Dow water-based, solvent-free adhesive technology strong into China's soft packaging market.

The Ministry of Industry and Information Technology and the Ministry of Finance jointly released the Action Plan for Volatile Organic Reduction in Key Industries. According to the Plan, China's adhesive industry will face a reshuffle by 2018, when VOCs emissions in the industrial sector are cut by more than 3.3 million tons from 2015. Solvent-based pace slows down, low (no) VOC type or will explode into growth.
Dow Double: Water-based, solvent-free adhesives and integrated solutions
Dow's two types of adhesive products in the Chinese market, in addition to the common advantages of green environmental protection, but also have their own characteristics. Among them, water-based adhesive is Dow's watcher products, Dow world first developed for food packaging single-group water-based adhesives, and for medium-functional applications of two-part water-based adhesives. In terms of its technological innovation capabilities, Dow has an unquestionable industry leader in this field.
than conventional solvent adhesives, water-based adhesives are first and foremost very environmentally friendly. In the production and application of solvent-based adhesives, solvent drying is discharged into the atmosphere, causing contamination. But the carrier of hydrogel is water, discharge into the atmosphere is only water, no harm to the health of the surrounding operators; If the solvent glue in the process of geling too fast, too high temperature, there is a potential risk of combustion, explosion, so solvent glue in China's operating speed is generally controlled at 150 meters to 200 meters per minute. Because there is no such risk, the compound speed can be more than 20% higher than that of solvent glue. In addition, water-based glue and solvent glue in the equipment can be universal, if you must reduce the VOC displacement, and do not want to phase out the original dry re-machine, the user can completely choose Dow hydrogel to use, from this point of view, the choice of water-based adhesives will use solvent-based adhesives for the vast number of manufacturers to reduce the pressure of many replacement equipment.
water-based adhesives also have outstanding advantages in the adaptability of substrates. It has good affinity with aluminum coating, suitable for BOPP (PET)/VMCPP, BOPP (PET)/MPET and other structural and inflatable food packaging applications compound, for food packaging more hygienic and safe. Among them, single-component water-based adhesives are often suitable for instant noodles, bread, pies, pastries, puffed food, candy and other food packaging, two-component water-based adhesives have a wider range of product adaptability, can bring users higher composite performance and media resistance. Water-based adhesives used in snack packaging can provide higher compound strength, ensure that the original flavor of the product is not affected, but also reduce the overall solvent residue, to ensure the safety and health of food.
In order to continuously break through the application limitations of existing water glue, Dow is also accelerating the pace of innovation, its new generation of polyurethane water-based glue will be market-oriented in 2016, the advent of this new technology will break the current water-based glue in the field of soft packaging application bottlenecks, covering the general function and medium function of the product application range, with better cooking and chemical media resistance, for the vast number of urgent transformation of Chinese customers to bring green environmental protection and functional perfect combination of solutions.
the same time, Dow's solvent-free adhesive technology is also far ahead, and in the Chinese market has been more and more widely recognized. Dow has been developing solvent-free adhesives since 1970, is the world's first to develop a film cooking application and to meet aluminum foil cooking applications of solvent-free adhesive enterprises, with the world's first high-temperature cooking solvent-free adhesive, non-barrier-free solvent-free adhesive and other patents.
solvent-free adhesives have grown faster on the market in recent years because they are the most environmentally friendly, cost-effective and efficient by comparison. Because there is no solvent, so there is no emissions, no harm to the production process and workers' health, no solvent costs, and the compound speed can be opened to 300 to 400 meters per minute, if the equipment to force, can even open to 400 meters to 500 meters per minute, unit time efficiency greatly improved, but also for the enterprise to greatly save production costs, there is no solvent need to dry and collect, curing cycle is very fast, can achieve 90 minutes of cutting. At the same time, excellent product performance, a wide range of applications, with outstanding low application cost advantages.
solvent-free adhesive is mainly suitable for low- and medium-functional applications. Its single-component solvent-free adhesives are suitable for a variety of transparent or metalized films and aluminum foil-to-paper composite packaging, while the main agent NCO groups such as MOR-FREETMELM 415A and 205A are mainly suitable for medium High-functional product composite packaging, including suitable for film / membrane, film / aluminum foil, film / aluminum coating composite, compound efficiency is very high, excellent product performance, products in the primary aromatic amine can also be quickly eliminated, to ensure safety and hygiene, in line with domestic and foreign food safety indicators.
