Green packaging and organic food

green packaging is the packaging with the highest requirements at present, and organic food is the safety and health product with the most stringent requirements at present. The two are consistent from the perspective of health and environmental protection. The safety, environmental protection and harmonious characteristics of organic food determine that its packaging cannot affect human health and the sustainable development of the environment. In many countries' organic product certification standards, the requirements for ecological environmental protection of packaging have been made clear. Therefore, using green packaging has become the first choice for organic food producers. This article will start with green packaging, introduce how to realize green packaging of organic food, and put forward some suggestions on the packaging of exported organic food, hoping to be helpful to organic practitioners

first, green packaging

packaging enables commodities to realize the functions of circulation and exchange, so that commodities can reach consumers safely and conveniently. However, non recyclable packaging also brings a heavy burden to the ecological environment, and the improper selection of packaging materials also threatens human health. In addition, the rise of domestic and international green consumption boom also urgently requires enterprises to use green packaging

1. Concept and development process of green packaging

green packaging is the maximum distance between tightening surfaces: 550mm; (it can be customized according to customer requirements) it is an appropriate packaging that can be recycled, recycled or degraded, and will not cause public hazards to human body and the environment in the whole life cycle of the product. Its basic characteristics are: under the condition of packaging function, it uses the most materials and the least packaging waste; Packaging products are harmless to human health, and waste does not pollute the environment; Waste combustion produces new energy without secondary pollution; Packaging materials can be reused, recycled, or degraded and purified under natural conditions

On June 5, 1972, the United Nations held a conference on the human environment in Stockholm, Sweden, and issued the Declaration on the human environment, which has triggered a worldwide green packaging revolution. In the past 30 years, green packaging has developed rapidly. In 1975, Germany took the lead in responding to the Declaration on the human environment, calling for and launching Green Packaging - "green dot" packaging logo (Der GR ne Punkt). Subsequently, the United Kingdom, Canada, but to general manufacturers, Japan, the United States, the European Community and other countries and regions have also launched green packaging, setting off a worldwide green boom. On January 1st, 1999, the international green environmental protection mark (including packaging mark) was implemented all over the world, accelerating the process of green packaging

in order to adapt to this trend, the voluntary press conference of "China safety and environmental protection certification of food packaging materials" was held in Beijing on April 20, 2005 by the bid winning Certification Center (the former China Energy Saving Product Certification Center). At present, the CNCA has listed plastic bags and plastic lunch boxes for food packaging as the key work of compulsory certification this year. The national "food packaging product certification management measures" is also about to be issued. At that time, all food packaging materials must pass the national certification before they can be put on the market

2. The necessity of developing green packaging

(1) environmental protection requirements

taking China as an example, China now publishes the "directory for the implementation and utilization of the first (set) major technical equipment" every year. The output of packaged products is about more than 30 million tons, while the recovery rate of other products is quite low, and the recovery rate of the whole packaged products is less than 20% of the total output, except for cartons, beer bottles and plastic turnover boxes. According to this calculation, more than 25 million tons of packaging waste are produced every year. As there is less and less land for landfilling garbage, so much packaging waste cannot be digested, which makes the accumulation of garbage in many cities very serious. However, those packaging wastes that cannot be degraded by the environment cannot be treated in a timely and harmless manner, and people's awareness of environmental protection is not strong, resulting in serious waste loss. Environmental pollution caused by packaging waste has seriously affected the sustainable development of social economy. Therefore, it has become a social focus of public concern to comprehensively promote green packaging and reduce the pollution of packaging waste

(2) requirements for sustainable development

take plastics as an example. The traditional plastic production with oil as raw material is subject to the supply of oil. The rapid development of China's economy has accelerated the consumption of oil. China's oil production has been unable to meet its own needs. At present, China has become the world's second largest oil importer, and the world's oil storage is expected to be exhausted in about 60 years. At the same time, the volatile situation in the Middle East has seriously affected the supply of oil. Therefore, seeking alternative substances has become the top priority in the development of the packaging industry

