Specification
  • Grammage options: 40–70 gsm; the supplied grade is confirmed for the coating process.
  • Supply stage: base paper for further thermal coating; finished protective treatments are specified separately.

Thermal base paper is the starting paper for a heat-sensitive coating, supplied for further processing rather than direct thermal printing. Bofeng supports material selection and roll supply matched to the coating process and intended end use.

Where thermal base paper fits

The base carries the coating that later develops the printed image. It is selected before the thermal formulation, protective layers and finished roll or label construction are complete. Smoothness, surface sizing and absorption therefore need to suit the coating system, rather than simply resemble a finished receipt sheet.

After suitable coating and converting, such materials can serve receipt, thermal-label, medical-recording or instrument-recording applications. Image performance and storage behaviour depend on the complete finished paper and its use conditions.

Compare the base with your process

Surface and absorption

Compare smoothness, uniformity and water absorption against the coating formulation. Cobb absorption describes water uptake; it does not by itself establish ink absorption or finished thermal performance.

Appearance

Discuss whiteness, opacity and surface cleanliness. Check whether the proposed base and coat combination gives the required image contrast and reverse-side appearance.

Web handling

Match grammage, tensile strength, moisture condition and roll width to coating, drying, rewinding and slitting. Evaluate the grade on the actual line before selecting a production specification.

Prepare a material trial

  1. Send the coating system, end use, target grammage and width, plus relevant equipment and roll-handling requirements.
  2. Confirm the proposed grade and sample format. Roll supply and slit widths are agreed for the available material.
  3. Trial coating uniformity, web handling and finished image results; record the accepted specification before ordering.

Choose the right purchasing stage

If you need products ready for printing or application, browse thermal labels or thermal receipt rolls. For base-paper procurement, compare the related material pages below.
