft paper pressed into a 3D honeycomb structure, and it is zero-plastic, 100% recyclable, and biodegradable, with FSC certification. It comes in 70g and 80g, widths of 300mm, 380mm, and 500mm, and roll lengths from 20m to 250m, with an expansion ratio of 1:7 and an average tensile strength of 13.86N. Each roll carries a batch number engraved inside for traceability. Paired with the electric honeycomb paper dispenser, it expands and cuts automatically at up to 25m/min, which is useful in cold environments because the material does not need to be stretched by hand, a process that is harder when the paper is stiff. The dispenser runs on 110V or 220V, handles both honeycomb paper and liner paper, and comes in an H30 standard model and an H30 cutter model with foot control available.
The honest limitation is that no paper material is immune to cold. At extreme temperatures, paper becomes difficult to work with and its cushioning performance declines. For shipments that pass through very cold conditions, additional protection or a different material may be needed. The point is that cold is a variable worth considering rather than an afterthought.
The practical takeaway is to test packaging under the temperature conditions that the shipment will actually encounter, not just the conditions in the packing facility. For operations shipping to cold regions or through cold seasons, a cold-chamber test reveals issues that room-temperature testing misses. Most operations have never run one, which is why winter damage rates sometimes spike without an obvious cause.
