Natural materials have great potential in the field of green packaging

green packaging is also called environment-friendly packaging. Generally, the mouse graphics may be displayed in the shape of "busy task", which 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, Sweden must timely repair the "Tetra Pak" aseptic fresh-keeping carton packaging developed at this time. The stored food can be kept fresh for 6 months without refrigeration. After recycling, the packaging can be used to make furniture and decorative materials, This aseptic "Tetra Pak brick" 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. In the international commodity circulation, many new materials are widely used, which do not have the corresponding construction convenience. They are used in the turnover packaging of fragile, fragile and extrusion resistant items such as eggs, fruits and glass products

bamboo material packaging

mistletoe leaf is an important food packaging product in Japan, South Korea and other countries. The mistletoe leaf produced in Song county is of high quality and has gradually become the largest supplier in Japan, South Korea and other countries. There are many oak trees in Song County, so the local farmers are guided to engage in the processing and sales of Quercus leaves for export green food packaging. Half of the mistletoe market in Japan is occupied by Songxian. Luoyang Baihe company, the largest local export enterprise, has an annual output of more than 40000 boxes of mistletoe leaves. Every year, nearly 7000 people are engaged in mistletoe leaf picking, pickling, processing, etc., with an increase of more than 400 yuan per capita, bringing considerable 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 selection principle 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, tableware or food packaging containers made of bamboo materials also retain the unique natural fragrance, simple tone and hardness and softness characteristics of bamboo. At present, the application methods mainly include original bamboo tubes (wine, tea, 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

edible packaging

edible packaging refers to transforming it into an edible raw material when it is about to become "waste" after the packaging function is realized. Edible packaging is a kind of paper like packaging material processed from edible raw materials. This special packaging that can realize the transformation of packaging function is edible packaging. Edible packaging can be divided into two categories: one is to make edible paper-based food packaging as thin as paper by adding common food raw materials such as starch and sugar paste, and then adding some flavoring substances; The other is the modification of edible non-toxic fiber, and then add some food additives to make an edible "paper", which can be used as food packaging. Nowadays, food packaged in "food paper" with beef flavor, chicken flavor, apple flavor and other flavors has appeared in the market, which is very popular with consumers, especially the application of edible paper food packaging in cold drink packaging, which plays a role in keeping cold and sanitation

the cereal film developed by Clemson University in the United States uses corn, soybean and wheat as raw materials, and the extracted plant protein is processed into a film, which can not only maintain moisture, but also has good moisture and oxygen resistance, and has certain antibacterial properties. It is suitable for the packaging of sausage and other foods, and can be used for poultry consumption or as fertilizer after use. Corn protein packaging film is suitable for the packaging of high fat foods with heavy oil and strong permeability, as well as the inner layer of fast food boxes and other oily foods. A company in Queensland, Australia, developed an edible potato chip packaging, which can be eaten by people after eating potatoes without causing waste; Japan has developed edible wrapping paper made of deacetylated chitosan extracted from shell substances. The fast-food noodle seasoning packaged in this edible wrapping paper can be directly cooked in hot pot. The use of edible packaging not only facilitates consumers' living consumption, but also avoids packaging waste pollution, which is worthy of further research and promotion. Using chitosan edible packaging film as food packaging material solves the contradiction between food packaging waste and environmental protection. The research results include more than 50 tables, 16 charts and diagrams, and the preservation of candy, preserved fruits, cakes, moon cakes, etc

edible "vegetable paper" packaging is very popular with consumers. The "vegetable paper" made by washing, peeling, cutting, cooking, cooling, drying and then processing vegetables has a bright appearance, which is very easy to induce customers' desire to buy. People can eat the food packed with this kind of "paper" without tearing the "wrapping paper". Experts estimate that a piece of "vegetable paper" is equivalent to the nutritional value of 250 grams of fresh vegetables. Because the edible paper food packaging has the function that can not be replaced by any other food packaging, it has many varieties and properties, and is very widely applicable to the internal and external packaging of all kinds of raw and cooked food, and it is very convenient to use. China is rich in resources and has a large population, and its food consumption ranks first in the world. Vigorously developing edible paper food packaging has been favored by many scientific research institutions, manufacturers and businesses, and has become a food packaging with great development prospects
