Since the 1990s, although plastic packaging materials have been subject to serious environmental challenges, but from the data published in recent years, plastic packaging is still one of the fastest growing demand materials in the packaging industry. According to the statistical analysis and prediction of the Freedonia Group of the United States, the average annual growth rate of paper and plastics in the packaging industry in the United States during 1996-2001 was 2.4%, of which 1.6% for paper and cardboard, and 3.4% for plastic. According to the statistical data of Japan's "Packaging Technology", Japan's 1997 sales of plastic packaging materials accounted for 15.4% of total sales of all types of packaging, still ranking second after paper and cardboard (57.5%). The remaining metals were 12%, glass 9.2%, wood products 5.2%, and other 0.7%.
According to the China International Packaging Exhibition, the total packaging output in China in 1997 was 18,300 kt, of which paper accounted for 52.6%, plastic accounted for 13.4%, metal accounted for 9.5%, and glass accounted for 38.8%. In 2000, the output of plastic packaging was forecast at 3250 kt, which was 25% higher than that of 1993.
According to the developments and predictions of the three major countries of the United States, Japan, and China mentioned above, it can be clearly seen that in the 21st century, plastic packaging materials will continue to grow steadily, and in the area of ​​packaging materials is still full of vitality, continuing to protect commodities and increase product value. Play an active role.
The 21st century is a century of environmental protection. Environmental issues are increasingly important. Resources and energy are becoming more intense. Plastic packaging materials will usher in new opportunities and will also face severe challenges. In order to meet the requirements of the new era, in addition to the requirements for increasing the packaging quality and efficiency of the market, plastic packaging materials are further required to be developed to save energy, save resources, be easily recycled or easily degraded by the environment. From the starting point of technology development, plastic packaging materials are moving toward high performance, versatility, adaptability to the environment, adoption of new raw materials, new processes, new equipment, and broadening the use of fields.
At the end of the 20th century, high-functionality, multi-functional plastic packaging materials became the hot-selling packaging material in many countries, and some products have been put into industrial production. These materials include high permeability, multi-functional preservation, selective permeability, heat resistance, sterility (antibacterial) and rust, deodorant, shape memory, resealable, easy to open and other plastic packaging materials Among them, the high-impervious multi-purpose fresh-keeping and aseptic packaging materials have been developed more rapidly and will become the focus of development in the early 21st century. In addition, nanocomposite packaging materials being researched and developed in recent years will receive more attention.
At the beginning of the 21st century, with the ever-increasing growth of the world economy and the continuous development of high technology, products are changing with each passing day. People's lives tend to be more convenient and leisure. Both the daily necessities packaging, food packaging and industrial packaging have higher requirements. On the other hand, With the growing demand for environmental protection, under the premise of satisfying the packaging function, the amount of waste generated is reduced as much as possible, and the development trend of lightweight, thin-walled packaging films, containers, and sheets is presented. The key technology is the active adoption of super toughness. It can process new materials that are thinner and easier to process, such as bimodal polymer HDPE, metallocene catalysts such as polyethylene, polypropylene and polystyrene, and plastic alloys, providing more raw material choices for plastic packaging. In particular, the development of polyethylene and polypropylene further improves many properties of flexible packaging structures such as toughness, transparency, barrier properties, heat resistance, and puncture resistance, and can reduce the heat sealing temperature, improve the processability, and improve Packaging line speed and so on. One of the characteristics of polyethylene food packaging film is that it can control the permeability of oxygen, carbon dioxide and water vapor, can be used for controlled atmosphere packaging, and greatly extend the shelf life of foods. Mainly used for supermarket semi-finished products such as salads, carrot slices, broccoli, and meat, as well as agricultural fresh-keeping bags and impermeability shrinking bags. It is estimated that by the year 2000, the capacity of such semi-finished products will increase from 3% in the mid-1990s to 25%, the sale of agricultural products in the form of fresh picking will reach 25%, and the demand for MPE controlled atmosphere modified packaging films will increase significantly.
Plastic composites, plastic alloys, and inorganic material-filled composite materials (ABC), which are hailed as tomorrow's Plastic Star, will be based on the development of the 20th century. Through joint efforts in both basic and applied research, production and processing technologies will Further progress will be made in the improvement and improvement of product performance, serialization, and functionalization, which will have greater impact on improving the quality, added value, and environmental suitability of plastic packaging as well as the development of new products.
With the improvement of the quality of plastic packaging products, the increase of functionality and the continuous development of new varieties, its use has also been further broadened. In particular, high-impervious plastic packaging materials have gradually expanded the scope of non-food packaging, including industrial Packaging, pharmaceutical packaging, agricultural and sideline product packaging, building materials packaging, and marine product packaging will all be further developed.
In the 21st century, the world economic restructuring continues to deepen and the transformation of the sustainable development strategy is the overall background of the world's industrial transformation. It is also the background of the changes in the environment of the plastics industry. Compared with traditional packaging materials, plastic packaging materials are evaluated from the entire life cycle of products. Energy conservation, resource conservation, reduction in waste generation, and lighter environmental load will lead to better opportunities for development in the early 21st century, and will continue to be one of the main application areas in plastics applications, and also in the packaging market. It will still occupy an important position and play an important role. However, a considerable part of plastic packaging materials is a one-time consumer product that is difficult to degrade in the natural environment after use. Therefore, it will continue to face severe challenges and tests if only from the perspective that its waste may cause environmental pollution.
In order to meet the needs of economic development, people's lives and markets, and at the same time adapt to the requirements of environmental protection, countries strengthen the research and development and the selection of environmental friendly plastic packaging materials and technologies, and actively study how to strengthen comprehensive treatment measures for their wastes. Measures.
At the beginning of the 21st century, technological advances in plastic raw materials, plastics processing, and plastics equipment and other industries improved product performance and improved; laws became more complete and management continued to improve, thereby ensuring the healthy and smooth development of the plastics industry, and demonstrating plastic packaging. The future of industry is even better.
Hotel Furniture
Hotel furniture refers to various types of furniture used in hotels, including hotel room furniture, public area furniture, restaurant furniture, etc. According to different functions and usage locations, hotel furniture can be divided into the following categories:
