Green packaging of cigarette products

the hot sale of high-grade cigarette products determines that its packaging will inevitably become the focus of cigarette manufacturers. Cigarette packaging is no longer shown in the old face of simple pattern and rough production, and has been reborn, giving up the traditional white card or coated paper, and using a large number of materials such as aluminum foil composite or pet coated cardboard with metallic luster and high luminosity. However, because such materials cannot be degraded, it is easy to point out the direction for the development of lightweight and green automotive materials, causing environmental pollution and inevitably bringing about environmental crisis. With the establishment of people's awareness of environmental protection, enterprises pay more and more attention to improving the environmental protection performance of cigarette packaging and printing, and choose energy-saving, low consumption, non-toxic, pollution-free, reusable, soluble, multifunctional, pollution-free packaging and printing materials. Especially in the face of the green trade barriers implemented by developed countries after China's entry into WTO and the impact of foreign low tar, high environmental protection cigarettes on the domestic market, green environmental protection has become an irresistible development trend of tobacco packaging, and it is a foregone conclusion that composite packaging materials will be gradually eliminated. The key question now is what kind of environmentally friendly materials to replace, and what ways to take to smooth the transition

environmental protection solutions for cigarette label printing

cigarette packet printing is the leader in the packaging and printing industry. Since the 1980s, the development of domestic cigarette packets has reflected a trend: coated paper -- white cardboard -- aluminized cardboard -- aluminized paper upholstery, and has been using the most cutting-edge technology and printing solutions in the domestic printing industry. At present, there are four feasible environmental protection methods for cigarette label printing: first, white card printing metal ink and large-area bronzing technology; The second is to replace composite aluminum foil paper with vacuum aluminized material; Third, white cardboard or coated paper is used to replace composite materials; Fourth, promote the application of water-based ink

1. Vacuum aluminizing material, a new favorite of green environmental protection, is a new green environmental protection material in recent years. According to statistics, at present, among the 36 key tobacco enterprises in China, 16 have used aluminized paper, 5 are conducting the machine test of aluminized paper, and 12 plan to use aluminized materials. It is not difficult to see from statistics that tobacco enterprises hold a positive attitude towards vacuum aluminizing materials. Aluminized materials have the following characteristics: (1) raw and auxiliary materials are tasteless and non-toxic, meeting the requirements of food hygiene. (2) With good smoothness, high smoothness, bright color, bright appearance and strong visual impact, it can well improve the packaging grade of products. (3) It has excellent barrier property, and has remarkable moisture-proof and antioxidant effects. (4) Excellent printing and mechanical properties, suitable for intaglio, relief, offset, flexo, silk printing, embossing, die cutting, and even embossing and other processes. (5) It has good degradability and recycling, is easy to handle and recycle, and meets the requirements of environmental protection. It is an essential packaging material for export products. As environmental protection materials, white cardboard and copper paperboard, because they do not have a sense of metallic luster, are restricted by the fact that they cannot meet the requirements of high-end cigarettes for packaging fineness in the cigarette bag market, which is seeking novelty and individuality

2. Water based inks keep up with the environmental protection situation

in order to achieve the increasingly stringent environmental management goals, printers have always been looking for new methods of solvent ink printing process. At present, the focus is to strengthen the treatment of emissions in the process of solvent ink printing. The usual practice is to use incinerators for incineration, and the other more creative is to apply the treatment system of microorganisms or bacteria that feed on VOCs. Through nearly 10 to 15 years of technological improvement, the ink system has successfully solved most of the original difficulties, such as difficult to use, ink storage, limitations of substrate, corona treatment and surface tension. The new generation of ink has changed its initial disadvantages into advantages, and gradually grew and matured. Under the premise of environment, safety and health, how to meet the best printing and post-processing adaptability of ink products and improve economic benefits is an important topic we consider

