So-called green packaging refers to the ability to recycle reuse, recycling or degradation, conservation of resources and energy and packaging reduction, and packaged products throughout their life cycle (from the materials, machining to waste disposal) caused pollution on human health and the environment are not the proper packaging. To develop green packaging materials, extensive green packaging is of special significance, become the inevitable choice in the development of packaging around the world, will become the inevitable trend in the development of the packaging industry. Specification for green packaging design process has the following methods:

1, structure

From negligent morphology analysis on green packaging design of products, mainly to make the structure more scientific and practical and beautiful. In this sense, first carefully identify the basic concept of product properties, and under the framework of the improvement of the environmental impacts of products, analysis of product function structure during the design process, but also to examine material structure. In terms of function:

(1) the overall structure and function analysis of packaging design, weighing whether to merge related functions or reduce the number of attachments, whether the most rational use of materials.

(2) clear packaging product shape and volume range, category, property, transport and analysis annex of the main structure, function or functions of packaging products, and further the use of packaged products.

(3) it also saves material and reduce the size and weight. In terms of structure:

1) overall analysis of product materials and disassembly, use of results;

2) properties of the packaging material uses a reasonable allocation of the packing;

3) try to reduce the number of materials in the same packaging products, to recycling.

2, the function is

Functional consideration on green packaging design, primarily in order to make the intended use of the product more reasonable, the basic idea is detailed analysis of product function to determine what is the most basic of features to further assess these functions consume less material and energy, and have a minimum load on the environment. The design process is:

(1) an assessment on each functional unit of material and energy consumption, based on theoretical and practical analysis of the measured parameters, to study whether these features can use less materials and energy consumption to achieve;

(2) to quantify the ability to define product value, basic of identity corresponds to the value of parameter;

(3) against packaging specific features set out its objectives and on the theory and practice of measurement parameters;

(4) new packaging products and reference products, optimize new product design and development strategies.

3, evaluation

Packaging elements of ecological and social factors is evaluation index system of green packing design. Evaluation of the product elements refers to:

(1) there may be part of the pollution problem to take special manufacturing process, also the rationalization of product function and structure to replace part of harmful pollution.

(2) decomposition as a relatively independent part of the packaged products, a brief description of their manufacturing process.

(3) for each part of the production process may generate environmental problems and impairment of health data analysis and assessment of the situation.

Evaluation of ecological factors mainly refer to:

(1) property index refers to green packaging products, the consumption of energy efficiency indicators such as energy consumption and recycling. In view of the above assessment and indicators, on the one hand with reference to the existing environmental protection standards, industry standards and evaluate the relevant policies and regulations. On the existing products and related technology as a reference, by contrast to evaluations.

(2) environmental attributes, namely packaging product safety cycle and environment-related indicators, including indicators of atmospheric pollution, contamination indicator, indicator of solid indicators of pollution and noise pollution.

(3) resource attributes, that is used in the product cycle of material resources, design resources, information resources, and human resources indicators.

4, cycle

From packaged products consider green product design cycle, throughout the entire product cycle of resource consumption, environmental load as a general description, the body design is:

(1) a packaging framework of operation of the production cycle;

(2) determination of packaged products in the transportation and use of energy, determination of recycled material in packaging recycling;

(3) lists the total consumption of packaging materials to assess the State of the energy consumption of raw materials;

(4) determination of final number of waste packaging products.

Promote green primary green packaging design of packaging, it has a direct impact on packaging, packaging materials selection and use and packaging waste processing. Green packaging design is we in ensure products function of premise Xia, find a best of meet points, seeks to makes products packaging of design and using more reasonable, in products packaging design original, on should is packaging design guarantee function of while as reduced using of material, as elimination not necessary of decorative and extra of packaging, advocates simple packaging, to save resources, maximum of protection natural resources, minimum number of generated waste, as reduced on environment of pollution.
