The development trend of POF shrink film

The development trend of POF shrink film Do you know the development trend of POF shrink film? The author will explain to you. At present, packaging waste is increasing day by day, recycling technology has been initially mature, and the state proposes to treat solid waste in the direction of reduction, harmlessness, and recycling. Investment in packaging waste recycling is not only feasible, but also Promote the development of the packaging industry. On the one hand, this is in line with the country’s sustainable development strategy. The strengthening of environmental protection has solved the worries about the development of the packaging industry and opened up new economic growth points for it; on the other hand, marching into the environmental protection industry can develop cheap packaging industry The source of raw materials reduces the original production cost and has the dual benefits of economy and ecology. With the increase in the amount of packaging waste, waste treatment costs continue to rise, and it is a general trend to increase the recycling of packaging waste. However, in the process of rapid development of packaging production, my country still has a large gap with developed countries in terms of waste management, disposal and recycling. First of all, the recycling of packaging materials has obvious economic and ecological benefits. According to relevant experts, although there are many types of packaging waste, they can be basically divided into four categories: paper products, plastic products, glass products and metal products according to the materials of packaging products. Packaging wastes are mostly renewable resources. Second, the continuous growth of packaging waste output provides sufficient production resources for recycling. From the statistics of the total output of the packaging industry in the country, the current paper packaging products are about 8.35 million tons, the plastic packaging products are about 2.44 million tons, the glass packaging products are about 4.44 million tons, and the metal packaging products are about 1.61 million tons. At the same time, these products are increasing at a rate ranging from 12.5% u200bu200bto 30% every year. Research data shows that 1 ton of waste paper can be recycled 0.8 tons of new paper or 0.83 tons of cardboard; 1 ton of waste plastic can be recycled 0.75 tons of diesel or 0.6 tons of unleaded gasoline. It can be seen that there is no need to worry about the issue of recycling'raw materials'. Third, the treatment technology of packaging waste is becoming more and more mature, and the treated packaging waste has broad uses, and the market prospect is promising. After the discarded snack boxes are recovered, they can be mixed with soil or other substrates through crushing and harmless treatments for soilless or semi-soil cultivation. Waste plastic oilification technology uses high-performance catalysts to 'depolymerize' high-density polyethylene or polypropylene plastics, which can produce diesel and gasoline that meet national standards, with an oil yield of over 75%. If necessary equipment is installed, liquefied gas and carbon black can also be recovered. By changing the catalyst, chemical products such as toluene, xylene and pure benzene can be produced. In addition, waste plastics (including PE, PP, PVC, PS) and filling mixtures (including a variety of urban and rural wastes such as activated carbon waste residue, crushed animal and plant waste, weathered coal, humic acid and other powders) are used to form a fertilizer coating. The cost of membrane is only about 300 yuan/ton more than ordinary compound fertilizer. This is an environmental protection project that turns'white pollution' into'green fertilizer', which can absorb a large amount of packaging waste.
