As the industry pays more and more attention to sustainable development, film manufacturers are constantly improving their product technology, stepping up their strategic layout, and launching a green revolution in the packaging bag industry, an important downstream user
The general trend of green packaging bags
For many years, film manufacturers have been boasting that their products can reduce the consumption of raw materials and thus reduce costs, and have excellent quality assurance effects in the field of medicine and video packaging bags. Now, under the supervision of consumers and supervision agencies, packaging companies are constantly improving their processes 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 packaging industry to establish a green image. The film material can win out from other packaging materials because of its lighter weight and lower carbon footprint compared with glass and metal.
Factory layout is in full swing
The leading manufacturers in the field of packaging film around the world are stepping up their deployment strategies. Japanese synthetic chemistry is currently promoting the latest water-soluble film polyvinyl alcohol coating material with high gas barrier performance. This amorphous material can be used in lotion, coating and molding markets. Its biggest characteristics are: environmental protection, safety and complete degradation. As a green packaging material, the film has been recognized by environmental protection departments in Europe, America and Japan. The biological experiments show that PVA is non-toxic and will not prevent the growth and reproduction of microorganisms, and has no impact on wastewater treatment and environmental sanitation.
Further sustainable development
Some companies are taking the sustainable development strategy further, and they have developed biodegradable and renewable barrier membranes. A new film with stronger barrier is launched in the cellulose packaging bag with wood pulp as the original. One of the latest sustainable development trends in the packaging bag market is to rely on the power of nanotechnology, because developers claim that using nanotechnology will further increase the use of packaging bag materials. The latest coating launched by the American company, which leads the technology of nano synthetic barrier coating, provides a more environmentally friendly and economical choice for food packaging bags. Reduce carbon emissions and environmental impact by reducing raw materials required and using only non-toxic materials. This technology enables food companies to produce products with longer shelf life. Compared with 10-20 micron thick coating, 0.5-0.8 micron thick coating provides better oxygen barrier.
