Packaging has one job -to protect the product until it reaches the customer. The material produced by a cardboard shredder looks protective, but looking protective and being protective are different things. The only way to know whether the output is protective enough is to test it. Drop testing is the most common method, and it is simple enough that most operations can do it in-house.
The first thing to understand is the test method. A drop test involves packing a product in the same way it would be packed for a customer, then dropping the package from a set height onto a hard surface. The height depends on the shipping method and the product weight. A common standard is a drop from about 76cm for packages under 10kg, and a higher drop for heavier packages. The package is dropped on different faces -bottom, top, side, edge, and corner -because different faces experience different forces in transit.
The second thing is the sample size. One package is not enough, because the result varies. A common approach is to test five packages and confirm that all five pass. If one fails, the packing method needs adjustment.
The third thing is the inspection. After each drop, the package is opened and the product is inspected. The inspection looks for damage to the product, damage to the packaging, and movement of the product inside the package. Movement is a sign that the cushioning material is not holding the product in place, even if the product is not damaged yet.
The fourth thing is the pass criteria. The pass criteria depend on the product. A fragile ceramic needs to arrive without cracks. An electronic device needs to arrive without functional damage. A garment needs to arrive without wrinkles. The criteria should be defined before the test, so the result is not subjective.
The fifth thing is the adjustment. If the test fails, the packing method is adjusted. The adjustment may be more material, a different output form, or a different carton size. Mesh output absorbs more impact than strip output, so switching from strips to mesh may fix a failure. A larger carton with more material may also fix a failure, but it adds shipping cost, so the smaller adjustment is usually better.
The sixth thing is the material. The cushioning material produced by the shredder has to be consistent for the test to be meaningful. 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#. A stable shaft produces consistent output, which means the test results are reliable.
The seventh thing is the documentation. The test results should be recorded -the date, the product, the packing method, the drop height, the result, and any adjustments. The record shows whether the packing method is stable over time and whether changes to the material or the carton affect the protection.
The eighth thing is the machine's role. The shredder's output is one variable in the packing method, but it is not the only one. The carton, the product, and the packing technique all affect the result. 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. That cleanliness keeps the output consistent, which makes the tests more meaningful. Aircosan machines use overload protection -when a jam occurs, the machine automatically cuts power and stops, protecting the motor. That protection means the machine does not produce a batch of inconsistent output after a jam, which would affect the test results. 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. 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 define the test method, test five packages, inspect the result, and adjust the packing method if needed. Those four steps confirm that the output is protective enough, and they prevent the returns that come from inadequate packaging.
