The environmental protection of the cigarette packaging market is unstoppable
The hot sales of high-grade cigarette products have determined that the packaging will inevitably become the focus of the cigarette factory's eager pursuit. Cigarette packaging is no longer a simple design and rough old face showing people, have reborn, give up the traditional white card or coated paper, use a lot of metal luster and high-luminosity aluminum foil composite or PET coated cardboard and other materials, but because Such materials cannot be degraded and cause environmental pollution, which inevitably brings about an environmental crisis. With the establishment of environmental awareness, companies are paying more and more attention to improving the environmental performance of cigarette packaging and printing, and choosing energy-saving, low-cost, non-toxic, non-polluting, reusable, easily dissolved, multi-functional, pollution-free packaging and printing materials. In particular, in the face of the green trade barriers imposed by developed countries after the accession to the WTO and the impact of foreign low-tar and high-environment cigarettes on the domestic market, green environmental protection has become an irresistible trend for tobacco packaging, and the gradual elimination of composite packaging materials is a foregone conclusion. The key question now is to use what kind of environmentally friendly materials to replace, and what methods to use to make a smooth transition. The environmental protection solution for cigarette label printing is the leader in packaging and printing industry. From the 1980s to the present, the development of domestic cigarette packs reflects a trend: coated paper - white cardboard - aluminized cardboard - - Aluminized paper soft packs, and always use the more advanced technology and printing solutions in the domestic printing industry. At present, there are four major environmental protection methods for printing smoke labels: First, white ink and large-area gold foil printing technology; Second, vacuum aluminum material to replace composite aluminum foil; Third, use white cardboard or coated paper to replace composite Material; fourth is to promote the application of water-based ink. 1. New greed for green environmental protection - Vacuum aluminum plating material vacuum aluminum plating material is a new green environmental protection material in recent years. According to statistics, among the 36 key tobacco companies in the country, there are 16 aluminum-plated papers already in use. Five aluminum-plated paper-making machines are currently undergoing trials, and 12 aluminum-plated materials are planned to be used. It is not difficult to see from statistics that tobacco companies hold a positive attitude towards vacuum aluminum plating materials. Aluminizing materials have the following characteristics: (1) The raw and auxiliary materials are odorless, non-toxic, and meet food hygiene requirements. (2) Good finish, high smoothness, bright color, bright appearance, strong visual impact, and can well improve product packaging grade. (3) It has excellent barrier properties, moisture-proof and anti-oxidation effects. (4) excellent printing performance and mechanical properties, suitable for gravure, letterpress, offset, flexo, screen printing, embossing, die cutting, and even embossing and other processes. (5) It has good degradation recovery, is easy to handle and recycled, meets environmental protection requirements, and is an essential packaging material for export products. Similarly, white cardboard and copperplate paper, which are also environmentally friendly materials, have not been provided with a metallic luster. Therefore, in the cigarette packaging market where innovations and individuality are emphasized, they have been constrained by the inability to meet the requirements of high-end cigarettes for package exquisiteness. . 2. Water-based inks closely follow the environmental protection situation In order to achieve even more stringent environmental management goals, printers are always looking for new methods for the solvent ink printing process. The current focus is to enhance the handling of emissions in the solvent ink printing process. The usual practice is to use Incineration in incinerators, other more creative is the application of a treatment system for microorganisms or bacteria that feed on VOCS. Through nearly 10 to 15 years of technical improvements, the ink-and-wash system has successfully solved most of the original difficulties, such as difficult to use, ink storage, substrate limitations, and corona treatment and surface tension. Changing the initial disadvantage is an advantage, and it gradually grows and matures. Under the premise of environment, safety and health, how ink products meet the requirements of better printing and post-processing and improve economic efficiency are important issues for us to consider. Make an environmental protection article of the smoke film “reducing and saving†The film for cigarette packaging is referred to as the smoke film, and it is a kind of BOPP film. As a kind of high-grade BOPP film, the smoke film has lower heat-sealing temperature, better barrier property, higher transparency