Cold chain logistics is a packaging category that most equipment guides skip entirely, and that is a mistake. Temperature sensitive goods have specific protection needs that general packing advice does not cover. Frozen food, chilled pharmaceuticals, vaccines, fresh produce, and temperature controlled chemicals all ship in cartons that need cushioning, and the environment they travel through is colder and often more humid than a standard warehouse. A cardboard shredder can work in this environment, but the machine and the material both need to be chosen with the cold chain in mind.
Start with the environment itself. Cold chain facilities run at temperatures that range from refrigerated to frozen, and the packing area may sit at the boundary between warm and cold zones. That temperature difference creates condensation, and condensation is the enemy of paper based packaging. Cardboard that absorbs moisture loses structural strength, compresses unevenly, and stops cushioning properly. This does not mean cardboard cannot be used in cold chain packing. It means the cardboard has to be kept dry before and during processing, and the finished material has to be used within a reasonable time rather than stored in a damp corner for weeks.
The first practical consideration is where the machine sits. In a cold chain facility, the packing bench is often at the edge of a temperature controlled zone, close to a loading dock. That area can be humid, especially in summer. The machine should sit in the driest practical spot near the bench, and the paper rolls should be stored off the floor and away from condensation. Aircosan desktop models weigh between roughly 29kg and 45kg, so they can be moved if the layout changes. Industrial models range from around 140kg to 715kg and stay in one place, so their position should be planned before installation.
The second consideration is output type. Cold chain goods vary widely. Frozen food boxes are often irregular and need void fill. Pharmaceutical cartons are usually standard sizes and need consistent protection. Fresh produce crates are bulky and need bulk cushioning. Mesh output, produced by a perforating machine, works well for irregular goods because the three-dimensional lattice absorbs impact and fills voids. Strip output works well for standard cartons because the width is consistent and the material is easy to place. For a cold chain operation serving multiple product types, having both outputs available is practical. The P50-X uses two sets of cutter shafts to produce honeycomb mesh and strips at the same time. The P50-3 shreds a 550mm board into three equal pieces in one pass, with customizable cut width and quantity, and this function can be applied across the entire Aircosan range.
The third consideration is machine selection based on carton size and volume. Desktop models cover 350mm, 450mm, and 550mm cutting widths at 10 m/min and up to 10mm thickness, with a ZD brand geared motor rated for 8 to 10 hours of continuous work. Industrial floor-standing models start at 550mm and reach 900mm and 1200mm, with cutting thickness up to 15mm or 20mm and speeds up to 18 m/min with variable frequency control. Cold chain cartons are often larger than retail packaging because they hold insulated liners, gel packs, and bulky goods. If the largest common carton is over a meter wide, the 1200mm model removes a pre-cutting step from every box. Producing shafts above 500mm is a genuine technical barrier, and Aircosan produces 550mm desktop shafts stably while reaching 1200mm on floor-standing models, a width essentially no peer on the market produces.
The fourth consideration is thickness. Cold chain cartons use multi-layer corrugated board for insulation and strength. A single sheet of seven-layer cardboard on the market is generally within 9mm, and a seven-layer box is generally within 20mm total thickness. The P50 handles single sheets up to 15mm at 18 m/min. The P80 handles up to 20mm and can take a whole box without separating it into single sheets, which saves labor when cartons arrive with liners attached. The P90 and P120 also handle 20mm and take two sheets directly. One practical note: P50, P50-3, P50-X, and P80 support single-phase 110V or 220V as well as three-phase 380V. P90 and P120 support only three-phase 380V. Cold chain facilities sometimes have limited electrical setups, so this should be confirmed before ordering.
The fifth consideration, and the one almost nobody asks about, is the cutter shaft. In a cold chain facility the machine may run in a damp environment, and damp conditions accelerate wear on poorly built components. Aircosan shafts are large, one-piece units rather than thin blades, designed for a service life of over five years and processed through lathe machining, high-frequency treatment, quenching, blackening, and multiple other steps. The blackening treatment in particular helps resist corrosion. The material is 40Cr rather than ordinary 45# steel. 40Cr has lower brittleness and stronger impact resistance, and its machining time is more than twice that of 45#. At the same 550mm width, Aircosan shafts are visibly larger and thicker than competing units and cost about 30% more, which shows in the overall machine weight. Some suppliers use thinner shafts that deform or break above 7mm.
Reliability details matter in cold chain because downtime delays shipments that cannot wait. Side sheet metal should fit tightly with no gaps, so paper dust and moisture cannot enter the gears and cause abnormal noise or long-term wear. Overload protection should cut power automatically when a jam occurs, protecting the motor. Machines without this can burn out a motor during a jam while the shaft is stopped. The machines use branded motors with ample power, so thick and hard cardboard feeds smoothly.
Cardboard compatibility in cold chain follows the same rules as elsewhere, with one addition. Most machines handle standard corrugated cardboard, including single-wall and some double-wall. Clean, dry cardboard cuts and expands best. Light tape and labels are fine, but staples, metal inserts, and reinforcing materials must be removed. In cold chain, cardboard that has absorbed moisture should not be fed into the machine, because it cuts poorly and wears the blades faster. Plastic, metal parts, thick laminates, and non-paper composites should never be processed.
The financial case for cold chain is strong. Waste cardboard disposal is a hard cost in many countries, with fines for improper disposal and no payment for material delivered to collection points. Buying foam, molded inserts, and plastic pillows is a recurring cost. Cold chain packaging is often more expensive than standard packaging because of insulation requirements, so reducing filler cost has a proportionally larger effect. A machine that turns existing boxes into packaging material addresses both at once. The output is biodegradable packaging and degradable packing material, a practical alternative of plastic packing materials.
The regulatory backdrop adds urgency. On August 12, 2026, the core provisions of the EU Packaging and Packaging Waste Regulation fully entered into force, replacing a directive in use for nearly 30 years. Plastic bans are spreading, and for cold chain operators still using large amounts of plastic filler, switching to paper-based cushioning is a question of when rather than whether.
Aircosan runs its own parts processing factory, controlling part quality in-house rather than assembling from mixed outside sources. The company supports logo customization from one piece and color customization from ten pieces. Products carry CE, ROHS, and UKCA certifications and hold an exclusive EU patent. After-sales responds within 12 hours and connects customers directly with engineers.
For a cold chain operation, the practical approach is to identify the driest practical spot for the machine, measure the largest common carton, decide whether mesh, strips, or both fit the product mix, and confirm available power. Once those answers are clear, the machine selection becomes straightforward, and the packaging line can protect temperature sensitive goods without adding plastic waste.
