Green development trend of the hottest plastic fle

The green development trend of plastic flexible packaging

in recent years, China's plastic flexible packaging industry has developed rapidly, and at the same time, it has also strongly promoted the progress of food, daily chemical and pharmaceutical industries. In turn, the progress of these industries has further stimulated the market demand for plastic flexible packaging. With the continuous improvement of materials and processing technology, Gravure plastic flexible packaging is playing an increasingly important role in many fields. People can't live without shopping bags, commodity bags, garbage bags, refrigerator fresh-keeping bags, and plastic flexible packaging is also widely used in industrial products packaging, household commodity packaging, clothing packaging, and pharmaceutical packaging

entering the new century, the deepening of the world economic adjustment and the transformation of the sustainable development strategy are the general background of the world industrial reform, and also the background of the environmental change of the soft packaging industry in which plastics give full play to the characteristics of lightweight materials. With the impact of the wave of environmental protection, consumers put forward higher and higher requirements for commodity packaging. Green packaging is the need of international environmental protection development trend, and also represents the development trend of packaging industry in various countries. It is one of the important contents to improve product market competitiveness and avoid new trade barriers. Accordingly, the greening of plastic flexible packaging has also become an important development trend

connotation of green packaging

there is no completely unified definition of green packaging at present. Generally speaking, appropriate packaging that can be recycled, recycled or degraded, and does not cause public hazards to human body and environment in the whole life cycle of products is called green packaging. The most important meaning of green packaging is to protect the environment, but also has the significance of resource regeneration. Specifically, it should have the following meanings:

implement packaging reduction. Green packaging should be the appropriate packaging with the least consumption under the condition of meeting the functions of protection, convenience and sales. It usually refers to its ability to maintain its physical and mechanical properties when the temperature rises to save resources and energy, while minimizing the amount of packaging waste

it should be easy to reuse or recycle. Through repeated use, or through recycling waste, producing recycled products, burning and utilizing heat energy, composting and improving soil, the purpose of recycling can be achieved

waste can be degraded and corrupted. In order not to form permanent waste, non recyclable packaging waste should be able to decompose and decay, so as to achieve the goal of improving the soil

materials should be non-toxic and harmless to human body and organisms. Packaging materials should not contain toxic elements, halogens, heavy metals, or the content should be controlled below the relevant standards

researchers have done a lot of research on the relationship between hammer shape and impact action of composite materials. In the whole life cycle of packaging products, they should not pollute the environment and cause public hazards. That is, the whole life process of packaging products from raw material collection, material processing, product manufacturing, product use, waste recycling to final treatment should not cause public hazards to human body and environment

according to the above requirements of green packaging, the plastic flexible packaging industry is undergoing a profound green transformation in terms of processing equipment, technology and material selection
