It is a complicated task to select the appropriate materials to meet the requirements of sustainable production when designing packaging products. It is also a process that comprehensively considers the material properties, environmental factors and knowledge in the field. Therefore, the designer is deeply involved. , Detailed and detailed understanding and mastering of packaging materials with environmental protection functions and applied to green packaging design practices to minimize the pollution of materials, maintain the ecological balance of the natural environment and social environment, and also promote the use of earth resources by the packaging industry. Consumed type to recycling regeneration type conversion.

In the early stages of industrialization, the impact of materials on the environment was seldom considered, but the choice of materials in the green packaging design is crucial. It not only determines the degree of product damage to the environment, but also determines the recyclability of the product. It is a complicated task to select appropriate materials for the design of packaging products so that they can meet the requirements of sustainable production as much as possible. It is also a process that comprehensively considers the properties of materials, environmental factors and knowledge in the field. Therefore, designers are deeply Detailed and detailed understanding and mastering of packaging materials with environmental protection and applied in green packaging design practices to minimize the pollution of materials, maintain the ecological balance of the natural environment and social environment, and also promote the use of earth resources by the packaging industry. Type to recycling regeneration.

First, green packaging design material characteristics

1. Material characteristics and applications

The characteristics of the material often determine the effectiveness of the material energy in the production process and use. Green packaging materials should use low-energy, low-cost, less-polluting materials, and the selected materials are easy to process, with no pollution or less pollution during processing. For example, self-destructive plastics in self-destructive materials designed and researched by China's scientific research institutes for environmental protection include the addition of special ultraviolet photosensitizers to polyolefins. These plastics can be rapidly decomposed after they are used. Therefore, the selection and application of green packaging materials mainly consider the following factors.

1) Use the same packaging material when designing similar packaging products to facilitate recycling. For example, WHIRLPOOL Germany reduced the amount of materials used for packaging from 20 to 4 to reduce the cost of waste disposal to 50%.

2) Full consideration should be given to the recycling of materials, which not only saves raw materials but also facilitates the recycling of resources.

3) Design should consider the degradability of materials. In 1997, the State Environmental Protection Agency announced the environmental labeling and product technical requirements for biodegradable plastic packaging products, and the implementation of the sign recognition system for biodegradable plastic packaging products will greatly improve the pollution status of plastic packaging.

4) Design and produce packaged products that can be re-used for re-use. For example, an ultra-strength bottle developed by a Japanese beer company such as Asahi and Zhaji has doubled its life expectancy compared to the original bottle, and can be used by customers for up to 16 years. Environmental significance is greatly superior to disposable packaging. .

2. Re-understanding of traditional natural packaging materials

Our ancestors began to make direct use of the existing materials around them and packaged their labor and life. The unique quality of the green packaging and the packaging style of the nation were formed. Pure natural value and environmental protection are still not lost its glory.

Plant leaf packaging. These materials include bamboo leaves, lotus leaves, loquat leaves, and the like. For example, in Guangdong's gourd tea, it directly uses the natural bamboo leaves, and a section of the brown tea is tied with fine straw ropes to form small balls that are connected together, resembling the pressurizing gourd that grows in the north. The method of packaging the tea leaves in the original bamboo leaves in the flavor unchanged for a long time, when drinking, at any time can be untied above the straw rope, remove the tea in which the rest of the gourd is still kept under strict storage.

Grass fiber packaging. This is a unique form of packaging in Yunnan, China. People living here have long-term cultivation of rice and poultry. Since eggs are exchanged for items, weaving straws with elastic and strong straw into reticular pouches that can hold eggs, the eggs that are wrapped in straw nets are pink and fresh, giving people a natural and natural freshness. Yunnan eggs are worn with ropes.

Bamboo packing. Our ancestors became indissolubly linked to bamboo and bamboo in the working life of generations. Bamboo rafts have been used as packaging devices for people today.篓 is made of tough and strong bamboo strips, with no trivial detail on the top. It has the pristine beauty typical of natural materials. Various kinds of foods are placed in them. The gap between thin bamboo strips is transparent and natural, and the food is not easily degraded.

Green package design as a new design idea and method. It has attracted wide recognition and attention from all countries in the world. At the same time, it has stimulated the attention of the natural environment at various stages of the cycle of green packaging products, and has formed a green packaging product project with green packaging product design as a leader. Therefore, it is imperative to put green packaging design as a strategy. It will promote the better and faster development of our country's art design and packaging industry toward humanistic survival. Introducing green packaging design into the field of packaging engineering also provides designers with a new thinking point and opens up a new path. As a packaging designer, it is more necessary to devote more energy to the technical system and aesthetic thinking in this field. We are convinced that advocating green packaging design and creating an ecological, humane packaging space with sustainable development will surely become the mainstream of packaging design.

Second, green packaging design principles, methods

The green packaging design must follow the principles of 3R1D, that is, reduce the consumption of packaging materials, refill use of packaging containers, recycling and recycling of packaging materials, and the degradability of packaging materials, but how to implement its basic ideas into the conventional product design and development process In order to form an overall pattern of a practical and feasible green packaging design process, it is the key to the universal acceptance and application of green packaging design. There are mainly the following methods to regulate the green packaging product design process:

1. Function, considering the function of green packaging design, mainly to make the use of the product more reasonable, the basic idea is to analyze the function of the product in detail to determine what is the most basic functional characteristics, and further evaluate the realization of these functions. Whether it consumes less materials and energy, it imposes the least load on the environment. The design process is:

1) Quantitative definition of the functional value of the product, identifying the basic parameters that correspond to the functional value;

2) List the objectives and theoretical and practical measurement parameters for the specific functions of the packaged product;

3) Assess the consumption of materials and energy in each functional unit, analyze based on theoretical and practical measurement parameters, in order to study whether these functions can be achieved with less material and energy consumption;

4) Compare new packaging products and reference products and optimize new product design and development countermeasures.

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

1) Identify the form, mass, category, property, and scope of transportation of the packaged goods, analyze and determine the structural functions of the packaged products, or the functions of the accessories, and further clarify the purpose of the packaged products.

2) Analyze the overall structure and function of the packaging design, and scrutinize whether the relevant functions can be combined or the number of attachments reduced, and whether the materials are used most reasonably.

3) Whether it can also save material and reduce the volume and weight. In the material structure:

(1) The properties of packaging materials are reasonably configured with the use of packaging;

(2) The overall analysis of the product's material composition and detachability, the use of effective;

(3) Reduce the number of material types in the same packaged product as far as possible so that they can be classified and recycled.
