4.0-4.5Microns BOPET TTR (Thermal Transfer Ribbons) basic film series for carbon
What is BOPET TTR Film?
BOPET stands for Biaxially Oriented Polyethylene Terephthalate — a type of polyester (PET) film that has been stretched in two directions (machine direction and transverse direction) to enhance its mechanical and thermal properties. When used as the base film for Thermal Transfer Ribbons (TTR), it serves as the substrate onto which ink/wax/resin coatings are applied for thermal printing.
Polyester film is the base material of choice for Thermal Transfer Ribbons (TTR). The thermal transfer printing applications are segmented into "standard TTR," Dye Diffusion Thermal Transfer (D2T2), and thermal stencil. For standard TTR, the main thickness is 4.5 microns.
Key Specifications
Available thickness options for BOPET thermal transfer film include 4.4, 4.5, 4.55, 4.6, 4.8, 5.0, 5.7, and 6.0 µm.
Common widths include 500, 600, 910, 980, 1010, 1200, and 1500 mm, and roll lengths range from 15,000 to 37,000 meters. Ec21

The combination of mechanical strength and thermal resistance makes polyester film unique for the TTR market. Key properties include dimensional stability, ease of processing/coating, heat resistance, and tear resistance. M-petfilm
BOPET thermal transfer ribbons have excellent stability features in shrinkage and thickness consistency, good heat resistance, and are easy to process in thermal transfer applications. Boppfilmsales
Additionally, compared to transitional capacitor-grade films previously used in TTR applications, purpose-built BOPET for TTR shows greatly improved heat stability, stripping resistance, cleanliness, and surface adaptability to coated solvents, meeting the various performance requirements needed for high-speed TTR coating.
Applications
TTR films are used in a variety of applications including bar code printers, fax printers, portable printers, ticketing machines, monochrome ribbons, and color ribbons. M-petfilm
They are also used as the base for hot stamping films and silver metallized films in specialty printing.
Why 4.5 Microns?
The 4.5-micron gauge represents the industry sweet spot for standard TTR:
Thin enough to transfer heat quickly and efficiently from the print head to the ink layer
Strong enough to resist tearing during high-speed processing and printing
Dimensionally stable to prevent warping, shrinking, or stretching during coating and ribbon slitting
Certain applications use 5.7-micron film, and some specialty products are based on film thicknesses below 4.5 microns — but 4.5 µm is the dominant commercial standard.
Typical Roll Dimensions (Commercial Supply)
Roll lengths available include 15,000; 16,300; 17,000; 18,500; 20,000; 24,000; 36,000; 40,000; 44,000; and up to 55,000 meters. Common widths include 1,200; 1,290; 1,350; 1,400; 1,500; and 1,560 mm. Longer rolls reduce the number of joints in downstream processing, which is critical for high-speed ribbon coating lines.
Summary
BOPET TTR Film at 4.5 microns is a highly engineered, ultra-thin polyester film designed specifically as the backbone of thermal transfer printing ribbons. It balances mechanical durability, thermal conductivity, dimensional stability, and surface compatibility — making it the global standard base film for barcode, label, fax, and specialty thermal printing industries.
