Measuring cigarette paper diffusivity: ensuring safety and quality introduction

Why measure diffusivity in cigarette paper? 

The diffusivity of cigarette paper plays a critical role in the safety and quality of tobacco products. By analyzing the movement of gases through the paper during combustion, manufacturers can ensure their products comply with safety regulations and provide an optimal smoking experience.  

Introduction to the tobacco industry through CRM77 

Since the 1990s, the fire hazard posed by cigarettes has been a major concern for the tobacco industry. To reduce the number of accidental fires, many countries have enacted regulations requiring the production of self-extinguishing cigarettes. These cigarettes use Low Ignition Propensity (LIP) paper, which is specifically designed to stop burning when left unattended. Compliance with these safety standards is monitored using the Coresta Recommended Method 77 (CRM77), which serves as the benchmark for diffusivity measurement.
