How Many Small Finished Rolls You Can Make from One Jumbo Roll?
Last Updated: May 26th, 20233.8 min read
Everyone knows the small thermal paper rolls are made from jumbo rolls with the slitting and rewinding machine. But do you know how many small rolls you can make from one jumbo roll? If you know the answer, you will have a better understanding of how thermal roll prices are formed. In this article, we will answer this question for you!
First, we’ll assume you are familiar with the following:
If you understand these basics, we can go on to the question.
Thermal jumbo rolls
1. How many 80mm x 80mm thermal rolls can you make from one jumbo roll?
80mm x 80mm thermal roll is the most popular size among the various paper roll sizes. We ship about 10-15 containers of 80mm x 80mm thermal rolls to the worldwide market every month. It is compatible with any receipt printer that requires an 80mm thermal roll, such as Epson, NCR, Uniwell, Sharp, etc. We usually use the 558mm x 6000m jumbo rolls to produce the 80mm x 80mm thermal rolls. So the question is: how many 80mm x 80mm thermal rolls can you make from one 558mm x 6000m jumbo roll?
The 558mm jumbo roll is cut into 7 rows
The above picture shows how the blades cut the jumbo rolls into 7 rows (558mm/79mm=7). Also, we know the 80mm x 80mm thermal roll’s length is around 60m, so there can be 100 rolls (6000m/60m=100 rolls) cut out per row. Hence, 700 rolls (7 rows x 100 rolls per row = 700) can be made from one jumbo roll.
There is still an easier way to figure out this question. From this article, we can know one 80mm x 80mm thermal roll weighs 0.29kg (0.08m x 60m x 0.06kg/m² =0.29kg). Then we know that one jumbo roll weighs 200kg (0.558mm x 6000m x 0.06kg/m² = 200kg). So as we can easily see, we can get about 690 rolls (200kg/0.29kg=690) from one jumbo roll. This method allows a little tolerance in calculating since there is some paper wasted in the manufacturing process. In any case, this is just another method for your reference.
2. How many 57mm x 40mm thermal rolls can you make from one jumbo roll?
57mm x 40mm Thermal paper roll is another popular size. Many customers will combine this size with 80mm x 80mm thermal paper when they make a purchase from us. It is widely used in credit cards, mobile POS, and many other applications. We usually use a 565mm x 6000m jumbo roll to produce the 57mm x 40mm paper size. So the question is: how many 57mm x 40mm thermal rolls can we make from one 565mm x 6000m jumbo roll?
The 565mm jumbo roll is cut into 10 rows
With the same method, we can see the blades can cut the jumbo rolls into 10 rows (565mm/56m=10). As the 57mm x 40mm thermal roll’s length is 12m, there can be 500 rolls (6000m/12m= 500) out per row. Hence we can get 5,000 rolls (10 rows x 500 rolls/row=5,000rolls) from one 565mm x 6000m jumbo roll.
3. Another method to verify our calculation
We can also use the “weight method” to verify our calculations. The weight of single 57mm x 40mm thermal roll is 0.04kg (0.56m x 12m x 0.06kg/m²=0.04kg), and the weight of the jumbo roll is 200kg (0.565m x 6000m x 0.06kg/m²= 200kg), so we can easily get there can be 5,000 rolls (200kg/0.04kg= 5,000 rolls) come out from one jumbo roll.
Understanding this question is important because you will know how many jumbo rolls you must procure when your customer orders. This knowledge also lets you monitor your production rate. For example, if you know your jumbo roll should produce 5,000 rolls and your employee only produces 4900 rolls, your production rate is 98%.
Now, do you clearly understand these two questions?
How many 80mm x 70mm thermal rolls can come from one 636mm x 5800m jumbo roll?
How many 57mm x 50mm thermal rolls can come from one 565mm x 6000m jumbo roll?
