Green Packaging: The Inevitable Choice for Chinese Enterprises (Part Two)

Second, the connotation and characteristics of green packaging

Green means natural growing plants. Metaphor means that the plants are flourishing, vibrant, representing life and vitality; green packaging, that is, can be recycled, reused or degraded, and does not cause harm to the human body and the environment throughout the product life cycle. Moderate packaging of public hazards is called green packaging. Green packaging generally has four connotations, namely: the most provincial materials, the least waste, and save resources and energy; easy recycling and recycling; waste combustion produces new energy without secondary pollution; packaging materials and Decompose on your own without polluting the environment. Therefore, the goal of promoting green packaging is to conserve maximum natural resources, minimize the amount of waste and minimize environmental pollution. The connotation of green packaging is also doomed to different characteristics from other packaging:

1. Ergonomics

The new century's green packaging will be developed in accordance with the trend of ergonomics, that is, ergonomic packaging, that is, easy to use, reasonable handling, reliable storage, easy interpretation, and meet the special psychological and physiological needs of various groups of consumers, especially the elderly. Group consumers. European and American countries have Ergonomics packages specifically designed for older people or patients.

2. Low emission of harmful substances

The low discharge of green packaging includes two aspects. First, waste water, waste gas and waste discharged from packaging materials containers during production and processing are low. The second is that the additive in the packaging container material should be low or zero during the service life. For example, lead, tin in cans, lead and cadmium in ceramics, lead, chromium in printed matter, lead, mercury, and ethylene in plastics, formaldehyde in coating, etc. should meet safety and health standards to ensure consumption. Health.

3. Protect the environment

In the new century, green packaging should consider the balance of the entire eco-environment and choose environmentally friendly packaging containers (materials) and packaging designs. For example, new macromolecule synthesis technology should be used to connect the polymer chain with decomposable The structural unit makes this material photodegradable or biodegradable and bio-photo-degradable. Recently, the State Economic and Trade Commission issued an emergency notice to stop production of disposable foam tableware, make replacement products, stop "white pollution" and protect the environment.

The other is that the edible packaging material replaces the traditional plastic packaging technology. This technology effectively solves the contradiction between packaging materials and environmental protection. At present, there is an edible packaging film with soybean protein and starch mixed on the market, which can keep moisture and block oxygen. Maintain the original taste and nutritional value of food. The other is chitosan edible packaging film, which is extracted from shellfish chitosan, combined with lauric acid to produce a homogeneous edible film, has a good freshness, there is also the use of chitosan As raw materials, processed into packaging paper, can be used for instant noodles, condiments, bread, food and other packaging.

Another bean curd residue is the waste in the tofu production process. China's annual production capacity is 800,000 tons, making full use of this waste resource. It is very ideal to use it as a raw material to make packaging containers, which saves raw materials and avoids the environment. Pollution, but also added value, the process is to the right proportion of bean curd residue, pulp and calcium hydroxide mixed, add water, heated at 5-80 ° C for two hours, and then filtered, the filtered material can be molded Various containers are finally dried. Such containers are high in strength, light weight and impervious to water. The product can be decomposed after it has been buried underground for three months.

4. Save energy resources

China is a resource-rich country and a resource-poor country, which means that the total amount of resources is large and the per capita amount is small. Therefore, the principle of energy conservation must be followed when developing green packaging. First, raw materials and process technologies that use energy conservation are selected for processing and packaging materials. Second, they are turned into new resources and energy for humanity.

China is a country with a large population and relative lack of resources. Developing "green packaging" is an inevitable choice for China's packaging industry and a trend for the development of packaging design in the new century. Faced with this development trend, we should do the following: First, we must pay attention to the development and replacement of packaging materials. The international packaging industry has entered the era of developing environmentally-friendly materials and replacing traditional materials. China's packaging industry should also actively follow up. The second is to pay attention to the recycling and reuse of packaging waste, save energy and resources. The third is to actively adapt to the global green consumer fashion, promote and guide the development of commodity packaging toward the “green packaging”, so that “green packaging” is supported by consumers and the whole society. Fourth, the government should take corresponding measures to encourage the use of renewable and recycled packaging products. The fifth is to improve the green packaging regulations and management system as well as the rules and regulations for the recycling and disposal of packaging wastes as soon as possible so that green packaging will become legal.

Commodity packaging design can guide the change of production methods and consumer lifestyles. It plays an important role in the economic and cultural development of the society. In the packaging design, we should consider the design orientation from the perspective of the overall social development, and advocate green. Packaging promotes the coordinated development of economy and ecology and makes society more civilized.
