Thermal Paper Jumbo Rolls: A Practical Buying Guide for Paper Converters

Savvy resellers and vendors realize that POS thermal paper rolls are a small but steady business. So, instead of importing small finished thermal rolls, they purchase jumbo rolls in bulk and cut them in their factories. In this case, they will require thermal jumbo rolls.

However, with so many different brands and types of thermal jumbo rolls on the market, how can you be sure you’re buying the right product and maximize your business ROI? This comprehensive guide will walk you through everything you need to know about thermal jumbo rolls. By the time you’re done reading, you will be more equipped with the knowledge to choose the perfect materials for your business. Let’s get started.

1. What Are Thermal Jumbo Rolls?

Thermal paper jumbo rolls, also called big thermal rolls, master rolls, slitter rolls, or giant rolls, are large-format heat-sensitive paper used by converters to produce small finished rolls like POS cashier rolls, ATM paper, ticket paper, and label rolls.

In brief, converters make profits by processing jumbo rolls into small usable products through converting, laminating, and printing.

2. Consider Jumbo Roll Size

The first step when buying thermal jumbo rolls is to determine the correct dimensions. Key considerations include the jumbo roll width, outer diameter (OD), core inner diameter (ID), and maximum roll weight. These specifications must be compatible with your slitting and rewinding machine as well as suitable for producing the finished POS roll sizes you plan to make.

Thermal jumbo roll dimensions are usually described as width x length x core. For example:

• A typical thermal jumbo roll size is 401mm x 6000m x 76mm, where the width is 401mm, the length is 6000m, and the core (inside the paper roll) is 76mm (3″).
• Another example is 790mm x 12000m x 76mm, where the width is 790mm, the length is 12000m, and the core size is 76mm.

We have explained why jumbo roll width is crucial in our article on how thermal paper rolls are produced. To produce 80mm cashier rolls, you need a jumbo roll width divisible by 79mm, such as 558mm or 636mm. (We make the roll width 79mm, rather than 80mm, because of the waste during the slitting process, and to make sure the paper roll feeds smoothly in the 80mm thermal printers.) To produce 57mm cashier rolls, you must use a jumbo roll with a width divisible by 56mm (again, 1mm less), like 565mm or 844mm.

In general,

• Jumbo Roll Width: The common jumbo roll widths used to produce 80mm thermal rolls are 401mm, 558mm, 636mm, 716mm, and 795mm, etc. And the common jumbo roll widths used to produce 57mm thermal rolls are 565mm, 790mm, and 844mm, etc.
• Jumbo Roll Length: A jumbo roll’s length can range from 5000m to 15000m, depending on the paper manufacturer. Most jumbo roll manufacturers, like Panda Paper Roll, can produce any paper length to meet the customer’s requirements.
• Core: Thermal jumbo rolls usually come with a standard 3-inch (76mm) core.

Below is a list of common jumbo roll dimensions for slitting into 57mm and 80mm cashier rolls.

3. Inspect the Paper GSM

GSM, or grams per square meter, is a unit of measurement that indicates the weight of paper. It is used to describe the density of the paper. It is the most important factor determining the weight, thickness, and even price of thermal paper.

Thermal paper GSM usually ranges from 48 gsm to 80 gsm. The common GSM and thickness of thermal paper are:

• 48 gsm (52 – 56 um)
• 55 gsm (60 – 64 um)
• 60 gsm (75 – 80 um)
• 65 gsm (83 – 86 um)
• 70 gsm (90 – 95 um)

Should you choose thick or thin paper? There is no one-size-fits-all solution because customers have different requirements. You should select the appropriate paper that best suits the printing application and customer’s needs.

• Low GSM (48-55): Typically used in lightweight receipt paper where cost and speed are more important, such as 80mm x 80m 48gsm thermal paper for POS receipt printers.
• Medium GSM (55-70): Commonly used for general-purpose receipts and tickets that require a balance between durability and cost, such as 80mm x 80mm 65gsm paper for general POS cash registers.
• High GSM (70-80): Used for applications requiring more robust paper, such as direct thermal labels, longer-lasting tickets, and documents requiring better print quality.

