Discussion on the application and development trend of cigarette packaging materials (Continued)

2 Cigarette trademark paper and trademark printing

cigarette trademark is the symbol added by cigarette manufacturers to cigarette products. Trademark design should not only be beautiful and generous, but also be closely related to product brand building and marketing. Now many large enterprises consider the design of product trademarks comprehensively from the height of enterprise strategic decision-making, so as to achieve the best advertising effect. Many cigarette labels have unique designs and distinctive personalities, which play a good role in transmitting product information

the trademark paper of cigarettes mainly includes offset paper, cast coated paper and white cardboard. The paper is required to be fine and firm, with good inking rate of color printing, soft and unbroken pleats during packaging, and color printing does not deink, which can maintain the neat and beautiful appearance of the small package

anti counterfeiting and environmental protection are the focus of cigarette packaging and printing. Cigarette trademark materials mainly include laser holographic transfer paper, anti-counterfeiting laser aluminum cardboard, BOPP laser rainbow cardboard, pet laser rainbow cardboard and aluminum foil composite cardboard. Among them, except that laser holographic transfer paper and anti-counterfeiting laser aluminum paperboard are environmental protection materials, the latter three kinds of paper have poor environmental protection performance because plastic film and aluminum foil cannot be degraded

laser holographic transfer paper is made of holographic plastic film first, and then transferred to the paper. It has the functions of anti-counterfeiting, decoration and environmental protection. Its physical properties are the same as that of ordinary paper. It can be recycled and degraded. Its price is slightly higher than that of ordinary aluminum sprayed gold and silver cardboard. It is a recommended environmental protection product in developed countries. Its comprehensive use effect is good and meets the requirements of industrialized production in the packaging industry

anti counterfeiting laser aluminized paper (card) is a gold and silver card produced by transfer aluminizing technology. Its flatness, smoothness and printing are moderately good, and it is not easy to deink. Then it has anti-counterfeiting function through laser embossing process. Due to the extremely thin aluminum film sprayed, all waste paper can be recycled, so it is internationally recognized as "green packaging"

BOPP laser rainbow paperboard and pet laser rainbow paperboard stick the laser film on the paper with glue. At present, the laser rainbow aluminum coating is mainly imported; The latter two processes are the same as the production process of ordinary composite paperboard. Generally, the non aluminized surface of laser rainbow film is compounded with paper, and the aluminized surface is used as the printing surface. The performance difference between the two kinds of paper is that the tensile strength, paper stiffness, printability and other indicators of BOPP laser rainbow paperboard are not as good as pet laser rainbow paperboard. Because BOPP laser rainbow paperboard is thicker, and its stiffness is not as good as pet laser rainbow paperboard, which is unfavorable to high-speed tobacco packaging machine

cigarette trademark printing mainly includes offset printing, flexo printing, gravure printing and other methods. Among them, gravure printing inks use a large number of low boiling point (high volatility) organic compounds as solvents (solvent components account for 50%), which leads to a large number of harmful exhaust gases in gravure printing production and prominent environmental pollution. Organic compounds (VOC) and polycyclic aromatic solvents (PCA) in offset printing ink solvents will produce organic compound gas pollution, and fountain solution and cleaning agent waste liquid will also cause pollution. At present, low toxic alcohol soluble ink and non-toxic water-based ink are widely used in flexographic printing, so flexographic printing has good environmental protection performance, which should be advocated in cigarette label printing. In addition, white cardboard is used on the strip box and printed on the outer plastic film, which is also very popular abroad. In the future, it should be a trend to use a single white cardboard for the production of cigarette packets and hard boxes in China

3. Card paper

card paper is used in the cigarette hard box packaging to support the cigarette box, commonly known as cigarette tongue. The material is the same as the white card paper used for trademark printing. The most common is that a layer of gold or silver pigment is coated on the surface of the white card paper, which is called gold card or silver card. In addition, there are aluminized cardboard, laser cardboard, holographic cardboard and laminated cardboard and other materials

2 resistance spot welding

in addition to the general performance of cigarette box packaging, with the improvement of consumers' requirements for cigarette smoking taste, the taste of paperboard must be strictly controlled. No odor, low gram weight, high stiffness, economy and environmental protection are the development trend of paperboard

at present, many foreign cigarette packaging material manufacturers have invested a lot of money and manpower to research and develop thinner paperboard. Developing and producing thinner cigarette packaging materials with single material and stable performance is the key for cigarette packaging to meet the requirements of environmental protection

4. Cigarette lining paper

cigarette lining paper is used in the small box packaging of cigarettes that have been successfully gasified and fed for one time. Its main function is to prevent moisture, fragrance and mildew. The materials include rolled aluminum foil paper, aluminized paper, asphalt moisture-proof paper and general lining paper. The lining material should be soft and easy to fold without cracking

calendered aluminum foil paper is calendered from paper base, adhesive and aluminum foil, which has high barrier and corrosion resistance to light, air and water. When the temperature changes rapidly, the material will not deform. It is a widely used cigarette lining paper at present. Direct aluminized paper is a new technology product that has developed rapidly abroad in recent years. Its advantage is that it has strong metal texture and bright color. It is suitable for the processing of various printing machines, embossing machines and high-speed die-cutting machines. It is mainly used to carry out relevant testing experiments on large tonnage metal and non-metal mechanical materials such as steel bars, cement, concrete, castings, etc. direct aluminized products, with their good environmental protection performance and mature processing equipment and technology, have become popular in the European and American markets in recent 3-5 years, and began to enter the domestic market. Direct aluminized paper (mainly imported) has been widely used in the domestic tobacco and alcohol industry. In 2003, vacuum aluminized lining paper also entered the cigarette inner packaging market in China. By 2006, 30% of the inner packaging of cigarette boxes in China will use direct aluminized paper

vacuum aluminized paper is produced by direct spraying or transfer method. The aluminum film is thin and uniform, with good optical effect, good shielding and reflection of light and ultraviolet rays, and can effectively prevent the aging effect of light on the contents of cut tobacco. It is an environmental protection product, easy to handle and recycle, and can be completely incinerated into ash

aluminized lining paper is widely used abroad. For example, British American tobacco company widely uses vacuum aluminized paper as the lining material of its famous cigarette packets. According to statistics, at present, 70% of British cigarettes and 50 German cigarettes use aluminized paper as cigarette lining paper. Foreign countries have done a lot of work in developing new cigarette lining paper with phase transition functional high molecular materials and devices. For example, an Indonesian company has introduced a metal plated material to replace the original composite aluminum foil paper, which is coated with 0.04 μ M metal, the thickness is much lower than the traditional calendered aluminum foil paper

second, the urgency and necessity of cigarette green packaging

at present, the degree of environmental protection of cigarette products in western countries is very high, while the domestic requirements for cigarette packaging materials still remain on physical indicators such as quantitative, thickness, tensile strength, elongation, moisture permeability and so on, and environmental protection issues have not been considered. With the social attention to environmental protection issues, it is necessary for the tobacco industry to carry out research and Discussion on the environmental protection performance of cigarette packaging materials, guide cigarette factories to choose packaging materials conducive to environmental protection, and reduce environmental pollution. The production and application of "green packaging" products will be the focus of the development of the tobacco industry in the next few years

cigarette packaging materials are not only a problem faced by the cigarette industry, but also involve environmental protection, chemical, biological, electronic and other technical fields, as well as the requirements and constraints of policies and regulations. Increasing research efforts in all aspects, formulating reasonable laws and regulations, and producing and using cigarette packaging materials that are more economical, affordable and meet environmental protection requirements are conducive to the sustainable development of the cigarette industry
