China's green packaging design materials and principles

how to select appropriate materials to meet the requirements of sustainable production to the greatest extent is a complex task when the fatigue testing machine is mainly used for the fatigue life test of various spiral springs, Belleville springs, shock absorbers, seal springs and other packaging products. It is also a process that comprehensively considers material performance, environmental factors and knowledge in this field. Therefore, The designer deeply, carefully and concretely understands and grasps the packaging materials with environmental protection function and applies them to the practice of green packaging design, so as to minimize material pollution, maintain the ecological balance of natural environment and social environment, and promote the transformation of the use of global resources by the packaging industry from consumption to recycling

in the early stage of industrialization, little consideration was given to the impact of materials on the environment, but the selection of materials in green packaging design is crucial. It not only determines the degree of environmental harm of products, but also determines the recyclability of products. How to select appropriate materials to meet the requirements of sustainable production to the greatest extent in packaging product design is a complex task and a comprehensive consideration of material performance, Environmental factors and the process of knowledge in this field. Therefore, in the process of deeply, carefully and concretely understanding and mastering the packaging materials with environmental protection functions and applying them to the practice of green packaging design, designers minimize the pollution of materials, maintain the ecological balance of natural environment and social environment, and promote the transformation of the use of global resources by the packaging industry from consumption to recycling

I. characteristics of green packaging design materials

1 Characteristics and application of materials

the characteristics of materials often determine the efficiency of giving full play to the energy of materials in the production process and use process. The green packaging materials shall be low energy consumption, low cost and less pollution materials. At the same time, the selected materials are easy to process and have no or less pollution during processing. For example, the self destructible plastic in the self destructible materials designed and developed by Chinese scientific research institutions for environmental protection is a special UV photosensitizer added to polyolefins, which can be quickly decomposed after using waste. Therefore, the selection and application of green packaging materials mainly consider the following factors

1) try to use the same packaging materials when designing similar packaging products to facilitate recycling. For example, whirlpool Germany has reduced the number of packaging materials from 20 to 4, reducing the cost of waste treatment to 50%

2) fully consider the recycling of materials, which not only saves raw materials, but also facilitates the recycling of resources

3) the degradability of materials should be considered in the design. In 1997, the national environmental protection bureau published the environmental label and product technical requirements for degradable plastic packaging products, and implemented the label recognition system for degradable plastic packaging products, which will greatly improve the pollution status of plastic packaging

4) design and produce reusable packaging supplies. For example, a kind of super strength wine bottle developed by Japanese beer companies such as Asahi and Sapporo has doubled its service life compared with the original bottle and can be used by customers for up to 16 years. Its environmental protection significance is greatly superior to one-time packaging

2. Recognition of traditional natural packaging materials

our ancestors began to directly use the existing materials around them long ago to deal with the problems of their simply supported beam impact testing machine as follows: the things used in labor and life were packaged, forming a distinctive green packaging quality connotation and national packaging style, which contains simple natural value and environmental protection meaning and still has its dazzling luster

plant leaf packaging. These materials include bamboo leaves, lotus leaves, and reed leaves. For example, Hulu tea in Guangdong directly applies natural bamboo leaves to tie up brown tea powder section by section with thin straw ropes to form connected small balls, which is quite similar to the waist pressing Hulu grown in the north. The tea packaged in this way has a long-lasting fragrance in the original bamboo leaves. When drinking, you can always untie the straw ropes above, take out the tea powder, and the rest will continue to be tightly stored in the lower Hulu

straw fiber packaging. This is a unique packaging form in Yunnan, China. People living here grow rice and raise poultry for a long time. Since eggs are used to exchange goods, elastic and strong straw is used to weave into straw bags that can hold eggs. The eggs wrapped in straw are pink and fresh, giving people a natural and fresh feeling of the original flavor. It is said that eggs are worn with ropes in Yunnan

bamboo packaging. Our ancestors formed an indissoluble bond with bamboo and wood in their working life for generations, and bamboo baskets have been used as packaging utensils by people until now. The basket is simply woven with strong tenacity and strong bamboo strips. There are no superfluous details on the basket, which gives the unique simple beauty of natural materials. All kinds of food are placed in the basket. The gap between the thin bamboo strips is transparent and natural, and the food is not easy to deteriorate

green packaging design is a new design idea and method. It has been widely recognized and valued by countries all over the world. At the same time, it drives the attention to the natural environment at all stages of the cycle of green packaging products, and forms a green packaging product project led by the design of green packaging products. Therefore, it is very necessary and urgent to put forward green packaging design as a strategy, which will promote China's art design and packaging industry to develop better and faster in the direction of humanized survival under the guidance of the government's industrial policies. The introduction of green packaging design into the field of packaging engineering also provides a new thinking point for designers and opens up a new path. As a packaging designer, we need to put more energy into the technical system and aesthetic thought in this field. We firmly believe that advocating green packaging design and creating ecological and humanized packaging space with sustainable development will become the mainstream of packaging design

II. Principles and methods of green packaging design

green packaging design must follow the principle of 3r1d, that is, reduce the consumption of packaging materials, refill the packaging containers, recycle the packaging materials and make the packaging materials degradable, but how to implement its basic ideas into the conventional product design and development process, so as to form a practical overall pattern of the green packaging design process, Is the key to the universal acceptance and application of green packaging design. There are mainly the following methods to standardize the design process of green packaging products:

1. Function. Considering the green packaging design from the function is mainly to make the use purpose of the product more reasonable. Its basic idea is to analyze the function of the product in detail to determine what is the most basic functional characteristics, Further evaluate whether the realization of these functions consumes less materials and energy and causes the minimum load to the environment. The design process is:

1) quantitatively define the functional value of the product and identify the basic parameters corresponding to the functional value

2) list the objectives and theoretical and practical measurement parameters for the specific functions of packaging products

3) evaluate the material and energy consumption of each functional unit, and analyze based on theoretical and practical measurement parameters, so as to study whether these functions can be realized with less material and energy consumption

4) compare new packaging products with reference products, and optimize new product design and development countermeasures

2. Structure. Analyzing the green packaging design from the morphological structure of loosely packed products is mainly to make the packaging structure more scientific, practical and beautiful. At this level, first of all, carefully determine the basic concept of product attributes, and consider how to improve the impact of products on the environment under its framework. In the design process, it is necessary to analyze not only the functional structure of products, but also the material structure of products. In terms of functional structure:

1) clarify the form, volume, category, attribute and transportation range of the packaged goods, analyze and determine the structural function of the main body of the packaged products or the function of the accessories, and further clarify the use purpose of the packaged products

2) analyze the overall structure and function of the packaging design, and consider whether relevant functions can be combined or the number of accessories can be reduced, and whether the materials are used most reasonably

3) whether it can save materials and reduce volume and weight. In terms of material structure:

(1) the properties of packaging materials are reasonably configured with the packaging purpose

(2) analyze the material composition, disassembly and use effectiveness of the product as a whole

(3) try to reduce the number of material types in the same packaging product for classification and recycling
