In recent years, China's plastic flexible packaging industry has been rapidly developed, but also strongly promoted the progress of food, daily chemical and pharmaceutical industries. These industry advances in turn 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 areas. People's lives can not be separated from shopping bags, merchandise bags, garbage bags, refrigerator storage bags, industrial packaging, Household commodity packaging, clothing packaging, and pharmaceutical packaging also use plastic flexible packaging.
In the new century, the world economic restructuring continues to deepen and the transformation of sustainable development strategies is the overall background of the world's industrial transformation, and it is also the background of the environmental changes in the plastic flexible packaging industry. With the impact of the environmental protection wave, consumers are increasingly demanding the packaging of goods. Green packaging is a requirement for the development of international environmental protection. It also represents the development trend of packaging industry in various countries, and is one of the important contents of improving product market competitiveness and avoiding new trade barriers. Corresponding to this, the greenization of plastic flexible packaging has also become an important development trend.
The connotation of green packaging
There is not a completely unified definition of green packaging. In general, moderate packaging that can be reused, reused, or degraded, and that does not pose a hazard to the human body or the environment throughout the product's lifecycle is called green packaging. The most important meaning of green packaging is to protect the environment, but it also has the significance of resource regeneration. Specifically, it should have the following meanings:
Implement packaging reduction. The green packaging should be the least amount of appropriate packaging under the conditions of protection, convenience, and sales. To save resources and energy while minimizing the amount of packaging waste.
It should be easy to reuse or easy to recycle. Through repeated use, or through the recovery of waste, production of recycled products, incineration and heat energy, and composting to improve the soil and other measures to achieve the purpose of recycling.
Waste can degrade. In order not to form permanent waste, non-recyclable packaging waste should be able to decompose, and then achieve the purpose of improving the soil.
Materials should be non-toxic and harmless to humans and organisms. The packaging material should not contain toxic elements, halogens, heavy metals, or the content should be controlled below the relevant standards.
In the entire life cycle of packaging products, pollution should not be caused by environmental pollution. That is to say, the packaging products shall not cause harm to the human body and the environment from the collection of raw materials, material processing, manufacturing of products, use of products, recycling of wastes, and the whole process of the final disposal.
According to the above requirements of the green packaging, the plastic flexible packaging industry is undergoing a profound transformation in terms of green, whether it is processing equipment and processes or material selection.
