Cigarette Perforation in the Tobacco Industry

The ISO Machine-Smoking Method refers to a standardized technique used to measure the yield of constituents (like tar, nicotine, and carbon monoxide) from cigarettes during smoking.

The ISO Machine-Smoking Method refers to a standardized technique used to measure the yield of constituents (like tar, nicotine, and carbon monoxide) from cigarettes during smoking. This method is outlined by the International Organization for Standardization (ISO), specifically in ISO 4387 for cigarette tar and nicotine yield, and ISO 8454 for carbon monoxide yield.

Key aspects of the ISO Machine-Smoking Method include:

 

1. Standardized Smoking Conditions: The method specifies standardized conditions such as puff volume, puff duration, and frequency of puffs. Typically, this might be a 35ml puff of 2-second duration every 60 seconds.
   
   
2. Machine Smoking: The cigarettes are smoked by a machine which replicates human smoking behavior but under controlled and consistent conditions. This ensures that the measurements are reliable and can be compared across different cigarette brands or types.
   
   
3. Measurement of Constituents: The machine collects the smoke constituents (tar, nicotine, carbon monoxide, etc.) which are then measured. This can be done through various methods, including filters that capture particulate matter or chemical analysis of the smoke.
   
   
4. Standardization for Comparison: The results are standardized, allowing for comparison across different cigarette brands and types. This standardization is crucial for regulatory purposes and for informing consumers about the content of the cigarettes they are smoking.
   
   
5. Regulatory and Health Implications: These measurements are often used by regulatory bodies to set limits on the permissible levels of harmful constituents in cigarette smoke. They also play a role in public health by providing information about the potential harm of different cigarette types.

When it comes to inline perforation of cigarettes or HNB tobacco sticks, laser perforation is the only possible solution as traditional tool based perforation methods cannot be applied.

But also for the perforation of cigarette tipping paper during the paper converting process, laser perforation is state of the art.

This method surpasses conventional techniques by offering unparalleled precision in controlling the size, shape, and distribution of holes, all managed through software without the necessity of altering physical tools.

Such a degree of control is essential for regulating the ventilation and filtration of cigarettes. Laser perforation is characterized by its consistency and the minimal need for setup alterations.

Heat-not-burn (HNB) or heated tobacco products (THP) could often not be produced today in the same way and quality without laser perforation.

Highest speeds of up to 20,000 individual cigarettes per minute can be produced in this way.

Its non-contact approach also preserves the integrity of the tipping paper. The advanced laser machines from MLT deliver this precision at high speeds, making them particularly suitable for the perforation of cigarette tipping paper. The efficiency and precision of this technology highlight its adaptability and sophisticated capabilities.
