Some Facts about Cigarette Paper

Cigarette Paper

The primary purpose of cigarette paper is just to maintain the tobacco in the form of a pipe, from which smoke can be inhaled. Cigarette production is a speedy procedure which sets particular requirements on the technical qualities of the cigarette paper.  The composition of the cigarette paper also influences the burning processes that take place in the course of both smoldering and smoking.  This, on the other hand, can considerably impact the smoke chemical make up and other ability features of the cigarette.

The main component of cigarette paper is cellulose fiber, extracted generally from wood pulp. It generally includes approximately 20% to 30% calcium carbonate and often more than 2% of burn ingredients - salts such as potassium that impacts the burn process of the paper. The blend of the filler and the burn ingredients provides a white paper ash right after the paper is burnt. 

Fiber handling in the course of paper production allows the paper its natural porosity - affecting the burn level of the cigarette and therefore both the mainstream and side stream smoke produces. Additionally, burn ingredients that enhance swifter burning may lead to reduced mainstream ‘tar’ yields of the cigarette by decreasing the puff quantity.  ‘Tar’ yield per smoke is not enhanced by burn ingredients.

Air penetrability and normal porosity are the two main factors chosen to explain and define the porous composition of cigarette paper. Penetrability is calculated making use of a worldwide identified standard, while porosity is generally calculated by a method known as mercury porosimetry. Porosity is considerably more tightly linked with the expansion ability of the cigarette paper than air penetrability. This is because the process that handles air-flow via pores of diverse dimensions. 

Laser perforation is often used in order to increase the penetrability of the cigarette paper and to provide enhanced air dilution while puffing. As opposed to genuine penetrability, laser perforation has a little impact on oxygen expansion through the paper and as a result does not modify the burn level of the cigarette paper. The trend becomes more complicated as both the porosity and penetrability of the paper alters when the paper is being heated up during smoking process.
