What is green packaging, among which 4r1d is the principle

by admin

green package, also known as pollution-free package and friendly package, refers to a package that is harmless to the ecological environment and human health, can be reused and regenerated, and is in line with sustainable development. Its concept has two meanings: one is to protect the environment, the other is to save resources. The two complement each other and are inseparable. Among them, protecting the environment is the core, and saving resources is closely related to protecting the environment, because saving resources can reduce waste, which is actually the protection of the environment from the source

the green packaging design principle of “4r1d” in developed countries
looking at today’s paper packaging and printing technology, we find that its development has the following new characteristics:
1 Single layer materials are developing towards multi-layer materials
2 Offset printing, gravure printing, flexographic printing, screen printing and other printing methods coexist, among which flexographic printing will grow the fastest
3 The development of single sheet paper to web paper and single machine to on-line production, so as to realize the supply of complete sets of equipment
4 The comprehensive application of various relevant new technologies (such as computer design, digital technology, laser processing technology and new materials) continuously optimizes the whole production system
5 It is increasingly restricted by increasingly stringent environmental protection and health standards
in addition, we must solve the ten key technical problems in the development of paper packaging industry:

it is understood that the use of plastic food bags is gradually prohibited in domestic and foreign markets, and the use of non-toxic and harmless “all paper environmental protection paper bags” packaging is advocated. There are four reasons:
1. Paper products can be burned as energy
2. Paper packaging can use water-soluble glue and ink without oily solvent or low oily solvent, which is cheaper and conducive to environmental protection
3. Paper products are highly sustainable and can be reused
4. Paper packaging waste will not pollute the environment and can also be used as fertilizer
the above four points are in line with the green packaging design principle of “4r1d” in western developed countries. Under the international trend, the development market of paper packaging is very broad. Moreover, under the background of green and environmental protection, packaging paper is mostly made of fiber raw materials, which is physically and chemically treated according to the packaging requirements. Compared with fragile glass, too expensive and heavy metal and poor degradability of plastic, packaging paper has become the best choice of green packaging materials.