, the rapid development of Asia, especially the Chinese market, makes solvent-free adhesives need a more segmented market to meet the diverse and personalized application needs of clients. Based on this, Dow adhesives will comprehensively improve the performance of solvent-free products in general functions, such as higher compound strength and longer product life (disk life), while providing the latest stable coefficient of friction solvent-free solutions, resulting in a high subsequent end product packaging efficiency, to help enhance the competitiveness of customers in the mid-functional market.
Dow's hydrogels and solvent-free adhesives excel in safety standards, technical maturity, and application levels, and all products sold in China are FDA certified. At present, at the general function and some functional levels, water-based glue and solvent-free glue has been completely replaced by solvent glue.
, Dow also offers solutions for two adhesive composite applications to maximize the segmentation needs of the real market. For example, the packaging of potato chips, it looks like a thin layer, but the actual three-layer packaging structure, which requires two composite. Dow suggested the overall solution is: the first compound water glue, because the glue in the aluminum coating structure has advantages, compounding fast, and ripening fast, a few hours later can be carried out the next process. The second compound uses solvent-free glue. This combination of solutions can maximize operational efficiency, greatly reduce production costs, shorten delivery time, reduce the backlog of funds to meet customer requirements for fast delivery, while ensuring food packaging links and the final product of environmental protection and safety.
Symbiotic win-win: Dow's concept of full value chain cooperation
In order to better serve the development of China's soft packaging industry, Dow in addition to adhere to continuous advanced technology research and development, but also deep cultivation, committed to the whole value chain cooperation, in a variety of diversified cooperation to promote industry innovation and market development.
Dow and Nordmeccanica of Italy have reached global innovation and business development agreements. Nordmec is the world's leading supplier of composite equipment, its solvent-free composite machine in the Chinese market share of about 60%. Dow and Nordmec have jointly developed the latest solvent-free technology that greatly improves solvent-free ripening and productivity. Using this new technology, Dow's solvent-free glue is compounded on Nordmec's equipment and can be sliced in 90 minutes, completing bag making and food packaging in one day. The process of ripening has changed from a few days to less than one day, which is undoubtedly huge and disruptive to the increase in productivity.
Dow also and the vast number of food industry brands to carry out extensive and in-depth cooperation to achieve common development. Wangwang Group, for example, is one of the largest consumers of water-usable adhesives in the Chinese market, and most of the adhesives it uses come from Dow. Taoshi recently held a special seminar for Wangwang in Shanghai, Wangwang's food product structure and performance requirements for a comprehensive analysis and recommendations, in improving environmental protection, moisture-proof performance for Wangwang Group to provide a more efficient and sustainable packaging solutions, but also for the Wangwang team to arrange packaging training courses, in order to help Chinese customers successfully achieve VOC emission reduction, accelerate the realization of green development goals.
, Dow has extended the concept of "symbiotic win-win" to the whole society. Dow has released the 2025 Sustainable Development Goals to promote sustainable development and a circular economy through the integration of public policy solutions, technological innovation and value chain innovation, and energy conservation, building on Dow's strong innovation capabilities, global business layout, and employee efforts. Believe that Dow greener, safer, more efficient products, symbiotic win-win concept, in leading China's low VOC adhesive market and promote the rapid development of China's soft packaging industry, but also to help China to create a sustainable development of a beautiful picture.
