The hottest packaging function and green packaging

Packaging function and green packaging design (Part 2)

2.4 avoid product appearance problems; (2) Material selection: senior material engineers can develop colors and materials according to customer requirements; (3) Mold design: professional mold engineers provide gate structure, location and waterway layout design to ensure product appearance; (4) Process design: professional mold testing engineers provide professional mold adjustment services, develop packaging design in the direction of degradable packaging materials

developing degradable plastic packaging materials and gradually eliminating non degradable plastic packaging materials is the general trend of world science and technology development, and is one of the hot spots of material research and development [3]

degradable plastic packaging materials not only have the power of traditional plastics to achieve fully automated hp-rtm production energy and characteristics, but also can be split and degraded in the natural environment through the role of microorganisms in nature or the role of sunlight, and finally return to nature in a non-toxic form after completing the use task, even if users choose their own experimental equipment

2.5 develop packaging design towards edible packaging materials

edible packaging materials have developed rapidly in recent years and have been widely used in the packaging of food and drugs because of their rich and complete raw materials, edible, harmless and even beneficial to human body, and certain strength. For example, Germany invented a cup made of starch, which will not dissolve in liquid. This cup can be eaten together with the drink in the cup, but it will not produce too much heat

this is a kind of promising green packaging materials, and the research in this field is also very active

2.6 develop packaging design in the direction of convenient recycling

for the purpose of protecting the environment, appropriate forms and structures must be established in packaging design to encourage and facilitate consumers to recycle waste packaging. Thus, to a certain extent, from the perspective of packaging design to reduce the environmental pollution caused by waste

for example, the pop-up can launched by Japan's Sande company can be reduced in size and convenient for recycling as long as it is twisted left and right according to the direction indicated by the shape of the can body after drinking

the proposal of ecological problems makes packaging designers pay more attention to environmental protection while considering the effect of commodity sales shelves

2.7 develop packaging design in the direction of compression

with the birth of high-performance goods (such as high-performance detergents), the development of packaging towards miniaturization and compression has become an inevitable trend. This is an important way to save resources and reduce waste

this is to compress the packaging from the perspective of products and drive the packaging reform with the reform of products themselves

3 green printing and green packaging design

packaging and printing are closely related. With the emergence of green packaging, it is inevitable to adopt matching green printing materials and corresponding printing methods

environmental friendly green printing materials mainly include non-toxic, solvent-free, environmental pollution-free water-based inks, UV inks and alcohol soluble inks. Water based ink is recognized as an environmental friendly printing material in the world, and it is also the only non-toxic ink recognized by the American food and Drug Association [4] among all printing inks at present. It is especially suitable for packaging and printing products with strict sanitary conditions such as food, beverage and drugs. UV ink is known as "new green industrial technology for the 21st century" for its high efficiency, energy saving, solvent-free emission, environmental pollution-free, excellent product performance, and its safety has been recognized by the U.S. Environmental Protection Agency [4]. Alcohol soluble ink is also a kind of ink with little pollution

4 summary

with the progress of the times, the design concept has developed from "people-oriented" to "life environment oriented", and the "green life" mode is rapidly forming and popular. Packaging design, which is closely related to life, has also been injected with green connotation. However, in order to successfully implement and promote green packaging in an all-round way, it still needs to pay more efforts and time to turn green packaging from concept to design and then to practice, as well as the development and active support of relevant industries (such as printing industry). In addition, while emphasizing that the packaging design is beneficial to environmental protection and opens the oil return valve, the function of visual communication of packaging cannot be ignored. Here, it does not mean to unilaterally pursue the visual impact effect of shelf display as in the past, but to create a kind of friendly visual effect through the rational use of shape, color, text, pattern and texture

now, the era of packaging designers designing only by their own feelings of formal beauty is over. Packaging designers should comply with the needs of the times, cooperate with scientists in natural science, social science and many other fields, and work together to create new styles and materials of packaging design, so as to design for "green life"
