Description

Technical Field

[0001] This utility model relates to the field of cigarette tipping paper technology, specifically to a low-VOC-release, green and healthy cigarette tipping paper. Background Technology

[0002] With increasing global environmental awareness, VOC emissions have gradually attracted widespread attention. Due to the extensive use of organic solvents in the production process, the packaging materials industry, especially the production of inner lining paper and tipping paper for tobacco packaging, has become a significant source of VOC emissions.

[0003] Inner liner paper is primarily used to wrap cigarettes, isolating them from outside air, preserving the tobacco's aroma and providing moisture protection. This ensures the tobacco products are not affected by external environments during storage and transportation, maintaining their quality and flavor. Tipping paper, on the other hand, wraps the cigarette holder, ensuring a tight bond with the cigarette. VOCs mainly originate from the chemical solvents used in the production of inner liner paper / tipping paper. These solvents are commonly used to enhance the paper's smoothness, moisture resistance, and adhesion, and are also used in printing and coating processes to achieve desired visual effects and functional requirements. Common VOC sources in these processes include solvent-based inks, adhesives, paints, and cleaning agents.

[0004] To reduce VOC emissions from tipping paper, this invention provides a low-VOC-emission, green, and healthy cigarette tipping paper. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a low-VOC-emission, green, and healthy cigarette tipping paper.

[0006] Technical solution

[0007] A low-VOC-emission, green, and healthy cigarette tipping paper includes an upper base paper layer and a lower base paper layer; activated carbon fiber paper is disposed between the upper and lower base paper layers, and the upper surface of the activated carbon fiber paper is bonded to the upper base paper layer by an adhesive layer arranged at intervals or in a mesh; the lower surface of the activated carbon fiber paper is bonded to the lower base paper layer by a lower adhesive layer arranged at intervals or in a mesh; and a water-based ink layer is printed on the upper surface of the upper base paper layer.

[0008] Furthermore, the lower surface of the lower base paper layer is also coated with a waterproof and breathable coating.

[0009] Furthermore, a varnish layer is printed on the upper surface of the water-based ink layer.

[0010] Furthermore, the upper surface of the varnish layer is also provided with multiple hot stamping layers.

[0011] Furthermore, the upper adhesive layer and the lower adhesive layer use solvent-free adhesives.

[0012] Furthermore, the varnish layer is configured as a water-soluble resin layer.

[0013] Beneficial effects:

[0014] This invention provides a low-VOC-emission, green and healthy cigarette tipping paper. It consists of two layers of base paper with activated carbon fiber paper bonded between them. The strong adsorption capacity of the activated carbon fiber paper adsorbs VOCs, reducing emissions and making it more environmentally friendly and healthier. The water-based ink layer printed on the upper base paper layer increases water resistance and abrasion resistance. Water-based ink is preferred because it releases less VOC compared to solvent-based inks. The upper and lower adhesive layers also preferably use solvent-free adhesives, resulting in low VOC emissions. Their spaced or mesh-like arrangement facilitates the adsorption of VOCs released from the water-based ink layer by the activated carbon fiber paper. Furthermore, the varnish layer is also a water-soluble resin layer, further reducing VOC emissions. During production and after product molding, the activated carbon fiber paper effectively adsorbs and reduces VOC release. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] As attached Figure 1-3 As shown.

[0021] Example:

[0022] A low-VOC-emission green and healthy cigarette tipping paper includes an upper base paper layer 1 and a lower base paper layer 2; an activated carbon fiber paper 3 is disposed between the upper base paper layer 1 and the lower base paper layer 2, and the upper surface of the activated carbon fiber paper 3 is bonded to the upper base paper layer 1 by an upper adhesive layer 4 arranged at intervals or in a mesh; the lower surface of the activated carbon fiber paper 3 is bonded to the lower base paper layer 2 by a lower adhesive layer 5 arranged at intervals or in a mesh; and a water-based ink layer 6 is printed on the upper surface of the upper base paper layer 1.

[0023] This invention reduces VOC emissions by adhering activated carbon fiber paper 3 between the upper base paper layer 1 and the lower base paper layer 2, utilizing the activated carbon on the activated carbon fiber paper 3 to adsorb VOCs. The activated carbon fiber paper 3 is bonded to the upper and lower base paper layers by an adhesive layer. The adhesive layer is spaced or mesh-like, leaving channels between the base paper layers and the activated carbon fiber paper 3, facilitating the adsorption of VOCs that may be emitted from the water-based ink layer 6 and the base paper layers by the activated carbon fiber paper 3. Furthermore, the water-based ink layer 6 uses water-based ink, which, compared to organic solvent-based inks, uses water and a small amount of alcohol as solvents, resulting in lower volatility during printing and significantly reduced VOCs. Water-based inks are typically polyurethane or acrylate-based.

[0024] The preferred type of base paper is one with good air permeability, which is conducive to gas circulation. On the one hand, it helps the activated carbon fiber paper 3 to absorb the VOCs emitted by the water-based ink layer 6. On the other hand, it can also absorb the VOCs that may be emitted by the filter tip wrapped by the tipping paper. Furthermore, it can even absorb a small amount of some components of the smoke during smoking, such as nicotine.

[0025] It should be noted that activated carbon fiber paper 2 is prepared using either whole-paper activation or fiber blending processes. Whole-paper activation uses paper-like materials as precursors and employs physical or chemical activation to prepare activated carbon fiber paper (ACFP). The precursor raw materials can be plant fibers, synthetic fibers, or a mixture of plant and synthetic fibers. After carbonization and activation, the precursor retains its paper-like structure and possesses the relevant properties of ACFP. Fiber blending involves mixing ACF with other fibers, adding suitable dispersants and binders, and then preparing ACFP through wet forming. Because the bonding between ACF fibers is poor, it is difficult to form paper from ACF alone; therefore, it needs to be blended with other fibers for papermaking.

[0026] In one embodiment of this utility model, the lower surface of the lower base paper layer 2 is further coated with a waterproof and breathable coating 7, which can enhance the waterproof effect, prevent the structure from collapsing due to possible saliva wetting during smoking, and improve the structural stability.

[0027] Preferably, a varnish layer 8 is printed on the upper surface of the water-based ink layer 6. Applying varnish to the tipping paper can protect the printed matter and increase its gloss.

[0028] Preferably, the upper surface of the varnish layer 8 is further provided with multiple hot stamping layers to enhance anti-counterfeiting features.

[0029] Preferably, the upper adhesive layer 4 and the lower adhesive layer 5 use solvent-free adhesives. The varnish layer 8 is a water-soluble resin layer. Using water-based materials results in lower VOC emissions, leading to lower overall VOC release in the tipping paper and making it more environmentally friendly and healthier.

[0030] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