environmental protection article on "reduction and saving" of cigarette film

cigarette packaging film, referred to as cigarette film, is a kind of BOPP film. As a high-grade BOPP film, smoke film has lower heat sealing temperature, better barrier performance, high transparency, uniform thickness and other characteristics than ordinary packaging film. With the growth of cigarette consumption, cigarette factories have promoted the rapid expansion of cigarette film consumption out of the consideration of reducing the packaging cost (many cigarette factories have changed the box packaging to directly use cigarette film packaging to reduce the packaging cost). By the end of 2002, the consumption of tobacco film in China has reached about 60000 tons. BOPP film is generally unable to degrade by itself or easily corroded by bacteria due to its stable chemical structure and performance; Therefore, the cigarette film packaging is not easy to decay and decompose after being discarded, which will form permanent garbage and bring serious pollution to the environment

according to the experience of developed countries, there are three main ways to solve plastic packaging and environmental problems: reuse of plastic packaging, recycling, and development of degradable plastics. However, it is difficult to apply to smoke film products, so the main solution in China is "reduction and saving". The concept of packaging reduction is to reduce resource consumption and waste generation. Under the functional conditions of protection, convenience and sales, we should start from the source of packaging design and design appropriate packaging with the least amount of consumption, so as to reduce packaging waste. Nanjing Zhongda film (Group) Co., Ltd. first introduced this concept. The 18m BOPP cigarette film first introduced by the company not only opens up a new way for the environmental protection of cigarette film, but also has considerable advantages only in terms of material properties: (1) better optical properties and transparency, making the packaged cigarettes more high-end; (2) Because the friction coefficient, tensile strength and other mechanical properties are different from 20 μ m、21 μ m、22 μ M the thickness of the smoke film is equivalent, so the adjustment of the smoke machine is small when the smoke factory uses it; (3) Because the thickness is relatively reduced, the comprehensive cost after accounting is also reduced. At present, the thickness of smoke film in China is generally μ m. For the consideration of cost and environmental protection and the requirement of lightweight packaging materials, lighter and thinner smoke film will be the development trend in the future

development of tipping paper - healthy + environmental protection tensile strength experimental scheme: sealing tensile strength experimental scheme (small high-rise) to 110 kg (including floor reinforcement

in recent years, tipping paper has made great development and innovation in function and use. Cigarette factories have higher requirements for the printing aesthetics of tipping paper, which is not only limited to simple packaging, but also pays more attention to decoration. At the same time, with the growing voice of smoke rolling, health and environmental protection, on the one hand, perforated tipping paper has developed rapidly, especially laser perforated tipping paper. Secondly, the viscosity of hydraulic oil is increasingly popular Favored by cigarette factories, it plays an important role in the coke reduction project of the tobacco industry. On the other hand, the food hygiene requirements of tipping paper itself are also paid more and more attention by cigarette factories. Now, tipping paper uses a large number of chemicals in the printing process, such as inks, pigments, organic solvents, etc., which are very harmful to human health. Because tipping paper is in direct contact with smokers, the printing ink and coating of tipping paper must be non-toxic, meet the requirements of food hygiene, and have certain water resistance and moisture resistance

at present, the main difficulty of tipping paper environmental protection is the passing rate of ink. For example, in the past year or two, pearlescent tipping paper, which is widely used in domestic high-end cigarettes, has been welcomed by cigarette enterprises because of its elegant and soft decorative effect. However, the sampling inspection by the National Tobacco standards Center showed that a large part of the pearlescent tipping paper contained harmful substances such as aluminum and arsenic that exceeded the standard. To this end, some packaging enterprises actively seek countermeasures. For example, Merck, as an international pharmaceutical and fine chemical enterprise with leading technology, in order to meet the needs of domestic manufacturers, not only provides relevant professional advice to cigarette enterprises, but also prepares to launch a new generation of pearlescent pigments, which not only maintains green and healthy health indicators, but also facilitates the preparation of pearlescent ink, the printing of tipping paper and the performance of stronger gloss effect. In addition, for example, Minfeng Tipping Paper Co., Ltd. adheres to the use of self-produced traditional ink in the production of tipping paper, which not only reduces the impact of ink odor on the aroma of cut tobacco, but also reduces the benzene content in the ink, effectively ensuring the environmental protection of the product. In general, health and environmental protection will be the future development trend and basic requirements of tipping paper
