The plug wrap paper is a specialized paper used in the manufacturing of filter cigarettes. It plays a crucial role in wrapping and shaping the filter material into the desired long filter shape. The plug wrap paper is a key component in the production of filter cigarettes, and it has several important applications and characteristics.

Applications of Plug Wrap Paper:

1. Filter Encapsulation: Plug wrap paper is primarily used to wrap the filter material, which is typically made of materials like acetate fiber. This wrapping process creates the filter plug, an integral part of filter cigarettes.
2. Smoke Dilution: In the late 1960s, the use of plug wrap paper underwent significant changes. Cigarette manufacturers started using highly permeable plug wrap paper in combination with perforated tipping paper to dilute the smoke as it passes through the filter. This technological advancement was aimed at reducing the delivery of harmful components, such as tar and carbon monoxide, to the smoker.
3. Quality Enhancement: The properties of plug wrap paper are essential for the overall quality of the cigarette. The paper must have high tensile strength, good air permeability, proper formation, and bonding capabilities to ensure the filter’s structural integrity and performance.

Types of Plug Wrap Paper: There are generally three types of plug wrap paper:

1. Non-Porous Plug Wrap Paper: This type of paper is less permeable and is often used in traditional filter cigarettes.
2. Porous Plug Wrap Paper: Highly porous plug wrap paper is used in combination with laser-perforated tipping paper to reduce the tar content in cigarettes, improving their overall health profile.
3. Barrier Plug Wrap Paper: This type of plug wrap paper may incorporate a barrier layer to further control the release of specific components.

Key Points in Production: The production of plug wrap paper involves several key considerations, including:

• Tensile Strength: The paper must possess high tensile strength in both the longitudinal and lateral directions to withstand the manufacturing process and maintain filter integrity.
• Air Permeability: Proper air permeability is necessary for regulating the smoke dilution process and controlling the delivery of harmful constituents.
• Formation: Good formation ensures that the paper wraps uniformly around the filter material, contributing to the structural integrity of the filter.
• Bonding: Effective bonding between the plug wrap paper and the filter material is crucial to prevent unraveling or separation during the cigarette manufacturing process.

Raw Materials: The raw materials used in plug wrap paper production typically include softwood pulp, bleached hardwood pulp, and hardwood pulp. These pulps are often sourced from countries such as Canada, Brazil, and Russia.

Packaging: The plug wrap paper products are typically cut to size and wound onto bobbins according to specific requirements for shipment.

In summary, plug wrap paper is a specialized material with crucial applications in the production of filter cigarettes. It is designed to wrap and shape the filter material, contributing to the reduction of harmful components in cigarette smoke. Various types of plug wrap paper are available, each with specific characteristics, and its production involves careful attention to key properties and the use of specific raw materials.