and uniform thickness than ordinary packaging films. With the increase in the consumption of cigarettes, cigarette factories have taken into consideration the reduction of packaging costs (many cigarette factories have changed the cartridge packaging to directly use tobacco packaging to reduce the cost of packaging), prompting the rapid expansion of the use of tobacco film. By the end of 2002, the amount of smoke film in China had reached about 60,000 tons. Because of its stable chemical structure and performance, BOPP film generally cannot be degraded by itself or easily corroded by bacteria; therefore, the smoke film will not be easily rotted and decomposed after being discarded, and will form longer garbage, which will cause serious pollution to the environment. According to the experience of developed countries, there are mainly three ways to solve plastic packaging and environmental problems: reuse of plastic packaging, recycling, and development of degradable plastics. However, it is difficult to apply on tobacco film products. Therefore, the main solution at present in China is "reduction of savings." The concept of packaging reduction is to reduce resource consumption and reduce the amount of waste generated. Under the functional conditions of protection, convenience, and sales, start from the source of packaging design, design a modest amount of packaging to reduce packaging Waste. The first to introduce this concept is Nanjing Zhongda Film & Film (Group) Co., Ltd. The first 18m BOPP cigarette film launched by the company not only opens up a new path for the environmental protection of tobacco film, but also regards material properties only. This product also has considerable advantages: (1) The optical performance is more excellent, the transparency is better, and the cigarette after packaging is more upscale; (2) The mechanical properties such as friction coefficient, stretch degree, strength and 20μm, 21μm, The thickness of the 22 μm smoke film is comparable, so the adjustment of the smoke machine is less when used in the tobacco factory; (3) Because the thickness is relatively reduced, the overall cost after accounting is also reduced. At present, the thickness of the domestic smoke film is generally 20-22 μm. For the sake of cost and environmental considerations and lighter weight requirements for packaging materials, lighter and thinner smoke films will be the trend of future development. The development of the tipping paper - health + environmental protection In recent years, the tipping paper has been greatly developed and innovated in functions and applications. The use of tipping paper in cigarette factories is not only limited to simple packaging, but also pays more attention to decorativeness and has higher requirements for the printing appearance of tipping paper. At the same time, with the growing demand for cigarette health and environmental protection, on the one hand, punched tipping paper has developed rapidly. In particular, laser-drilled cork has become more and more popular among tobacco manufacturers and has played an important role in the decoking project of the tobacco industry. On the other hand, the hygienic requirements of the tipping paper itself have also been increasingly valued by various tobacco plants. Now, in the printing process, Chinese tippler uses a large amount of chemicals, such as inks, pigments, organic solvents, etc. These raw materials are harmful to human health. As the tipping paper is in direct contact with the smoker, the printing ink and coating of the tipping paper must be non-toxic, in compliance with food hygiene requirements, and have a certain degree of water resistance and moisture resistance. At present, the main difficulty in the environmental protection work of tipping paper is the issue of ink qualification rate. For example, in the last year or two, pearlescent tipping papers commonly used on domestic high-grade cigarettes are popular among cigarette companies for their elegant and soft style. However, spot checks conducted by the National Tobacco Standards Center indicated that a large part of the pearlescent tipping paper contained excessive levels of harmful substances such as aluminum and arsenic. To this end, some packaging companies actively seek solutions. For example, as a leading international pharmaceutical and fine chemical company, Merck, in order to meet the needs of domestic manufacturers, not only provides related professional consultations to cigarette companies, but also prepares to launch a new generation of pearlescent pigments to maintain green and healthy health indicators. It is more convenient for the preparation of pearlescent inks, the printing of tipping papers, and the performance of stronger gloss effects. In addition, if Minfeng Shuisong Paper Co., Ltd. insists on using self-produced traditional ink in the production of tipping paper, it not only reduces the effect of ink odor on the aroma of tobacco, but also reduces the amount of benzene contained in the ink, effectively ensuring the environmental protection of the product. Sex. On the whole, health and environmental protection will be the development trend and basic requirements of the tipping paper in the future.
