The appeal was the friendly shape of the blade: 5 to 7 inches long, with a rounded front edge and a boxier build than the typical chef`s knife, which usually stretches between 8 and 10 inches long and has a sleeker profile and a sword-like point. The style was developed for postwar Japanese home cooks as a more versatile alternative to vegetable cleavers- santoku reportedly means [three virtues," which are described variously as [meat, fish, and vegetables," or [chopping, slicing, and dicing"-and quickly became the country`s most popular Kitchen Knife.

Take the disposable snack box as one of the food packaging tools as an example. It has now become "white pollution" and has become a global public hazard. According to reports, China's railway transportation system uses more than 400 million foam plastic lunch boxes a year, and the recovery rate is only 16.6%, and the rest are thrown on both sides of the railway line, forming a "white pollution belt." In some serious conditions, the train was shocking. In order to recover and bury these lunch boxes and plastic bags, the Ministry of Railways actually spent 100 million yuan in 1994. Chemical experts point out that the polymer compound needs 200 to 400 years to be decomposed. Disposal or burial of such plastic products in the soil will impede the growth of crops. According to calculations, residual plastic containers, bowls, and membrane kilograms per mu of land can reduce corn production by 11% to 23%, wheat production by 10% to 6%, and bean production by 6% to 10%. The reduction in production is 15% to 60%. In recent years, hundreds of thousands of tons of waste plastic lunch boxes, bowls, membranes and plastic bags have been left in the country's farmland. Only the area of ​​plastic tableware used throughout 1994 can be covered in two years. A Singapore. These plastics were eaten by the animals. The lighter ones were sick in the digestive system and the others died. If it is burned, it releases a large amount of toxic gas. "White pollution" is polluting the living environment of human beings. Eliminating "white pollution" has become a hot topic in today's world. This year on June 25, is the 25th World Environment Protection Day. The theme of this World Environment Day is “developing green packaging for life on Earthâ€. It is precisely the specificization and in-depth development of this topic. There are four types of green packaging products on display at this time. First, internationally recognized environmental protection Materials such as BOPS longitudinal stretched polystyrene and its products, the second is the green packaging material pulp molding, the third is the paper lunch box and its production equipment, and the fourth is double degradable plastic products.
It can be seen that the problem of green packaging is an urgently resolved issue that has risen to global issues that need to be addressed. In foreign countries, many countries and regions have begun to move. They promulgated the rules, and actively use chemical technology to develop new types of decomposable plastics, or to use alternatives.
In Japan, traders who operate food have given up on plastic packaging, setting off a "green" revolution in the food industry and achieving greater success. Their food packaging is not only better and more practical. The need to care for the environment has also become an important issue for the packaging industry. Today's Japanese merchants try to use raw materials that do not pollute the environment when packaging food, and use paper bags instead of plastic containers. This also reduces the cost and technical difficulties of collecting the used packaging to the factory for recycling. Green packaging design Play a big role in this area. Many designers have made useful designs and have made gratifying achievements. Three reforms have been carried out, for example:
1 save material
A. The packaging designed and manufactured by Ajinomoto, Japan, can be said to have not displayed its glorious brilliance. Instead, it is made of white single-layered corrugated paper to make the most economical packaging, and label printing is also unpretentious;
B. Japan Shiseido Co., Ltd. launched packaging for high-efficiency shampoos and conditioners, demonstrating the power of its designers to carefully select packaging materials based on packaging capabilities. The whole set of design is far from the so-called "eye-catching packaging" originally seen, and its purpose is to reduce the use of materials as much as possible, thereby reducing the generation of garbage;
C. The packaging of Japanese bowls and dish cleaners can also take care of environmental protection needs. After the consumer has used the detergent for the first time, he can buy detergents sold in vertical or in bags, and then pour the detergent into the original plastic container to continue using it, so that the plastic container does not need to be discarded;
D. Ninety percent of Japan's milk is sold in creased lines. This is a good education. It allows children to contact and use environmentally-friendly “green†products since childhood. This kind of packaging that is easy to flatten is not only costly. Lower, and can reduce the footprint, ease to send to the cycle and reduce transportation costs. In addition, Yakltt, a popular Japanese drink, also uses a specially designed cup-shaped container with a tear-off bottom. After tearing the bottom, one can easily flatten the container for easy recycling. Every year in Tokyo, Japan, a packaging design contest is held. One award-winning drink package called Ecopac was widely used. Its packaging consists of a 100% recyclable cardboard box and a box containing a bag containing beverages. The so-called Bag in Carcon/Box design mainly aims to make it easier for people to separate the carton from the bag, and it is easier to handle when it is recycled. Most of the beverages and alcoholic beverages on the market in Japan use this kind of packaging. Another new packaging design that is beginning to be accepted by consumers is the standing bag/povch. Because opening a bag is easier than opening a bottle, the internal liquid Warm out, so the opening of the bag is specially designed for easy opening. This kind of bag is mainly used to replace plastic bottles. When comparing the two, the former uses only one-fifth of the plastic. In addition to drinks. Many Japanese cooking oils are sold in composite paper packaging, which greatly reduces the use of plastics.
The above are the excellent designs of several “green†packages that are commonly used in Japan. Most of them can reduce the difficulty of recycling. More importantly, they are beneficial to the maintenance of human health. Although paper containers have replaced plastic containers, the waste of packaging advertising is still a problem that cannot be ignored. If they are calculated by weight, they account for 20% to 30% of the total amount of waste. If they are calculated by volume, they account for 50% to 60% of the total waste. In view of this situation, Japanese experts pointed out that many have not packed necessary foods. Can give up completely

Commodity green packaging reform
At present, the vast majority of plastic products are used in almost all countries in the world to package food and pharmaceutical materials. What is worrying is that under certain media environment and temperature conditions, polymer monomers and some additives in plastics will be dissolved and transferred to foods and medicines in a very small amount, causing acute or chronic poisoning, and even serious It has a carcinogenic effect. At the same time, because the world consumes a lot of plastic products each year, they are thrown away into rubbish after use, and it is very difficult to rot, which also makes environmentalists wreck their brains.
