The domestic PE protective film industry has made a lot of progress in reducing waste pollution. With the gradual implementation of domestic environmental protection regulations, greater progress will be made this year. To adapt to this, its greening has become one of the important development trends. There is currently no fully unified definition of green packaging. Appropriate packaging that can be recycled, reused or degraded, and does not cause pollution to the human body and the environment during the entire life cycle of the product is called green packaging.
The most important meaning of green packaging is to protect the environment, but also has the meaning of resource regeneration. The use of heat-sealable stretch film and varnish can significantly reduce the amount of material, and it has been widely used in cold drink ice cream packaging. The protective film has successfully reduced the thickness of the entire packaging film through the use of high-strength metallocene polyolefins, and the phenomenon of excessive packaging is gradually reducing. Co-extrusion composite technology and equipment applications are becoming more and more popular, solving the problem of precise control of each layer. The problem of film thickness. The thickness of the high-priced barrier layer can be controlled very thin, and the freshness preservation performance can be doubled or even dozens of times improved. my country's PE protective film industry has been developing rapidly, and it has also strongly promoted the progress of food, daily chemical and pharmaceutical industries. The progress of these industries in turn has further stimulated market demand.
With the impact of the wave of environmental protection, consumers have put forward higher and higher requirements for commodity packaging. Green packaging is the need of the international environmental protection development trend. The protective film also represents the development trend of the packaging industry in various countries. It is one of the important contents to improve the product market competitiveness and avoid new trade barriers.
