Points for cigarette paper filtration

In addition to tobacco, cigarette paper, and filters, cigarette production also involves many other substances and materials. Tobacco additives include flavorings, enhancers, moisturizers, sugars, and ammonium compounds. Modern cigarettes are carefully designed and optimized nicotine delivery systems. In addition to tobacco, paper, and filters, their production process involves various other substances and materials. The components of a cigarette, other than tobacco, are usually referred to as "ingredients," while the term "additives" is used to refer to certain substances. The increasing competition in today's global market has created an urgent need for continuous improvement within companies. Quality plays a crucial role in business processes, as it can enhance a company's efficiency and effectiveness in global market competition. Quality control is a management function aimed at controlling the number of non-compliant products or products that do not meet specifications. Quality is one of the most important decision factors in the competition for product/service selection. Reducing the number of non-compliant products is one of the key strategies that companies must adopt to remain competitive in the global market.

Quality Indicator

Cigarette paper may seem simple, but behind every sheet lies a series of complex parameters that determine the combustion behavior, taste, and performance in different markets. With the continuous development of global regulations and brand owners' demands for greater consistency, understanding the core testing metrics is crucial for procurement teams, R&D engineers, and quality managers.

Below are the most important quality indicators commonly used in cigarette paper testing and their significance:

1.Grammage (g/m²): The Foundation of Stability

Grammage reflects the mass per unit area and serves as the benchmark for measuring the overall uniformity of the paper.

Stable grammage ensures predictable burning speed.

Fluctuations in grammage can lead to uneven burning, inconsistent ash, or varying smoke volume.

Strict control helps brands maintain sensory performance consistency across batches.

Porosity: The Driver of Combustion Behavior

2.Porosity directly impacts how oxygen flows through the paper.

High porosity accelerates combustion and affects the delivery of mainstream smoke.

Low porosity slows combustion but may increase draw resistance.

Standardized methods like CORESTA ensure comparability across markets.

3.Ignition Propensity (IP): Crucial for Fire Safety Compliance

IP testing is used to detect how easily cigarette paper will self-extinguish when unattended.

Many countries require low fire-risk (RIP) cigarettes to undergo this test.

Paper design—especially strip structures—must meet strict standards.

This is a key indicator for regulatory approval and ensuring product safety.

4.Porosity and Diffusion Ability: Impacting Taste and Chemical Composition

These parameters determine how gases and additives move through the paper.

They affect the composition of the smoke, as well as the tar and nicotine content.

They influence the stability of flavors and overall sensory characteristics.

Crucial for cigarette products using combustion modifiers or flavor technologies.

5.Tensile Strength and Mechanical Performance

Cigarette paper processing requires it to be both lightweight and durable.

High tensile strength prevents the paper from tearing during high-speed rolling.

Good elasticity ensures clean cuts and uniform rolling.

Directly impacts production efficiency and cost control.

6.Ash Characteristics: Reflection of Raw Material Quality

The color, hardness, and conical shape of the ash reflect the cleanliness of paper combustion.

Uniform ash indicates stable fiber quality and balanced chemical composition.

Irregular ash structure may suggest uneven filler distribution or moisture imbalance.

This indicator also affects the visual experience of the end consumer.

7.Moisture Content: Stability at Various Stages

Moisture content affects paper flexibility, combustion performance, and storage durability.

Too dry: The paper becomes brittle and prone to tearing.

Too wet: The paper's performance becomes unstable, potentially leading to uneven burning.

Maintaining optimal moisture ensures smooth production and stable smoking performance.

8.Chemical Composition and Additive Control

Modern cigarette papers may contain accelerants, fillers, or flavoring agents. Testing focuses on ingredients such as calcium carbonate content, citrate levels, and accelerants.

A suitable formula ensures compliance with emission regulations and achieves the desired sensory effects.

As regulatory bodies, brand owners, and consumers impose stricter scrutiny, high-precision testing has become the foundation for product safety, market access, and brand consistency.

Other Effect Factors

In cigarette paper production, several factors play a role in affecting the defects in the paper. One such factor is the dryer roll temperature, which refers to the temperature of the dryer used to dry the cigarette paper material. The temperature must be carefully controlled, as it has a direct impact on the moisture content and the dryness of the paper, ensuring it meets the required standards.

Another important element is the biocide mixture. This mixture consists of auxiliary materials added to the paper machine during production. Its main function is to eliminate any microorganisms that may be present in the paper material, while also removing any mucus-like substances that may have been absorbed by the material during production.

Lastly, the stretch ratio is a critical factor. This refers to the ratio of the speed of the engine on the paper machine. It affects the stretch properties of the cigarette paper. If the tensile force between the machines is too high, it can cause the paper to tear, which can lead to defects and inconsistencies in the final product.

By effectively managing these indicators, manufacturers can not only reduce compliance risks and enhance batch stability but also improve innovation capabilities and build trust with global partners.
