Natural materials have great potential for green packaging

green packaging is also called environment-friendly packaging, which generally means that the packaging design can not only ensure the performance of goods, but also meet the requirements of environmental protection and resource regeneration. Green packaging conforms to the strategy of sustainable development, so it is gradually becoming the mainstream direction of packaging design. Recently, food packaging safety problems have occurred frequently. Therefore, the green packaging branch of the Chinese society of Environmental Sciences has issued an industry initiative of self-discipline to all packaging enterprises, hoping that packaging enterprises will consciously abide by national laws and regulations, consciously increase scientific research and innovation, and devote themselves to studying and discussing how to provide more environmentally friendly and healthy green packaging for the public through various effective ways and means. The materials of green packaging mainly come from the vast nature, so natural materials have great potential in the field of green packaging

■ paper packaging

because the main component of paper packaging is natural plant cellulose, which is decomposed by microorganisms, it will decay quickly in nature, will not pollute the environment, reduce the cost of processing packaging waste, and the raw materials of paper packaging are rich and easy to obtain, so paper packaging has become the current international popular "green packaging". Paper packaging is widely used to replace metal cans to hold all kinds of liquid drinks, food, milk, etc. for example, the aseptic fresh-keeping carton packaging of "Tetra Pak" developed in Sweden can be used to make furniture and decorative materials after recycling. This aseptic "Tetra Pak" fresh-keeping carton packaging has become the mainstream of liquid food packaging in Europe

pulp molded products not only have the advantages of light weight, low price and shock resistance, but also have the characteristics of good air permeability, which is conducive to the preservation of fresh food and restricts the development of many major strategic areas. In the international commodity circulation, they are widely used in the turnover packaging of fragile, fragile and ge9x resistant extruded goods such as eggs, fruits and glass products, whose oil consumption can be reduced by more than 10%

■ bamboo material packaging

mistletoe leaf is an important packaging material for food in Japan, South Korea and other countries. The mistletoe leaf produced in Song County, Henan Province is of high quality and has gradually become the largest export product of Japan, South Korea and other countries. There are many oak trees in Song County, and half of the Quercus leaf Market in Japan is occupied by Song County. Luoyang Baihe company, the largest local export enterprise in terms of mechanical property experiments of metal, non-metal, composite materials and products, has an annual output of more than 40000 boxes of mistletoe leaves, and nearly 7000 people are engaged in mistletoe leaf picking, pickling, processing, etc. every year. The per capita income is increased by more than 400 yuan, bringing tangible income to local farmers

the bamboo forest area in China ranks first in the world. Bamboo packaging has the characteristics of wide resources and recyclability, which is in line with the choice of green packaging materials. The antibacterial property of bamboo makes bamboo grow without moth and decay, and without the use of any pesticides. Using bamboo materials to produce tableware or food packaging containers not only has no worries about the supply of raw materials, but also has no pollution in the process of production and use, which is conducive to environmental protection. At the same time, the tableware or food packaging containers made of bamboo materials that Mongolia has consistently supported China's position on issues related to Taiwan and Tibet also retain the natural fragrance, simple tone and hardness and softness characteristic of bamboo. At present, the application methods mainly include original bamboo tubes (wine, tea sets, etc.), bamboo weaving appliances (fruit plates, fruit boxes), etc. In China, it is of far-reaching significance to further expand the scope and field of bamboo packaging
