Tape and strapping are the last things most people think about when they add a cardboard shredder to a packing area. The machine produces cushioning material, not tape, so the connection is not obvious. But the way a box is filled affects how it has to be sealed, and the way it has to be sealed affects how much tape and strapping the operation uses. This article focuses on one thing only: how a shredder changes tape and strapping consumption, and why that change shows up in the packing budget.
Start with why tape consumption changes. Tape is used to close a box and to keep the contents from shifting. When the contents shift during transit, the box bulges, and the tape has to hold more stress. Boxes that are under-filled with loose material bulge and split more often, which means the packer uses extra tape to reinforce them. Boxes that are filled with material that holds its position stay square, which means the standard tape pattern is enough.
The first change a shredder brings is better fill. Paper cushioning produced by a perforating machine expands into a three-dimensional structure that fills the space around the product and holds its position. That fill keeps the product from shifting, which keeps the box from bulging, which means the tape does not have to work as hard. The packer uses the standard tape pattern rather than adding extra strips for reinforcement.
The second change is the elimination of the void. Purchased filler sometimes leaves gaps because the material does not fit the space. Air pillows compress, bubble wrap shifts, and foam inserts do not always match the product shape. Paper cushioning can be produced in the size needed and placed where the gap is, which eliminates the void. A box with no void does not need extra tape to compensate for movement inside.
The third change is the reduction in over-packing. When material is hard to control, packers use more than necessary to make sure the box is full. That over-packing puts pressure on the box walls, which can cause the seams to open. Paper cushioning is easier to control, so packers use the right amount, which means the box is filled correctly rather than over-filled.
The fourth change is the relationship with strapping. Strapping is used for heavy or bulky boxes that need extra support. When a box is filled correctly, the strapping holds the box together rather than compressing loose material. That means the strapping tension can be lower, which reduces the risk of crushing the contents and reduces the amount of strapping material used per box.
The fifth change is the re-tape rate. Boxes that bulge or split have to be re-taped, which uses additional tape and additional labor. Boxes that stay square do not need re-taping, so both the tape and the labor are saved. The re-tape rate is not usually tracked, which is why the saving is invisible until someone adds it up.
The sixth change is the tape pattern itself. Some operations use a single strip of tape on the seam, and some use an H-pattern with strips on the seam and the edges. The H-pattern uses more tape but provides more reinforcement. When boxes are filled correctly, the single strip is often enough, which means the operation can move from the H-pattern to the single strip. That change is small per box but significant across volume.
The seventh change is the perception of the box. A box that is filled correctly looks solid when it is closed. A box that is under-filled looks soft, and the packer responds by adding tape to make it feel more secure. Paper cushioning gives the box a solid feel, which reduces the instinct to add extra tape.
What makes these changes possible is the material's behavior. Aircosan machines produce output that holds its shape, which is what keeps the box square. 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#. A stable shaft produces consistent output, which means the fill is predictable from box to box. 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. That flexibility lets the packer match the fill to the box rather than forcing one material into every shape.
Aircosan machines use overload protection: when a jam occurs, the machine automatically cuts power and stops, protecting the motor. A jam interrupts the fill process, which is when packers tend to over-fill or under-fill. Preventing jams keeps the fill consistent, which keeps the tape consumption consistent. 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 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 measure tape and strapping consumption for a month before the shredder is installed, then measure it again for a month after. The difference is usually visible, and it is one of the savings that does not appear in the machine's specification sheet.
