Suppliers change packaging for many reasons. A new box supplier, a redesign, a cost reduction, or a sustainability initiative can all result in a different carton arriving at the receiving dock. The packing team notices because the cartons look different, feel different, and behave differently in the shredder. This article focuses on one situation only: when a supplier changes the cartons, and how the operation adapts.
Start with what changes. There are four common differences. The first is board thickness, where the new carton is thinner or thicker than the old one. The second is board type, where the new carton uses a different fluting or a different liner. The third is coating, where the new carton has a water-resistant or grease-resistant coating. The fourth is size, where the new carton is larger or smaller, which affects how it feeds into the machine. Each difference changes how the shredder performs.
The first adaptation is the feed rate. A thinner board feeds faster than a thicker one, so the operator may need to increase the speed to keep the output consistent. A thicker board feeds more slowly, and pushing it through too fast can cause a jam. Aircosan machines have variable frequency speed control on the industrial models, which lets the operator adjust the speed to match the material.
The second adaptation is the output form. A different board type may produce output that looks different. A board with a different fluting may expand differently, which changes the mesh structure. A board with a different liner may produce strips that are stiffer or softer. The operator may need to change the output form, or adjust the packing method, to compensate.
The third adaptation is the die life. A coated board wears the die faster than an uncoated board, because the coating is harder than the paper. A thicker board also wears the die faster, because it puts more load on the cutting edge. 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#. Die life is generally 1.0 to 1.3 million meters depending on material and usage. When the supplier changes the cartons, the die life estimate should be recalculated based on the new material.
The fourth adaptation is the sorting process. A new carton may have different tape, labels, or inserts. Those have to be removed before feeding, and the removal process may take more or less time than before. The operator should check the first batch of new cartons carefully to identify what needs to be removed.
The fifth adaptation is the storage. A different carton size may stack differently, which affects the space needed in the receiving area. A larger carton takes more space, and a smaller carton takes less. The storage layout may need to be adjusted to accommodate the change.
The sixth adaptation is the communication. When a supplier changes the cartons, the operation should communicate the change to the packing team before the new cartons arrive. That way the team knows what to expect and can prepare. Aircosan machines use one-button start, a pressure gauge that shows status clearly, and a panel that groups the controls in the order they are used. That design makes adaptation easier, because the operator can adjust the machine without a long learning curve.
The seventh adaptation is the testing. The first batch of new cartons should be tested in the shredder before the full shipment is processed. That test reveals how the new material behaves, and it allows the operator to adjust the settings before production begins.
What makes adaptation easier is the machine's tolerance for variation. 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. Material that is too wet, heavily contaminated, or laminated hurts performance and wears the blades faster. 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 overload protection: when a jam occurs, the machine automatically cuts power and stops, protecting the motor. That protection matters more when the material is new and unfamiliar. 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 team, the practical approach is to test the first batch, note how the new material behaves, adjust the machine settings, and communicate the change to everyone who handles the cartons. That process turns a supplier change from a disruption into a routine adjustment.
