Looking at the latest trends in packaging technology from Tokyo International Packaging Exhibition

At the end of 2000, the Japan Packaging Technology Association (Chair: Takahashi Tatsuki) successfully hosted the "2000 Tokyo International Packaging Exhibition." At the once-a-year event in the packaging industry, 556 companies from Japan and abroad have introduced a variety of exhibits, from raw materials to machinery and equipment, processing technology and logistics machinery. Here, according to the clues of each company's exhibits, we will explore new trends in the development of the packaging industry's technology. First, the increasing use of resources Reusable In the past 2000 years, Japan began to implement the "Container Packaging Recycling Act", "environmental economic law", from the height of the law to identify the specific containers, packaging manufacturers and users Both of them have the obligation to recycle and reuse the containers and packaging. Therefore, we have seen in this exhibition that there are a large number of eco-friendly and environment-friendly products in the exhibits. Moreover, since paper containers are easier to recycle than metal and plastic products, companies have developed fiercely in the development of the former products. competition. Prince Paper Co., Ltd. has developed a waterproof, moisture-proof corrugated paper to replace packaging materials made of foamed plastic to complete the packaging and transportation of fresh food. Manufacturers use mainly water-repellent raw materials in the core of the corrugated paper, and apply a certain agent on the surface of the corrugated paper to make it waterproof without water seeping directly into ice cubes. Since this type of corrugated paper is not treated with paraffin or a stamper at all, it can be directly recycled as waste paper after use. In addition, it is also Oji Paper Co., Ltd. that the waste paper is reshaped according to the shape of the object to which it is applied and used as a buffer and fixing material after drying. Because of its simple technology for recycling, and at the same time it can meet the needs of reducing product weight and compressing costs, it can be as small as fruit packaging and as large as electrical product packaging. This kind of fixed material made of waste paper has a wide range of uses. Space is seen by the industry as another way to improve the remaining issues of waste paper. On the Other hand, paper containers can't be used to hold oils, chemicals, etc. The common practice now is to use polypropylene and polyethylene materials to make plastic containers, and then put paper labels on them. If this is done, when these containers are recycled, they must first be separated from the containers themselves, which undoubtedly adds a lot of trouble. To solve this problem, Prince Okubo Synthetic Paper Co., Ltd. has developed new products that are easy to recycle. It uses synthetic paper, which uses polypropylene as its main raw material, as a label paper. This synthetic paper also has the dual characteristics of film and paper. Therefore, it not only has excellent water, oil, and chemical resistance, but also can be attached to a plastic container, etc. like a paper label, and it is no longer necessary to peel it off from the container when it is recycled. It can be recycled together. Reuse. Second, the digital trend In addition to the eco-friendly, environmentally friendly products, the exhibition reflects the trend of digital packaging design, plate-making exhibits can be found everywhere. In order to shorten the production period, reduce costs, and simplify the process, the packaging industry is not only continuing to pay attention to digital machinery equipment such as DPT, but also to meet the needs of certain special orders, and to achieve the versatility of special printing paper such as transparent tape for flexible packaging. It also shows special attention to color correction. A color printer named MICROLINE7050c was exhibited at the exhibition. Although it is only a printer for packaging, in order to obtain a realistic effect, manufacturers have expanded their output lines to 190 lines, and have the ability to handle 12 color inks including impervious colorless, white ink. . In addition to the printed paper, it can also be printed on special transparent tape. The company that developed the above-mentioned printer also launched the inkjet software RIP "BESTColor" for processing ICC files at the exhibition. Previously due to the special color used on the packaging, data correction software was not very easy to use, but more and more companies saw its development prospects and actively considered the performance of the printer and its color management system. Introduced. In addition, in order to reduce production costs, advertisers and other parties have already had more and more companies themselves mastering the technology of implementing color correction on inkjet printers. This trend will become more apparent in the future.
