World Packaging Technology and Industry (I)

With the rapid development of science and technology and increasingly fierce market competition, commodity packaging has become an important means to promote sales and enhance competitiveness. Many new technologies, new processes, and new ideas have been applied in packaging design, packaging technology, packaging equipment, new packaging materials, and new packaging industries.
First, the trend of packaging design Packaging design has entered the era of computerization. The traditional packaging design methods and methods no longer adapt to the fiercely competitive commodity economy era. A design method based on computers and various information systems that is suitable for updating and replacing has emerged. This is because the traditional design methods are slow in design and have poor accuracy, making it difficult to adapt to the relative surplus of commodities and fierce market competition. Today's designers must have the basic skills of packaging design, but more importantly, they think, appreciate, and understand ideas. Computer technology is based on the aforementioned skills. How to use computers and various design software, such as color blocks, Floppy disks, such as patterns and logos, combine them modularly. Packaging designers must also know the relevant packaging production process, how to choose materials, how to use modern packaging manufacturing equipment, such as prepress processing equipment, post-press processing equipment.
Computer and packaging software are the main hardware for future packaging design. Leaving these two kinds of hardware to design the packaging, the efficiency will be very low. The appreciation of designers is the key to the success of packaging design. No appreciation, no matter how good the design and conditions are, it is difficult to design good packaging products.
Second, the development of packaging technology Modern science and technology used in the packaging field, making a lot of packaging technology to simplify and more scientific and reasonable.
The packaging process mainly refers to the manufacturing process in the packaging manufacturing process, and its development is achieved through the development of related sciences. For example, the packaging molding process and packaging decoration (finishing process) have all undergone a process of improvement.
The molding of the package includes molding of metal packages, molding of plastic packages, molding of paper packages, and molding of other composite materials. Plastics packaging, such as extrusion, hot pressing, stamping and other molding, has been gradually used in the formation of cardboard packaging, cardboard carton packaging in the past convex (concave) molding is more difficult, and now has been basically resolved. Many different materials have been packaged with the help of air pressure, impact, wet processing, vacuum technology to simplify and scientific process.
Plastic foam molding technology has been widely used in the foaming and molding of paper mold packaging products, so that products that cannot be packaged in paper but must be plastic are also used in paper packaging, so that packaging waste no longer pollutes the environment .
The packaging and printing process is more scientific and applicable. Packaging performance and effects are continuously improving. For example, past wax coating and film coating processes in the packaging surface treatment have gradually been replaced by surface gluing (spray-bonding) because of the poor surface gloss of the wax coating and the film coating. For one-sided film coating, it is easy to cause warping deformation of the packaging products, while the use of double-sided film coating makes the cutting of subsequent processes difficult.
The packaging and drying process also turns from ordinary heat drying in the past to UV curing, making it more energy-efficient, fast, and reliable for drying.
The packaging printing process is also more diverse. In particular, silk screen printing and gravure printing have been adopted for packaging and printing of high-end products.
There are also anti-counterfeiting packaging manufacturing techniques, which have been turned from partial printing or production to integral large-area printing and production of anti-counterfeiting.
In summary, packaging technology is the fastest growing, fastest-changing, and most versatile technology. The advanced technology is an important guarantee for a well-made packaging product. Therefore, the packaging process is also a content that many manufacturers compete for research and block each other.
Third, the development of packaging equipment Packing equipment packaging machinery, its fierce market competition, the prospects are very broad. It is the fastest-growing category in China's packaging industry. Together with food machinery, it has become one of the ten categories of China's machinery industry.
The general trend of the development of packaging machinery, various high and new technologies, new institutions, and new control methods have been continuously applied. At present, the characteristics of packaging machinery tend to be "three highs": high speed, high efficiency, and high quality. The focus tends to be energy-saving and consumption-reducing, reliable quality and performance, advanced automatic control level, good stability, light weight, compact structure, small footprint, low noise, high efficiency, appearance and appearance adapting to the environment and psychological requirements of operators, which is beneficial to Environmental protection and so on.
The development trend of foreign packaging machinery reflects the high-tech level of modern advanced packaging machinery, especially packaging machinery and equipment in Europe, the United States, Japan and other countries with advanced technology and economy. Its technology is accompanied by the development of science and technology and commodity economy, and it is at the leading position in the world. status.
In recent years, on the one hand, in order to meet the diversified needs of modern commodity packaging, developed countries have developed universal packaging technologies and equipment adapted to multi-variety and small-batch production; at the same time, they have closely followed the pace of contemporary high-tech development, and continuously applied advanced technologies, development and Development and application of high technology, development and development of modern high-tech special-purpose packaging machinery. The new technologies applied include: aerospace industry technology (heat pipe), microelectronic technology, magnetic technology, information processing technology, sensing technology (optoelectronics and chemistry), laser technology, biotechnology, and new processing technology, new Mechanical component structures (such as tapered synchronous toothed belt drives, etc.), new fiber optic materials, and so on, have made many packaging machines more intelligent.
