Inventory turnover is the ratio of the cost of goods sold to the average inventory value. A higher turnover means the operation is using its inventory efficiently. A lower turnover means the operation is holding more inventory than it needs.
Cushioning material is part of the inventory, and it affects the turnover ratio. A bulk order of finished cushioning increases the average inventory value, which lowers the turnover ratio. The effect is small for a large operation and significant for a small one.
How Finished Cushioning Sits in Inventory
Finished cushioning sits in inventory from the day it is delivered to the day it is used. The period is weeks or months, depending on the order frequency and the consumption rate. During that period, the material is part of the average inventory value.
The material also degrades in storage. Bubble wrap compresses, air pillows lose pressure, and foam inserts deform. The material that degrades is still counted in the inventory value until it is written off, which means the inventory value is overstated.
How Paper Rolls Change the Inventory
Paper rolls change the inventory because they are a raw material rather than a finished good. Raw materials are counted at a lower value than finished goods, and they are consumed more predictably. 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.
The paper rolls also take up less space. The same protection capacity requires less storage volume, which means the operation can hold a larger buffer in the same space, or hold the same buffer in less space.
Why the Turnover Ratio Improves
The turnover ratio improves because the average inventory value drops. The operation holds fewer SKUs, and each SKU has a lower value. The reduction in value is the reduction in the numerator of the turnover ratio.
The ratio also improves because the inventory is consumed more predictably. The paper rolls are converted to cushioning at the rate the packing line consumes it, which means the inventory does not sit idle for months.
How to Measure the Effect
The practical way to measure the effect is to track the average inventory value for cushioning material before and after installation. The value is the sum of the material on hand, valued at the purchase price. The difference is the reduction in inventory value.
A die that lasts about 1.0~1.3 million meters keeps the cells uniform across the entire run. The uniform cells mean the consumption is predictable, which means the inventory can be held at a lower level.
What the Machine Delivers
A honeycomb paper machine that improves inventory turnover delivers output with a smaller inventory footprint. 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.
Power requirements are modest: 1.5kW total power at AC220V/50HZ, with no compressor, heating element, or adhesive system. 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. 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 higher turnover ratio is what makes that output easier to finance.
