Hengli Kanghui Thermal Transfer Ribbon/TTR/ Polyester/ BOPET Base Film/ 3.9/4.5 Micron

A thermal transfer ribbon (TTR) is a consumable component used in thermal transfer printing, a common method for creating high-quality prints on various materials. The ribbon consists of several layers, and it is often made from BOPET film. BOPET stands for biaxially oriented polyethylene terephthalate, which is a type of polyester film that has been stretched in both the machine and transverse directions. This stretching process enhances the film's mechanical and thermal properties, making it suitable for a variety of applications, including thermal transfer ribbons. Here's an introduction to the components and features of a typical thermal transfer ribbon by  BOPET film:   Thickness Tensile strength (MD/TD) Break elongation (MD/TD) Modulus(MD/TD) Transmittance Shrinkage(MD/TD) Haze Wetting tension 3.9-4.5μm ≥240MPa/≥220MPa ≥80%/≥80% ≥4000MPa/≥4000MPa >88% ≤2.0%/≤0.2% 5.7% ≥54mN/m *The price is for reference only please contact us for details in person for a quotation!
