Electricity cost is a small line item in most packing operations, and it is usually ignored. The cost is small because the equipment draws little power. But the comparison between a honeycomb paper machine and the equipment it replaces is worth understanding, because the difference is larger than it appears.
The machine that a honeycomb paper machine replaces is not a single machine. It is the combination of equipment that handles purchased cushioning. That combination may include a bubble wrap dispenser, an air pillow inflator, or a foam cutting station. Each of those draws power, and the total draw is what the honeycomb paper machine replaces.
What the Machine Draws
A honeycomb paper machine runs on standard AC220V/50HZ at 1.5kW total power. The draw is the machine's full load, and the actual draw during operation may be lower because the machine does not run at full load continuously.
The 1.5kW figure is modest. A typical air pillow inflator draws more than that, because the inflator has a heating element. A foam cutting station may draw more, depending on the cutting method.
How the Comparison Works
The comparison is between the honeycomb paper machine's 1.5kW and the total draw of the equipment it replaces. If the replaced equipment draws 3kW, the honeycomb paper machine saves 1.5kW per hour of operation.
The saving is small per hour. Over a year of operation, the saving accumulates, and the accumulated saving is what shows up on the electricity bill.
Why the Saving Matters More Than It Appears
The saving matters because the electricity cost is not the only cost that changes. The honeycomb paper machine has no compressor, no heating element, and no adhesive system. Each of those components has its own maintenance cost, and the elimination of the components eliminates the maintenance.
The saving also matters because the electricity cost is predictable. The machine's draw is constant, which means the electricity cost per hour is constant. The predictable cost is easier to budget than the variable cost of the replaced equipment.
How to Calculate the Saving
The calculation is straightforward. The machine's draw is 1.5kW. The replaced equipment's draw is the sum of the equipment it replaces. The difference is the saving per hour. The saving per hour multiplied by the operating hours per year is the annual saving.
The calculation should include the maintenance saving, which is harder to quantify but is real. The eliminated components do not need to be maintained, and the maintenance saving is part of the total.
What the Machine Delivers
A honeycomb paper machine that reduces electricity cost delivers output with a lower operating cost. Die-cutting speed is adjustable between 5 and 18 m/min, and die-cutting width is adjustable between 200 and 500mm. Suitable paper is ≤80gsm, and both virgin kraft paper and recycled paper work.
A compact footprint of just over 1 cubic meter, dimensions around 950x1150x1260mm and net weight near 502kg, means the machine can sit at the packing bench. A paper roll length of about 1700m, with a maximum unwind diameter of 500mm and a paper core inner diameter of 75mm, supports a long production run before the roll needs to be changed. A die that lasts about 1.0~1.3 million meters keeps the cells uniform across the entire run.
The output is biodegradable packaging and degradable packing material, a practical alternative to plastic packing materials, and it supports reuse cartons and paper recycling. A lower operating cost is what makes that output easier to sustain.
