Recycling of composite materials - reduce the impact of packaging materials on the environment

formulate the development plan of green packaging materials. The situation of green business is as follows: the development of industrial packaging materials involves many high and new technologies. Industrial developed countries have studied fully biodegradable plastics for several years, but so far there are not many real industrialized products, which involves many problems of experimental research and industrial production. Green business this device has carried out more than 100 technological transformation and development of packaging materials based on the process of BP's VCC experimental device. Jinan testing machine factory has modified the shelf stability experiment, loading stability when the movable parts of the non fixed cabinet are opened, and other double knife manual broaching machines are not only a matter of the packaging industry, but also need the cooperation of the whole industry; Not only industrial enterprises, but also scientific research institutes and colleges and universities

clean production processes are 'less waste' and 'no waste' processes. A closed production cycle should be established to recycle the materials that volatilize, precipitate or escape, emit, drip or leak during the production process; As the recycling of raw materials, a closed production process from raw materials input to waste recycling is established to minimize the external discharge of waste, which not only improves the utilization rate of resources, but also fundamentally eliminates the generation of 'three wastes', so that the production of packaging industry does not cause harm to the environment

the biggest disadvantage of composite materials is that it is difficult to recover, and it is difficult to separate. If composite materials are mixed into a single material during recovery, the recovery quality of a single material will be damaged. For example, aluminum paper plastic composite materials are mixed into a single cardboard recycling material, which will destroy its beating performance; If the composite film is mixed into the single plastic film, the recycled products will also be scrapped

in fact, the environmental pollution caused by paper, plastic, metal, glass and other packaging materials mainly used in the market in the production process is far greater than that caused by waste. Therefore, in order to make packaging materials have 'green' performance in the whole life cycle, it is necessary to carry out cleaner production
