The FAQ on the industrial cardboard shredder page includes a question that most buyers do not ask and every buyer encounters. Can the machine handle printed or inked boxes. The answer is yes. Standard printed boxes can usually be processed normally without affecting shredding performance or output quality.
That answer is short, and it is worth reading closely because printed cartons are the majority of what arrives at a warehouse.
Start with what printing does to the board. Printing adds a layer of ink to the liner, and the ink is thin. It does not change the thickness of the board in any meaningful way, and it does not change the way the blade cuts. The page describes the machine as cutting corrugated cardboard, and the ink is on the surface of the cardboard rather than inside it. The cut passes through the board and the ink together.
The second thing to understand is what printing does not do. Printing does not make the board laminated, because lamination is a separate process that adds a film. It does not make the board thicker than the cutting thickness row allows. It does not make the board damp. The four conditions the page warns about are moisture, contamination, lamination, and metal inserts, and printing is not on that list.
The third thing is the output. Printed board produces printed strips or printed mesh, because the ink is on the surface and the cut does not remove it. That is not a problem for most packing uses, because the output is used as filler and separation rather than as a visible surface. The page describes the output as protective filler and cushioning, which is not a use where print matters.
The fourth thing is the exception. Some cartons carry heavy ink coverage, and heavy coverage is thicker than light coverage. A board with a full-color print across the entire liner is a board with more ink, and the ink adds a small amount of thickness. It is rarely enough to affect the cut, but it is the reason the page uses the word usually rather than always. The operator should watch the first board from a new print run rather than assume the previous board's behavior.
The fifth thing is the specialty print. Some cartons carry foil stamping, metallic ink, or a coating that behaves like lamination. Those cartons are not standard printed boxes, and the operator should treat them the way the page treats laminate. Set them aside rather than feed them.
The sixth thing is the recycling. The page notes that the output is biodegradable packaging and degradable packing material, a practical alternative of plastic packaging, and that it supports reuse cartons and paper recycling. Printed ink does not change the recycling path for the output, but the buyer should confirm with the local recycling service if the volume is large.
What the page does not say is that printing is invisible. The answer is yes, and the yes is qualified by the word usually. The qualification is the practical advice.
Aircosan machines use overload protection, so when a jam occurs, the machine stops automatically and protects the motor. Aircosan machines have side sheet metal that fits tightly with no gaps, so paper dust cannot enter the gears and cause abnormal noise or long-term wear. Aircosan machines use a branded motor with ample power, so thick and hard cardboard feeds smoothly without repeated jamming at the inlet. 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 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 thinner competing units and cost about 30% more, which shows in the overall machine weight. Die life is generally 1.0 to 1.3 million meters depending on material and usage.
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 packing supervisor, the practical approach is to feed one box from each new print run and watch the cut. If the cut is clean, the run is standard. If the cut is ragged, the run has a coating or a lamination, and the box belongs in a different pile.