(3) requirements for dealing with green barriers and developing foreign trade `

green trade barriers have various forms, mainly including: Green tariff system, green technology standard system, green environmental labeling system, green packaging system, green subsidy system, green health and quarantine system, etc. Among them, the green packaging system refers to: developed countries 8 Pollution free and other countries have formulated high and relatively perfect standards for packaging materials, including waste recycling, reuse and regeneration systems, which are environmental protection measures taken to prevent packaging materials and the packaging waste they form from causing harm to the environment, or packaging containers with unreasonable structures may damage the health of users. However, some overly strict green packaging systems may hinder the foreign trade of developing countries and cause trade disputes. More and more people realize that promoting green packaging and keeping up with the trend of international green packaging is the only way to meet the needs of the development of domestic and foreign trade. According to the statistics of the United Nations statistics office, 90% of Americans, 89% of Germans and 84% of Dutch people will consider the environmental protection standards of products when buying goods. Governments of various countries have also taken corresponding measures to adapt to the upsurge of green consumption: in order to promote renewable utilization and the use of recycled packaging products, the EU stipulates that packaging products that cannot be reused or recycled will be excluded from the market from 2000; The United States, Canada, Japan, Singapore, South Korea, the Philippines, Brazil and other countries have also formulated packaging laws and regulations. According to the World Packaging Organization Council, the United States, Japan, Singapore, South Korea and European countries have completely banned the use of PVC packaging materials. In addition, Denmark also prohibits the use of disposable beer and beverage containers and the import of beer and beverages packaged in such containers. The h.b51917 bill of Connecticut in the United States stipulates that the use of non recyclable substances in the packaging of consumer goods has been prohibited since 1995. Green packaging has become a shield for western developed countries to prevent developing countries from entering the international market. Therefore, developing green packaging and promoting the export of our products have become an important part of China's economic development

II. Organic food and green packaging

l. Organic products should be packaged in green packaging

plastic bags are more commonly used in organic food (such as grain, vegetables, etc.). According to experts, in order to improve the performance of some plastics, plasticizers and anti-aging agents are added, which are often toxic. PVC is also a kind of commonly used plastic. Additives are used in its production. Eating food packaged with this material may cause chronic lead poisoning. In addition, whitened paper is widely used in food packaging (such as carton milk), and most of the paper is treated with fluorescent brighteners in order to improve its whiteness in the production process. Fluorescent brightener is a chemical substance with strong carcinogenic activity. Although it can bleach, it has a great toxic effect on humans and animals. There are also many high-end food packaging using tin foil. It is understood that the lead content in 60% of tin foil exceeds the hygienic allowable index, and lead is recognized as the "culprit" of acute and chronic heavy metal poisoning. It can be seen that the safety of organic food packaging can not be ignored

organic food refers to edible agricultural products, wild products and other processed products from organic agricultural production system or wild ecosystem, which are produced and processed according to organic certification standards, and have been certified by qualified certification agencies. It is currently the most stringent requirements of safe and healthy food, reflecting the organic concept of safety, environmental protection and harmony. The corresponding packaging should also reflect this principle, so as to achieve safety, environmental protection, simplicity and harmony, which are exactly the concepts of green packaging. So how to achieve green packaging? Generally, the green packaging design scheme is put forward on the basis of fully mastering the market and material information, mainly including: Determination of intention, determination of design parameters, such as the volume and measurement value of packaged goods, preparation capacity or allowable deviation parameters (including pre packaging, transportation packaging and sales packaging); The design performance, including the shape and style of form and structure, graphics, text, color, etc., should meet the aesthetic needs of green products. Here we mainly introduce the following two points:

(1) packaging design

on the basis of meeting the basic needs of consumers, consumption patterns and the environment, the following methods or suggestions should be adopted as far as possible in packaging design

a. considering the recyclability of packaged products, through the design of structure and materials, the packaging after use is convenient for disassembly and classification. For example, designing a creased package can not only reduce the occupied space, but also easily flatten the container after tearing the bottom, which is convenient for recycling. The production cost of this kind of packaging is also very low

b, choose less packaging materials. Chaplin, a British university professor, developed a formula that can save wrapping paper - (2l+2h{+x) × (b+2h), in the equation, l is the length of the gift, h is the height, B is the width, and X is the overlapping length of the wrapping paper. The calculation result of the formula is the area of the wrapping paper, that is, the length of the gift and the height of the gift are multiplied by 2 respectively, then added, and the overlap to be reserved is added. The sum of the three is multiplied by the sum of the width of the gift and twice the height of the gift. In this way, the answer is the minimum wrapping paper area required for wrapping the gift. Other similar packages can be calculated by this method

c. reduce the pollution to the environment and food through the design of manufacturing process. The current research results show that the environmental load in each measurement unit is proportional to the process treatment time, and the successful design strategy is how to shorten the process treatment time. In addition, the pollution of ink on food should not be ignored

(2) material selection

the characteristics of materials often determine to give full play to the efficiency of materials in the production process and use process. On the basis of ensuring the product intention and image design, green packaging materials should be non-toxic, less pollution, low energy consumption, low cost, easy to treat and recyclable materials. At the same time, the selected materials should also be non staining or less pollution in processing. Specific requirements are as follows:

a. environmental safety. Consider whether the soluble substances of the selected materials dissolved in water, oil and other solvents are harmful; Whether the selected auxiliary materials contain toxic and harmful metals such as lead, mercury and cadmium; Whether there are harmful substances discharged in the process of material recycling

b, save resources and energy. Try to use low-density packaging materials; Try to choose materials with low total energy consumption in the material life cycle; Try to use recyclable materials; Reduce the type and quantity of materials as much as possible. Wu8

C. functionality of packaging materials. The selected materials should have effective protection products
