What is green packaging material? Basic principles of green packaging design

by admin

green packaging generally has five connotations:
1) implement packaging reduction (rece). Under the condition of meeting the functions of protection, convenience and sales, the amount of packaging should be the least
2) packaging should be easy to reuse or recycle. Improve the production and reuse of composted products through measures such as soil recycling and incineration
3) packaging waste can be degraded and decomposed (). It will not form permanent waste in the end, so as to improve the soil. Rece, reuse, recycle and are the universally recognized 3r1d principles for developing green packaging
4) packaging materials shall be non-toxic and harmless to human body and organisms. Packaging materials shall not contain toxic elements, bacteria and heavy metals; Or these contents should be controlled below the relevant standards
5) the whole life process of packaging products from raw material collection, material processing, product manufacturing, product use, waste recycling to final treatment should not cause public hazards to human body and environment
grading of green packaging
green packaging is divided into Grade A and Grade AA
1) class a green packaging refers to the appropriate packaging that can recycle, recycle or degrade the waste and contains toxic substances within the specified limit
2) AA grade green packaging refers to the appropriate packaging in which waste can be recycled, recycled or degraded, which does not cause public hazards to human body and environment in the whole life cycle of the product, and contains toxic substances within the specified limit
the above classification is mainly to solve the problem of waste after packaging, which is the pollution in the process of environmental protection all over the world. It is a problem that needs to be solved in the past, now and in the future. Life cycle analysis (LCA) is not only a method to comprehensively evaluate the environmental performance of packaging, but also a method to compare the environmental performance of packaging materials, but there should be priority in solving problems
the role of green packaging
green packaging is conducive to protecting the natural environment and avoiding environmental damage caused by waste. Some of the chemical components contained in the packaging materials may have some influence on the surrounding environment. For example, the components such as ethylene that are used for evaporation in the foam restaurant are seriously exceed the standard. In the long term, the environment will cause serious damage to the surrounding ecological environment and form a white pollution zone. Green packaging and strict control of packaging materials can avoid the adverse impact of waste on the environment. In addition, the use of green packaging can reuse packaging materials, which is conducive to increasing relative resources and alleviating the current situation of resource shortage. Therefore, green packaging has both economic and social benefits, which is the organic unity of the two. It is a dynamic concept. With the progress of science and technology, the general trend of green packaging is to gradually minimize the total cost of service cycle on the basis of environmental protection
ways of green packaging
the ways of green packaging mainly include: promoting the production department to adopt packaging that is as simple as possible and made of degradable materials; In the process of circulation, measures should be taken to realize the rationalization and modernization of packaging
(1) modularization of packaging. The standard for determining the basic size of packaging, that is, packaging modularization. After the packaging module standard is determined, all kinds of products entering the circulation field need to be packaged according to the size specified by the module. Modular packaging is conducive to the collection of small packages, and containers and pallets are used for packing and loading. If the packaging module can be unified with the size module of warehouse facilities and transportation facilities, it is also conducive to transportation and storage, so as to realize the rationalization of logistics system
(2) large scale and container packaging. It is conducive to the mechanization of the logistics system in the process of loading and unloading, relocation, storage and transportation, accelerate the operation speed of these links, reduce unit packaging, save packaging materials and packaging costs, and protect the goods. Such as container, container bag, pallet and other container loading methods
(3) multiple and repeated use of packaging and disposal of waste packaging. General packaging is adopted without special arrangement for return; Turnover packaging is adopted, which can be used repeatedly, such as beverage, beer bottle, etc; Cascade utilization: the packaging after one-time use can be used for other purposes after use or simply treated for other purposes; The waste packaging materials are recycled and transformed into other uses or new materials
(4) develop new packaging materials and packaging appliances. The development trend is that the packaging materials are highly functional and use less materials to realize a variety of packaging functions.
