Green Packaging Design (in)

2. To research and develop packaging materials and production processes that are beneficial to human health and environmental protection. At the design stage, sufficient market research and technical analysis are performed on the requirements for packaged products, such as the range and degree of human health damage in the process of production, use, and waste recycling, and the design and control measures to eliminate and control pollution sources. Packaging materials are designed logistics media, especially packaging materials used in the packaging of daily necessities, such as food and clothing. Part of the contact with the person and the dust in the use mode, the chemical residue of the attachments, and the diffusion of gas have an impact on people's health. It is difficult to measure and prevent dangerous situations, but the designer's environmental awareness has prompted him to select materials that are non-toxic, non-polluting, recyclable, and degradable at the design stage. Rationally design the packaging structure, achieve maximum reduction of packaging products from functions, consumables, and printing processes, avoid superposition of packaging structure, level, and volume, and exhibit excessive packaging and exaggeration packaging phenomenon, and use unrealistic devices Mislead consumers.
3, green packaging design to determine the target from the various stages of the packaging product cycle. Green packaging design is not only an art discipline, but more importantly, it is an engineering discipline. Therefore, it is necessary to intensify the packaging engineering idea, and to develop a design from the overall perspective of the system cycle, once the packaging product design proposal is confirmed, the organic cycle of the entire product is determined. The impact on the environment has become established. Therefore, the relevant environmental protection measures at the production, transportation and recycling stages must be considered concurrently in the design leading stage.
1) At the design stage, the market survey and material information are fully grasped, and a green packaging design scheme is put forward, which mainly includes: conception, design parameters, such as the volume and measurement value of the packaged goods, reserve capacity or allowable deviation parameters, and the selected packaging The materials are non-toxic, harmless, recyclable and recyclable. The selection of biodegradable, high-performance synthetic materials and native natural materials must take into account the relevant environmental factors; the design performance, including the shape and structure of the modeling style, graphics, text, and color To meet the aesthetic needs of green products, strict visual pollution. In the design stage, the entry of green packaging design is strengthened mainly from the selection of materials and the follow-up procedures of production.
2) During the production phase, it is necessary to fully consider how to improve the manufacturing process. The current research results show that the environmental load within each unit of measurement is directly proportional to the processing time, and the successful design strategy is how to shorten the processing time.
3) In the transportation stage, the design improvement of transport packaging should consider the attributes, characteristics, uses and transport modes of different commodities according to the hidden dangers of the products in the transportation process, reduce the energy consumption, and consider how to reduce the environmental impact of product packaging. load.
4) In the consumer phase, users are mainly considered...
5) In the recycling stage, firstly, it is necessary to consider how the packaging product can be easily recycled in the design process, and through the design of the structure and material, the disassembly and classification after the use is preset. The second is to consider how easily the packaging material can be recycled, because it is difficult to extract the pure material from the mixture, and the mixing of some materials cannot be separated. Therefore, the green rational allocation of materials must be considered in the design.
Second, green packaging design principles, methods Green packaging design must follow the principles of 3R1D, that is, reduce the consumption of packaging materials, packaging containers for refill use, packaging materials recycling recycling and packaging materials are degradable, but how to basic The ideological implementation in the conventional product design and development process, in order to form an overall pattern of a practical green packaging design process, is the key to the universal acceptance and application of green packaging design. Standardizing green packaging product design process mainly includes the following methods:
1. Function, considering the function of green packaging design, is mainly to make the use of the product more reasonable, the basic idea is to analyze the product's function 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. The structure analyzes the green packaging design from the morphological structure of the retired products, 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 Try to reduce the number of material types in the same packaged product so that they can be recycled.
3, cycle, from the packaging product's cycle to consider the green product design, to facilitate the entire product cycle cycle of resource consumption, environmental load for an overall description of human body design methods are:
1) Establish an operational framework for the packaging product cycle;
2) List the total consumption of packaging materials and assess the energy consumption in the state of raw materials;
3) Determine the energy consumption of packaging products during transportation and use, and determine the recycling rate of recycled materials in packaging products;
5) Determine the amount of final waste of the packaged product.
4. Evaluation: The constituent elements of packaging products and social ecological elements are the main evaluation index systems for green packaging design. The evaluation of the constituent elements of a product means:
1) Decompose the packaging product into relatively independent parts and briefly describe their manufacturing process;
2) Data analysis and assessment of the environmental problems and health damage conditions that may occur in each part of the production process;
3) Use special manufacturing processes for parts that may be subject to pollution problems, and replace the hazardous areas with rationalized product functions and structures. (To be continued)
