With the development of the rolling economy and the rapid rise of the packaging industry, packaging bag waste has also increased. If not processed in time, it will seriously pollute the environment and form a vicious and controllable trend. At present, the recycling, processing and reuse of packaging waste has become a top priority for environmental protection in various countries and is also the primary measure to control global environmental pollution.
Packaging bag waste is about 16 million tons, accounting for 25% of the volume of urban waste. If things go on like this, it will lead to serious environmental pollution and a huge waste of resources. The economic losses caused by solid waste in our country every year and the value of usable but unused waste resources reach 30 billion yuan.

with plasticpackaging bagFor example, my country produces about 3 million tons of plastic packaging products every year. The recycling and reuse of its waste can save a lot of energy and resources. If plastic waste is used to make plastic parts and packaging containers, compared with using pure resin to make plastic parts and packaging containers, 85~96% of the energy required can be saved. If incineration is used to recycle plastic waste, energy can be saved, but Compared with the recycling and reuse method, the latter can save more energy. For example: the combustion value of 45.4 kg of polyethylene is 19,000 joules, but recycling can save 38,000 joules of energy.
   packaging bagWaste recycling is generally divided into two categories: material recycling and thermal energy recovery. At present, the recycling of domestic packaging waste is mainly based on material recycling.
Material recycling technology is to regenerate the sorted (according to packaging material type) packaging bag waste into new similar materials using corresponding processing technology. As far as recycling technology is concerned, various types of packaging bag waste can generally be recycled, but the economics of their recycled materials are quite different. Among them, the economics of recycling paper, glass and metal are relatively unreasonable, while plastics are not ideal.

Thermal energy recovery is to put mixed flammable packaging waste into an incinerator for combustion, and use the heat energy generated during the combustion process as energy for power generation and heating. Generally, there is no need to clean mixed materials before heat energy recovery.packaging bagThe waste is strictly sorted, and the result of the recycling process is that the volume and weight of the solid waste are greatly reduced. It is a convenient method of packaging waste disposal. However, it is worth mentioning that the flue gas generated during the recycling process must be treated with reliable technical measures to prevent secondary pollution of the atmosphere.

Current status of recycling and treatment of plastic packaging bag waste Types and uses of plastic packaging materials The use of plastic packaging materials in my country accounts for about 26% of the entire plastic production. There are many varieties of plastic packaging, many types of molding, and a variety of excellent properties. For example, they are divided into various materials such as normal temperature resistance, low temperature resistance, range temperature resistance, stretch resistance, pressure resistance, and shockproof. In packaging It is widely used in the industry, whether it is food (solid or liquid), industrial products, groceries, chemicals, stationery, etc. Currently, the most widely used plastic packaging materials are: polyethylene, polypropylene, polyethylene, polyvinylon vinyl acetate copolymer, etc. Plastic finished products are available in the form of film fibers and rigid molding materials. The film can be made into various plastic packaging bags, the fiber can be woven into handbags or larger woven bags, and the rigid molding materials can be made into various plastic barrels, plastic bottles and plastic packaging boxes, turnover boxes, calcium plastic boxes, etc.
