On Aug. 8, 2016, in order to speed up the reduction of VOCs (VOCs) in key industries and promote industrial green development, the Ministry of Industry and Ministry of Finance jointly issued the "Action Plan for Reducing Volatile Organic Compounds in Key Industries". According to the "plan", by 2018, the industrial sector VOCs emissions than in 2015, more than 3.3 million tons, which requires low (no) VOCs adhesive products in 2018 to reach more than 85%, China's adhesive industry will face reshuffle.
Industry changes: solvent-based slow pace, low (no) VOCs type outbreak growth
Flexible packaging industry application of adhesives, from its chemical composition point of view, mainly solvent adhesives, water-based adhesives, solvent-free adhesives and other categories. Solvent adhesive as a high-performance products have contributed to the vigorous development of the flexible packaging industry, and achieved great economic benefits. However, VOCs in the production of solvent adhesives are highly polluting and may pollute the environment. Their trace amounts of solvent remain in the substrate, and may cause odor in the packaging, causing potential food safety problems.
In contrast, water-based adhesives, solvent-free adhesives are almost no VOCs emissions, more green. At present in Europe and the United States market, environmentally friendly adhesives have accounted for a considerable proportion, and in China, due to industry development and historical reasons, solvent adhesives are still the main position, water and solvent-free market share of less than 20%.
The current domestic economy is facing high growth from high-speed growth in the new normal, the internal structure of the optimization and quality of the upgrade to become a top priority. The relevant state ministries issued a document, only to 2 years to reduce the adjustment of VOCs displacement time, and in the policy, regulations, funds and other supporting the introduction of many powerful measures, fully demonstrated the country in the adhesive industry to implement green and sustainable development Determined that the whole industry chain, it is also a can not be ignored vane: solvent-based adhesives will be partially replaced, low-VOC adhesives will usher in explosive growth.
The majority of consumers on this policy is even clapped. In recent years, with the continuous improvement of China's total economic output and the rapid rise of the middle class, they not only consume more ability, but also higher quality requirements. In terms of food, not only stay in the taste, the consumer groups also pay more attention to the raw materials from the product, processing and packaging to ensure the safety and quality of each link.
At the same time, the penetration of the world's convenient culture for the country's flexible packaging industry has brought a broader market space. According to authoritative packaging market research firm SmithersPira reported that in 2015 the global consumer flexible packaging market size of about 91.7 billion US dollars, 2020 is expected to reach 114 billion US dollars, an average annual increase of 4.4%. A huge industry, will lead to the whole community more, more detailed consumer concerns. Therefore, the use of adhesives for flexible packaging, especially food packaging, as an important addition factor, must ensure absolute safety and green, zero negative impact on food in order to win the basic trust of consumers, food brands to provide strong support.
As a global leader in adhesive technology, Dow has a variety of adhesive products and innovative solutions, product platform security, reliable, environmentally friendly, superior performance, application is mature, and continue to market demand. In China, Dow is actively pursuing its environmental strategy by actively embarking on the environmental strategy of the Chinese government, pushing its leading solvent-free and water-based adhesive innovation technology into a challenge to provide Chinese customers with both green and practical flexible packaging solutions.
Dow Shuang Bi: water-based, solvent-free adhesives and integrated solutions
Dow in the Chinese market, the main push of the two types of adhesive products in addition to the common advantages of green, but also have their own characteristics. Among them, the water-based adhesive is Dow's housekeeping products, Dow's first developed for the world's food packaging, one-component water-based adhesives, and for the application of two-component two-component water-based adhesive. In terms of its technological innovation capability, Dow has an undoubted industry-leading position in this field.
Compared with traditional solvent adhesives, water-based adhesives are first environmentally friendly. In the solvent-based adhesive production and application process, the solvent drying will be discharged into the atmosphere, causing pollution. But the water glue is the carrier of water, emissions to the atmosphere is only water, the health of the surrounding workers without harm; Second, the application cost of water glue more competitive and more efficient. Solvent glue in the process of sizing too fast, the temperature is too high, there is the potential danger of burning, explosion, so the operating speed of solvent in China is generally controlled at 150 meters per minute to 200 meters. The water glue because there is no such risk, the composite speed than the solvent glue can be more than 20% higher. In addition, the water-based glue and solvent glue can be used in the equipment, if you have to reduce the VOCs displacement, and do not want to eliminate the original dry complex machine, the user can choose Dow's water-based glue to use, from this point of view, Adhesives will be the use of solvent-based adhesives for the majority of manufacturers to reduce the pressure of many replacement equipment.
Water-based adhesives in the substrate adaptability also has outstanding advantages. It has a good affinity for aluminum foil and is suitable for BOPP (PET) / VMCPP, BOPP (PET) / MPET and other applications for inflatable food packaging applications for food hygiene and hygiene. Among them, one-component water-based adhesives are often used in instant noodles, bread, pies, pastries, puffed food, candy and other food packaging, two-component water-based adhesives have a wider range of product adaptability, To a higher composite performance and resistance to media properties. Such as applied to snack packaging in the water-based adhesive can provide a higher composite strength, to ensure that the original flavor of the product is not affected, but also reduce the overall solvent residue, to ensure food safety and health.
