A thermal paper jumbo roll is a large, uncut roll of thermal paper used primarily as the raw material for producing smaller rolls (like POS receipt rolls, ATM paper, labels, tickets, or fax rolls).
Here’s a breakdown of its key aspects:
Thermal Paper:
- Coating: Has a heat-sensitive coating applied to one side.
- Printing Mechanism: When exposed to heat from a thermal print head (like in cash registers, credit card terminals, or label printers), the coating turns black in the heated areas, creating text, barcodes, or images. No ink, toner, or ribbon is required.
- Types:
- Direct Thermal: Common for receipts, tickets, shipping labels (short-term use). Image can fade over time with heat, light, or chemical exposure.
- Thermal Transfer: Requires a ribbon (donor film). The thermal head melts the ribbon’s ink onto the paper. Used for more durable labels and barcodes requiring longer lifespan/chemical resistance. (Note: While the paper itself is often still thermal paper, the printing mechanism is different. Jumbo rolls can be used for both applications, but the paper coating might differ for thermal transfer).
Jumbo Roll:
- Size: Very large dimensions (the “parent roll”). Typical widths range from 3.5 inches (90mm) up to 8.5 inches (216mm) or more. Diameters can be 18 inches (450mm) to 30 inches (760mm) or larger, weighing hundreds of pounds/kilos.
- Purpose: Manufactured at paper mills or converters in bulk. These rolls are then slit (cut lengthwise) into narrower widths and rewound onto smaller cores to create the rolls used in end-user devices.
- Core: Has a sturdy inner core (usually heavy-duty cardboard or plastic, 3″ or 6″ diameter is common for jumbos) for mounting on large converting/slitting machinery.
Key Specifications When Ordering:
- Width: The full width of the jumbo roll (e.g., 90mm, 110mm, 215mm).
- Outer Diameter (O.D.): The finished roll size (e.g., 18″, 20″, 25″, 30″).
- Core Size (I.D.): Inner diameter of the core (e.g., 3″, 6″).
- Paper Weight/Thickness: Measured in microns (µm) or grams per square meter (gsm). Common weights: 48gsm, 52gsm, 55gsm, 60gsm. Thicker paper is generally more durable.
- Type: Direct Thermal or Thermal Transfer (specify if needed).
- Coating: Standard, Top-Coated (for better fade/chemical resistance), BPA-Free/BPS-Free (increasingly important for receipts handled frequently).
- Color: Usually white paper with black print, but other base colors (like yellow for security paper) are possible.
- Length: Sometimes specified, but often determined by the O.D. and weight/thickness.
Primary Applications (After Slitting):
- Point-of-Sale (POS) receipts
- Credit/Debit card terminal receipts
- ATM transaction receipts
- Fax machine rolls
- Lottery tickets
- Parking tickets
- Shipping labels (direct thermal or thermal transfer)
- Barcode labels (thermal transfer for durability)
- Medical recording paper
- Gas pump receipts
Purchasing Considerations:
- Minimum Order Quantity (MOQ): Suppliers often have high MOQs due to the large size and bulk nature (e.g., multiple rolls per pallet).
- Supplier: Typically purchased from paper mills, large paper converters, or specialized thermal paper distributors.
- Quality: Crucial for consistent print quality, avoiding jams, and preventing premature fading. Reputable suppliers are key.
- Certifications: Look for BPA/BPS-Free certifications if required for your end-use (especially receipts).
- Storage: Store in a cool, dry, dark place. Avoid heat, humidity, direct sunlight, solvents, and plasticizers (like PVC wrap) which can cause fading or print defects (“ghosting”).
In simple terms: A thermal paper jumbo roll is the giant, factory-sized roll of special heat-sensitive paper that gets cut down into all the smaller receipt and label rolls you see used in stores, restaurants, and warehouses every day.
