As the industry pays more and more attention to sustainable development, film manufacturers are Continuously improve product technology, step up strategic layout, and initiate a green revolution in the packaging industry, an important downstream user. The general trend of green packaging For many years, film manufacturers have been claiming that their products can reduce the consumption of raw materials and thus reduce costs, and have excellent quality preservation effects in the fields of medicine and food packaging. Nowadays, under the urging of consumers and regulatory agencies, packaging companies continue to improve the craftsmanship of stationery shops in order to make more contributions to sustainable development. Some companies believe that the use of advanced film packaging technology will become an important part of the stationery shop packaging industry to establish a green image. The film material can outperform other packaging materials because it has a lighter weight and has a lower carbon footprint than glass and metal. Wout Luyton, business development manager of Eval, a supplier of ethylene/vinyl alcohol copolymer (EVOH) resin, said that in addition to consuming more raw materials, food and beverages packaged in metal or glass need to be consumed during transportation. More energy, which means that boxed wine that uses a diaphragm to ensure that the beverage does not deteriorate has a lower carbon footprint than traditional glass bottled wine. Dow's special packaging and film business division market development manager Julia Schlenz (Julia Schlenz) agreed. She said: Well-known manufacturers are trying to abandon fragile and expensive packaging materials, especially in the field of food packaging. The industry is looking for ways to streamline packaging across the board, which means that packaging that is softer than rigid materials will stand out. The layout of manufacturers is in full swing. Globally leading manufacturers in the field of packaging films are stepping up the deployment of new strategies. Toray announced last year that it plans to establish Toray Film Europe in Europe to produce biaxially oriented polypropylene (BOPP) high-barrier metallized films. BOPP metallized film is mainly used for vacuum metallization, radiation, anti-counterfeiting substrate and food packaging, with excellent heat sealing strength and inkless printing effect. The company plans to build a 20,000-ton/year thin film production plant and a 22,000-ton/year metallization plant with a total investment of about 4 million euros. The new plant will be put into operation in April next year. Nippon Synthetic Chemicals is currently promoting its latest water-soluble film polyvinyl alcohol (PVOH) coating material with high gas barrier properties. This amorphous material can be used in emulsion, coating and molding markets. Its biggest features are: environmental protection, safety, thorough degradation, and the final products of degradation are carbon dioxide and water. As a green packaging material, the film has been approved by the environmental protection department in Europe, America and Japan. Biological tests have shown that polyvinyl alcohol is neither toxic, nor does it prevent the growth and reproduction of microorganisms, and has no effect on wastewater treatment and environmental sanitation. On May 1 this year, China Hong Kong Evergreen Environmental Protection Industry Co., Ltd. signed an investment agreement with the Xiangcheng District Government of Xiangfan City, Hubei. It will invest US$99 million to build a fully biodegradable packaging film production line with an annual output of 60,000 tons. The first phase investment is US$33 million. Sustainable development goes further Some companies are taking a sustainable development strategy to go further. They have developed biodegradable and renewable barrier films. Innovia is one of them. The stationery shop recently launched a new film with stronger barrier properties on the basis of NATureFlex, a cellulose packaging film made from wood pulp. Inno company spokesperson Zena Bergmann (Zena Bergmann) said that users choose NatureFlex because it provides the same excellent properties as metalized films, while being biodegradable, and can even be fermented into fertilizer under certain conditions. , Which can effectively reduce packaging waste in the environment. One of the latest sustainable development trends in the packaging film market is to rely on the power of nanotechnology, because developers claim that the use of nanotechnology will further reduce the use of packaging materials. The latest NanolokPTADV-7 coating from InMat, a leading nano-synthetic barrier coating technology in the United States, provides a more environmentally friendly and economical choice for food packaging. By reducing the required raw materials and using only non-hazardous materials, stationery stores can reduce carbon emissions and environmental impact. This technology enables food companies to produce products with a longer shelf life. Compared with 10-20 micron thick EVOH coating, 0.5-0.8 micron thick NanolokPTADV-7 coating provides better oxygen barrier properties. Company principal Harris Goldberg said: The unique feature of this technology is that our coating can be applied at low thickness and high speed through standard coil coating equipment, while achieving high barrier properties and low cost. . This provides end users with a more environmentally friendly, low-cost, high-barrier packaging film.