4. Evaluate the Paper Quality

Quality thermal paper is crucial for ensuring your customers have a positive experience with your product. It directly impacts how smoothly the roll feeds through a printer, how well images print on the receipt, and how long it lasts before it fades. Our previous blog post covered how to evaluate the quality of thermal paper, which you should consider.

Here is a quick takeaway for you:

• Paper sensibility refers to a thermal paper’s ability to print sharp images without smudging.
• Smoothness is also crucial because it affects how well the paper feeds through the printer.
• Meanwhile, the paper’s whiteness impacts the contrast of the printed image, while coating helps to protect against ink smearing.
• Archivability refers to a paper’s ability to withstand fading over time.
• Top-coated paper adds a protective layer on the outermost surface, making it resistant to water, oil, and even scratches.
• BPA- or BPS- free thermal paper is becoming increasingly important to comply with stricter policies and regulations.

Always ask the manufacturer for the technical datasheet and lab certification when you order jumbo rolls.

5. Check the Jumbo Roll Price

Price is always an important consideration when you buy thermal paper, especially when you buy in bulk. The price can vary significantly from one supplier to the next. In addition, thermal paper prices can fluctuate with global market conditions.

Thermal paper jumbo rolls are usually sold per ton or per square meter. To give you an overview of how to calculate and compare prices, there’s a formula for the conversion.

• For example, for 55gsm thermal paper, the price is $1,500 per ton, which can also be calculated as $0.0825 per square meter (0.055 × 1,500 ÷ 1,000).
• For 65gsm thermal paper, the price is $1,400 per ton, which is $0.091 per square meter (0.065 × 1,400 ÷ 1,000).
• The formula is: Price per square meter = GSM × Price per ton ÷ 1,000. Conversely, if we know the price per square meter, we can also convert it to the price per ton.

6. Choose A Premium Thermal Paper Mill

Thermal paper production technology is dominated by only a few large thermal paper mills worldwide, across Germany, Japan, America, South Korea, China, etc. Always source thermal paper jumbo rolls from reputable paper mills to ensure better performance in the final POS receipt products, because premium thermal paper brands tend to have mature coating technology and full supply-chain control. Their paper provides sharper printing images, a smooth surface, less waste, and increased production efficiency.

We recommend you compare the products of Koehler Paper, Hansol Paper, Mitsubishi Paper, and Oji Paper, to name a few. Remember, a premium paper brand often stands for reliable quality, which can give you peace of mind and help you sell your products to end customers worry-free.

Thermal Jumbo Rolls Frequently Asked Questions

1. How long does thermal paper last?
In general, thermal paper can last at least 3 years from the manufacturing date if it is stored properly before printing. But please understand that the lifespan of thermal paper can vary depending on storage conditions and environmental factors. Exposure to light, heat, and humidity can degrade the chemical coating on the paper, leading to a loss of image quality.
2. How do I store my thermal paper jumbo rolls?
You should store your thermal paper jumbo rolls in a cool, dry warehouse away from direct sunlight or heat sources. Ideally, the humidity of the storage room should be between 45 percent to 60 percent, and the temperature should be about 25 degrees Celsius. We also recommend storing your jumbo rolls vertically to help prevent them from warping or distortion. You can also follow the thermal paper manufacturer’s storage instructions or guidelines to maximize the lifespan of the paper.
3. What is the difference between thermal paper and normal paper?
Normal paper, such as the A4 paper you use in the office, is suitable for various printing methods like inkjet and laser. It works by absorbing the ink or toner powder from the cartridge onto the paper to form the print. Thermal paper, however, is coated with a heat-sensitive chemical layer; it reacts to heat from the printhead to generate the print. In this process, it doesn’t need ink or toner. Thermal paper is commonly used for receipts and labels, but it is prone to fading over time when exposed to heat and light.
