Kraft paper is everywhere, from packaging boxes to shipping cartons. But not all kraft paper is the same. Its strength often decides whether a box will survive rough handling. To check this, manufacturers use a Ring Crush Tester, a simple yet reliable tool that measures how much pressure the paper can handle before it collapses.
An RCT tester is not just a machine sitting in a lab. It is the difference between a strong, durable box and one that tears open halfway through delivery. Paper mills and packaging companies rely on this tool to confirm whether their kraft paper sheets can handle stacking, folding, and shipping stress. Without this check, weak paper could easily fail in real-world use.
A paper strength tester is basically a referee for paper quality. It does not guess but rather relies on actual values that matter. A paper strength tester gives an exact value that shows how much load the paper can take. For kraft paper, this test is crucial because even a slight dip in strength can affect an entire production batch.
The Ring Crush Test procedure is straightforward. First, a small strip of kraft paper is cut to a standard size. This strip is then curled into a ring and placed between two flat plates inside the machine. As load is applied, the paper eventually buckles. That breaking point is recorded. The value obtained tells you the strength of the sample. Simple steps, but the data speaks volumes about the paper’s durability.
When it comes to a kraft paper quality test, RCT is one of the most trusted methods. It does not just measure paper’s ability to resist force. It also reflects how well it will perform when turned into cartons. If the kraft paper scores low, manufacturers know it will not be able to hold heavy goods or survive stacking in warehouses.
In broader packaging applications, paperboard strength measurement is equally vital. Cartons, corrugated boards, and speciality packaging all rely on accurate readings from the same testing principle. By using Ring Crush Test equipment, companies gain precise numbers that help them design packaging strong enough for their specific market needs.
So, how to test paper strength? You place the paper sample in the RCT machine, apply controlled pressure, and note the force at which it fails. That number becomes the benchmark for whether the kraft paper batch is good enough for production. It is quick, repeatable, and trusted across the industry.
Can RCT be used for corrugated boards as well as kraft paper?
Yes. With the right setup, the same equipment can measure the strength of corrugated sheets and paperboards.
Why do packaging companies prefer RCT over manual checks?
Because it gives accurate, repeatable results that remove guesswork and help ensure every carton meets strength standards.
How much does a Ring Crush Tester cost in India?
Depending on the models, features, and manufacturers, a Ring Crush Tester typically costs anywhere from INR 10K to INR 1.55L.
