Typical case of Japanese packaging reduction

A few days ago, Shanghai Baoxie received a delegation from the "Packaging and Environmental Protection" delegation of the Japan Association for Packaging. Sino-Japanese packaging experts exchanged views on packaging, packaging waste, and environmental issues, and conducted in-depth discussions on issues that are currently plaguing social and economic development. Discussions and discussions. At the meeting, Japanese experts briefed their Shanghai counterparts on their advanced experience in product packaging reduction. There are many cases worth learning from and learning from. The stones of other mountains can be used to attack jade.

First, Sony's new packaging of electronic products

Sony promotes the company's product packaging based on the four principles of "Reduc, Recycle, Replace". Not only do they follow the "3R" principle of "reducing, reusing, recycling" and recycling economy, but they are also looking for alternatives to improve product packaging. Let's look at a few examples. In 1998, the company improved the foam packaging material of large-sized television sets, and used eight small EPS material-divided packaging to buffer and prevent earthquakes, reducing the use of 40% EPS (see Figure 1); Some products use EPS material in front of them, corrugated board materials are used at the back, and corrugated paperboard boxes with special shapes are used on the outer packaging to save resources (see Figure 2). In addition, pulp molding materials are used instead of the original EPS for small-sized TV sets. Materials (see Figure 3).

Second, the new packaging of Dainippon Printing Co., Ltd.

The company's product packaging implements the four principles of environmental awareness, namely the principle of reducing packaging materials, reducing the volume of packaging after use, recycling, and reducing environmental pollution.

(1) The principle of reducing the amount of packaging materials shall be: reducing the thickness of the container, thinning the film, reducing the number of layers, and changing the packaging material;

(2) The principle of reducing the volume of packaging after use is: box groove, indentation on the surface of cardboard box, change of packaging materials and other methods. See the product case (Figure 4). After using this bottle, the volume becomes very small and convenient. Recycling;

(3) The principle of recycling: For example, the use of easy-to-separate paper containers, plastic film inside the carton, after use, paper, plastic separation, waste reduction, aspects of treatment, the case shown in Figure 5; there is an easy to separate Thermoformed containers, see Figure 6 for examples.

(4) Principle of reducing environmental pollution: The company will improve the materials, processes, and other aspects of packaging products, reduce carbon dioxide (CO2) emissions during production, and protect the environment.

Third, packaging products of Toyo Tin Co., Ltd.

Toyo Ultimate Can, a plastic-metal composite tank developed by Toyo Tank, is a two-piece can made of PET and iron. The main target is a beverage can. This composite tank saves material and is easy to recycle. It has low energy consumption and low consumption in the production process and is an environmentally friendly product (see Figure 7). Toyo can also develops and produces an ultra-light glass bottle. The thickness of a 187 ml milk bottle made from this material is only 1.63 millimeters and 89 grams in weight. The thickness of an ordinary milk bottle is 2.26 millimeters and weighs 130 grams. It is 40% lighter than an ordinary bottle and can be reused more than 40 times (see Fig. 8). The company also produces paper cups without wood fibers (see Figure 9) and biodegradable paper-plastic cups. To make cans and bottles of plastic containers easy to handle and reduce their volume after use, Toyo cans are designed with several circular creases on the plastic barrels. When they are discarded, they can be easily folded and reduced in size. These types of plastic barrels (bottles) are as many as 500 ml to 10 liters volume and other species (see Figure 10).

From the actual cases of packaging products of the above Japanese companies, we can clearly see that Japanese counterparts have done a lot of fruitful research and development on packaging reduction. The Fifth Plenary Session of the 16th CPC Central Committee proposed that the development of a circular economy and the building of a resource-conserving, environment-friendly society be regarded as a major strategic task for the "Eleventh Five-Year" economic and social development. The National Development and Reform Commission pointed out that leaders have pointed out some problems in the rapid development of the packaging industry in China. First, many companies have not escaped the extensive business model of high input, high consumption, high pollution, and low output; some products have an excessive packaging phenomenon; second, there is a low recovery rate of packaging materials, such as PET bottles and beverage cans. The recovery and utilization are better. The recycling rate of other types of packaging is relatively low. Third, the waste of resources is serious. In addition to increasing the burden of municipal solid waste disposal, a large number of waste packaging materials also waste a lot of resources; The existing recycling channels for packaging materials are relatively chaotic. The original recycling systems and channels relying on a single government behavior are not smooth. The standardized recycling network based on the market has not yet been established. The fifth is the backward technology of packaging materials recycling and resources. The recycling rate is low, and there is a more serious secondary pollution. The existence of these problems is not only inconsistent with the requirements of the central government for building a resource-conserving, environment-friendly society, but also restricting the development of the packaging industry.

We must vigorously promote the green packaging of sustainable development strategies in the entire packaging industry, and require that the design, manufacture, use, and disposal of product packaging should meet the requirements for ecological protection such as low consumption, reduction in quantity, and less pollution. Under the condition of satisfying the functions of protection, convenience, sales, etc., appropriate packaging should be adopted with the least amount of use. The packaging material must be non-toxic and harmless, and should be easily reused, or its waste should be easily recycled. Changes in materials require changes in the processing technology, processing machinery, container manufacturing, packaging design, decoration, printing, and other aspects, which has led to a major change in the entire packaging industry and the technological revolution. Therefore, following the principle of recycling economy and achieving reduction in packaging, the packaging industry in China responds to the requirements of the Party Central Committee and the State Council to take the building of a resource-saving and environment-friendly society that is incumbent on the historical task. We must start from our own companies, start from now, and work together to build our country into a green home.