Dow is also accelerating the pace of innovation, its new generation of polyurethane water-based glue will be in 2016 for the market, the advent of this new technology will break the current water-based glue in the field of flexible packaging applications bottlenecks, Covering the common function and function of the product range, with better resistance to cooking and chemical resistance of the media, for the majority of the urgent transformation of Chinese customers to bring green and functional combination of the perfect solution.
At the same time, Dow's solvent-free adhesive technology is also far ahead, and in the Chinese market has been more widely recognized. Dow has been developing solvent-free adhesives since 1970. It is the world's first solvent-free adhesive company that meets film cooking applications and meets aluminum foil cooking applications. It has the world's first high-temperature cooking solvent-free adhesive, non-barrier type Solvent glue and other patents.
Solvent-free adhesives have developed faster in the market in recent years because, by comparison, it is the most environmentally friendly, lowest cost and most efficient. Because there is no solvent, so there is no emissions, the production process and the health of workers without injury, no solvent costs, and the composite speed can be open to 300 to 400 meters per minute, if the equipment to force, or even open to 400 meters per minute to 500 M, the unit time efficiency greatly improved, but also for the enterprise to greatly save production costs, during which no solvent needs to be dry and collected, curing cycle quickly, can be achieved within 90 minutes cutting. At the same time product performance, wide range of applications, has a prominent low cost advantage.
Solvent-free adhesives are suitable for low-grade applications. Its single component solventless adhesive for a variety of transparent or metallized film and aluminum foil on the paper or cardboard composite packaging, the main agent NCO groups such as MOR-FREETMELM415A and 205A are mainly applied to the high-performance products, composite packaging , Including suitable for film / film, film / foil, film / aluminum composite, high efficiency, excellent product performance, the product of primary aromatic amine can also be quickly eliminated, so as to ensure safety and health, in line with domestic and foreign food Safety indicators.
At present, the rapid development of the Asian region, especially the Chinese market, makes solvent-free adhesives need more detailed market to adapt to the client's diversified and personalized application requirements. Based on this, the Dow Adhesive will fully enhance the solvent-free product performance in common functions, such as higher compound strength and longer product availability (disk life), while providing the latest friction coefficient stable solvent-free solution, Thus achieving a high follow-up end product packaging efficiency, to help enhance the competitiveness of customers in the functional market.
Dow's water-based adhesives and solvent-free adhesives are excellent in safety standards, technical maturity, and application levels. All products sold in China are certified by the US Food and Drug Administration. At present in the general function and some functional level, water-based glue and solvent-free glue has been completely replace the solvent glue.
The most intimate is that Dow also offers two solutions for composite applications of adhesives, to meet the needs of the actual market segmentation to the maximum. Such as potato chips packaging, it seems a thin layer, but the actual three-tier packaging structure, which requires two composite. Dow's overall plan is: the first composite water glue, because the plastic glue in the aluminum structure has an advantage, the composite was fast, and cooked too fast, after a few hours can be carried out under the next process. The second compound is solvent-free adhesive. This combination of programs, can maximize the efficiency of operation, greatly reduce production costs, shorten delivery time, reduce the backlog of funds to meet customer requirements for rapid delivery, but also to protect the food packaging and the final product of environmental protection and safety.
Symbiosis: Dow 's concept of full - value chain cooperation
In order to better serve the development of China's flexible packaging industry, Dow in addition to continuing the advanced technology research and development, but also deep plowing, is committed to the whole value chain cooperation, in a variety of cooperation to promote industry innovation and market development.
Dow and Nordmeccanica of Italy have reached a global innovation and business development agreement. Nordisk is the world's leading supplier of complex equipment, its solvent-free composite machine in the Chinese market share of about 60%. Dow and Nordisk have developed a new solvent-free technology that greatly improves the rate of solvent-free ripening and increases productivity. Using this new technology, Dow's solvent-free adhesive in the Nordisk equipment to complete the composite, 90 minutes to cut, one day to complete the bag and food packaging. The ripening process has changed from a few days to less than one day, and this is undoubtedly a huge and disruptive to the improvement of production efficiency.
Dow and the vast number of food industry brands to carry out extensive and in-depth cooperation and achieve common development. For example, Want Want is one of the largest water-based adhesives consumers in the Chinese market, and most of the adhesives used are from Dow. Dow recently held a special seminar in Shanghai for Wangwang, Wangwang's food product structure and performance requirements of a comprehensive analysis and recommendations in improving environmental protection, moisture resistance and other aspects of the Want Want Group to provide a more efficient and sustainable Packaging solutions, but also for the Want Want team training courses arranged in order to help Chinese customers in this way to achieve smooth implementation of VOCs emission reduction, accelerate the realization of green development goals.
Not only that, Dow to "symbiotic win-win" concept extended to the whole society. Dow has released the "2025 Sustainability Goals", which is driven by Dow's strong innovation, global business, and employee efforts through the integration of public policy solutions, technological innovation and value chain innovation, energy efficiency, etc. Sustainable development and recycling economy. Believe that Dow's greener, safer, more efficient products, symbiotic win-win concept, leading the Chinese low-VOCs viscose market and promote the rapid development of China's flexible packaging industry, but also help China to create a sustainable development The beautiful picture.
