Packaging material prices move, and they usually move up. Plastic filler tracks petroleum markets. Paper filler tracks pulp markets. Both are affected by energy costs, transport costs, and supply chain disruptions. When prices rise, operations that buy finished filler absorb the increase directly, and the effect shows up in the monthly accounts. A cardboard shredder changes the exposure because the main input is cardboard that is already on site.
Start with where the price exposure comes from. There are four sources. The first is raw material cost, where the input for purchased filler becomes more expensive. The second is energy cost, where production and transport become more expensive. The third is supply constraints, where limited availability pushes prices up. The fourth is currency movements, where imported materials cost more when exchange rates shift. Each source affects purchased filler, and each one adds to the cost of every box packed.
The first way a shredder reduces exposure is by changing the input. Purchased filler is made from raw materials that are subject to market prices. Cardboard cushioning is made from used boxes that have already been paid for as part of incoming goods. The marginal cost of that cardboard is mostly the cost of operating the machine. When filler prices rise, the shredder's advantage grows because the gap between purchased material and on-site production widens.
The second way is by reducing the volume of purchased material. Even if the operation still buys some filler for products that cannot use cardboard cushioning, the volume is smaller. A smaller volume means less exposure to price increases, because the increase applies to fewer units. This is a proportional benefit. An operation that replaces seventy percent of its filler purchases reduces its price exposure by roughly the same proportion.
The third way is by making costs more predictable. On-site production has costs, but they are mostly fixed. The machine, the paper rolls, and the labor are known quantities. Purchased filler has costs that vary with the market. For operations that plan budgets months in advance, predictable costs are easier to manage than variable ones, even if the predictable cost is not always the lowest.
The fourth way is by supporting contract negotiations. When an operation can produce cushioning on site, it has an alternative to purchased filler. That alternative gives it leverage in negotiations with filler suppliers, because the operation can credibly say it will switch if prices rise too far. This leverage is hard to quantify, but it affects the terms the operation can negotiate.
The first thing that makes this work is the cutter shaft. 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. A machine that lasts longer spreads its cost over more material, which improves the economics of on-site production.
The second thing is machine selection. 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. These are the right choice for operations with moderate volume because they are easy to install and operate. Industrial 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. Larger operations with high volume use industrial models because the savings scale with volume. Producing shafts above 500mm is a genuine technical barrier, and Aircosan produces 550mm desktop shafts stably while reaching 1200mm on floor-standing models.
The third thing is output flexibility. Operations that produce only one output form may still need to buy some filler for products that need a different form. A dual-output machine covers more product types, which reduces the volume of purchased filler further. 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 fourth thing is overload protection. Aircosan machines use overload protection: when a jam occurs, the machine automatically cuts power and stops, protecting the motor. Many machines on the market lack this, and a jam can burn out a motor while the shaft is stopped. A machine that fails during a price spike forces the operation back to purchased filler at the worst possible time. Overload protection prevents that scenario.
The fifth thing is panel fit. 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. A machine that stays clean internally needs less maintenance, which keeps the on-site production running when it is needed most.
The sixth thing is material input. 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. Operations that generate cardboard continuously have a ready supply, which is what makes the input cost so low.
The regulatory backdrop adds another dimension to price exposure. 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 businesses still using large amounts of plastic filler, switching to paper-based cushioning is a question of when rather than whether. Plastic filler prices may also rise as regulation tightens supply, which makes the switch more urgent. The output from a cardboard shredder is biodegradable packaging and degradable packing material, a practical alternative of plastic packing materials, and it supports reuse cartons and paper recycling.
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 an operation facing price increases, the practical approach is to calculate the current annual spend on purchased filler, estimate the share that could be replaced with on-site production, and compare the cost of that production to the current price. If the price of purchased filler rises, the comparison improves. That calculation is what turns a price increase from a problem into a reason to make the switch.
