White cardboard for cigarette pack requires high stiffness, breakage resistance, smoothness and whiteness. The paper surface is required to be flat, not allowed to have stripes, spots, bumps, warping and deformation of the generation. As the cigarette package with white cardboard. The main use of web high-speed gravure printing machine to print, so the white cardboard tension index requirements are high. Tensile strength, also known as tensile strength or tensile strength, is meant to be the maximum tension that the paper can withstand at the time of breaking, expressed in kN/m. High-speed gravure printing machine to drag the paper rolls, high-speed printing to withstand greater tension, if the phenomenon of frequent paper breaks, is bound to cause frequent stoppages, reducing work efficiency, but also increase the loss of paper.
There are two types of white cardboard for cigarette packs, one is FBB (yellow core white cardboard) and the other is SBS (white core white cardboard), both FBB and SBS can used for cigarette packs are single-sided coated white cardboard.

FBB consists of three layers of pulp, the top and bottom layers use sulfate wood pulp, and the core layer uses chemical mechanically ground wood pulp. The front side (printing side) is coated with a coating layer that is applied using two or three squeegees, while the reverse side has no coating layer. Since the middle layer uses chemically and mechanically ground wood pulp, which has a high yield to wood (85% to 90%), production costs are relatively low, and therefore the selling price of the resulting FBB cardboard is relatively low. This pulp has more long fibers and fewer fine fibers and fiber bundles, resulting in a good thickness of the finished paper, so that FBB of the same grammage is much thicker than SBS, which also usually consists of three layers of pulp, with sulphur-bleached wood pulp used for the face, core, and back layers. The front ((printing side)) is coated, and like FBB is also coated with two or three squeegees, while the reverse side has no coating layer. Since the core layer also uses bleached sulfate wood pulp, it has a higher whiteness and is therefore called white core white card. At the same time, the pulp fibers are fine, the paper is tighter, and the SBS is much thinner than the thickness of FBB of the same grammage.
Cigarette card, or white cardboard for cigarettes, is a high-quality coated white cardboard specially used for making cigarette packaging materials. This specialty paper is processed and finely manufactured through a rigorous process, and its main function is to provide cigarettes with an attractive, hygienic and protective outer packaging. As an important part of tobacco products, cigarette card not only meets the basic needs of product packaging, but also realizes the exquisite display of brand identity due to its special surface treatment and printing suitability.

Features
1. Material and quantity.
Cigarette card has a high dosage, usually above 200g/m2, which ensures sufficient thickness and strength to support and protect the cigarettes inside.
Its fiber structure is uniform and dense, made of high-quality wood pulp, and add the right amount of fillers and adhesives to ensure that the paper is both hard and has good processing performance.
2. Coating and calendering.
The calendering process makes the surface flat and smooth, enhances the stiffness and glossiness of the paper, and makes the appearance of cigarette packets more high-grade.
3. Physicochemical properties.
Cigarette card has excellent folding and tearing resistance, ensuring no breakage in high-speed automated packaging process. It has good absorption and drying properties for ink, which is favorable for fast printing and preventing ink penetration.
It meets the requirements of food safety regulations, has no odor and does not contain substances harmful to the human body, which protects the safety of consumers.
4. Environmental protection and anti-counterfeiting.
With the increasing awareness of environmental protection, modern cigarette card production tends to use renewable resources and reduce environmental pollution.
Some high-end cigarette card products also integrate anti-counterfeiting technologies, such as special coatings, colored fibers, laser patterns, etc., to cope with the increasingly serious problem of counterfeiting.

Applications
Rigid box packaging: Used in the manufacture of various brands of rigid cigarette boxes, the inner layer may also be laminated with aluminum foil and other materials to increase the barrier properties. Soft packs: Although relatively rare, cigarette cards are also used as liners or closures in some soft packs of cigarettes.
Branding:Through high-quality printing and unique design, cigarette cards help tobacco companies present their brand image and enhance market competitiveness.
Legal and regulatory requirements: With increasingly stringent regulations on tobacco packaging in various countries, cigarette cards also need to comply with the requirement that health warnings are clearly visible and difficult to tamper with.
