First, the mainstream of future packaging design
Packaging design has entered the computer age. The traditional packaging design method is slow to adapt to the highly competitive commodity economy due to its slow design speed and poor accuracy. Nowadays, the cycle of a new product from development to market is getting shorter and shorter, and the structure and form of packaging are becoming more diversified. Sometimes, in order to adapt to different regions and different consumer groups, a product needs to have various forms of packaging. From creativity, color, specifications, materials to production methods, there must be different requirements. Therefore, in order to grasp the market opportunities in a timely manner, it is necessary to quickly design the packaging products required by the market by means of advanced means. Packaging designers must also know the relevant packaging manufacturing process, how to select materials, how to use modern packaging manufacturing equipment, such as prepress process equipment, postpress processing equipment.
In short, the future packaging design is more to use the existing packaging and product packaging patterns, to choose and make a reasonable combination, rather than the traditional packaging design, from the beginning to the idea, from scratch. Drawing and combining are the mainstream of future packaging design. The appreciation of the designer is the key to the success of the packaging design.
Second, the packaging process tends to be simplified
Modern technology is used in the packaging field, which makes many packaging processes simpler and more scientific and reasonable.
The packaging process mainly refers to the manufacturing process in the packaging manufacturing process. The development of the packaging process is realized by the development of related science. For example, the molding process of packaging, the bonding process of packaging, the printing process of packaging, and the finishing process of packaging have all undergone an improved process. The packaging molding process includes the molding of metal packaging, the molding of plastic packaging, the molding of paper packaging, and the molding of other composite packaging. Among them: in the past, plastic packaging extrusion, hot pressing, stamping and other molding, has gradually used the formation of paper packaging; the past cardboard cardboard packaging embossing (concave) molding is more difficult, and now has been basically solved; plastic foam molding The technology has been widely used for the foaming and molding of paper-mold packaging products, so that products that cannot be packaged in paper in the past are also used in paper packaging.
The post-printing process is more scientific and applicable, and the packaging performance and effects have undergone significant changes. For example, the waxing and laminating process in the past packaging surface treatment has been gradually replaced by surface glue (spraying treatment) because the surface gloss of the wax coating is not good; and the single-sided coating in the coating film is easy to make The packaging product is warped and deformed, and the double-sided coating brings certain difficulties to the cutting of the subsequent process.
The packaging drying process is also turned from ordinary hot baking to ultraviolet curing, making dry forming more energy efficient, fast and reliable.
The packaging and printing process is more diverse. Especially for the packaging and printing of high-end goods, screen printing and four printing have been adopted. There is also a production process for anti-counterfeiting packaging, which has been turned from partial printing or production to integral large-area printing and production anti-counterfeiting.
Third, the packaging machinery is intelligent
The packaging machinery market is highly competitive. It is a fast-growing category of China's packaging industry, and together with food machinery has developed into one of the top ten categories of China's machinery industry.
The general trend of packaging machinery development: At present, the characteristics of packaging machinery tend to be "three high" - high speed, high efficiency and high quality. The development focus tends to low energy consumption, light weight, compact structure, small footprint, high efficiency, adaptability to the environment and the psychological needs of operators, and environmental protection needs.
The development trend of foreign packaging machinery is: it reflects the high-tech of modern advanced packaging machinery, especially the packaging machinery and equipment produced by countries such as Europe, America and Japan with advanced technology and economy. Its technology is accompanied by the development of technology and commodity economy. leading position. In recent years, in order to meet the diversified needs of modern commodity packaging, developed countries have developed multi-variety and small-volume general packaging technologies and equipment, while keeping pace with the development of high-tech, constantly applying advanced technologies, developing and developing high-tech applications. A modern, specialized packaging machine for technology. The new technologies applied are: aerospace industry technology (heat pipe), micro-electricity technology, magnetic technology, information processing technology, sensing technology (photoelectric and chemical), laser technology, biotechnology and new processing technology, new Mechanical components (such as tapered synchronous belt drives, etc.), new fiber materials, etc., make a variety of packaging machinery more intelligent.
The development trend of domestic packaging institutions is: on the basis of introduction, digestion and absorption, with certain innovations, the technological content of products is also constantly improving. These packaging machinery products are developing in the direction of electromechanical integration, main and auxiliary machinery, and complete sets of connection. . There are some problems in the development of packaging machinery products in China, mainly how to face the competition of foreign enterprises and foreign-funded enterprises, how to improve the "three-oriented" level of products according to China's national conditions, to achieve high-speed work, diversification of packaging product specifications, and improvement Reliability and how to make food and Pharmaceutical Packaging machinery sterile. Under the premise of improving the performance and reliability of packaging machinery products, we will move toward mechatronics and control microcomputers. Using advanced design methods such as reliability design, optimization design and computer-aided design, we will develop advanced machinery and components (parts) such as combined and modular, improve the technological level of the products and the level of “three-orientedâ€, and at the same time, with the international quality system. Combine and vigorously develop various automatic detection technologies and equipments that are compatible with packaging machinery. At present, China's packaging machinery is compared with advanced developed countries. Some processing technologies and some components still have gaps. Some key materials still fail to meet the requirements. Therefore, this aspect will be the future of China's packaging machinery field. Key breakthroughs and solutions.
Third, the replacement and update of packaging materials
The quality of the packaging depends largely on the performance of the packaging material. Without a good packaging material, it is impossible to have a good packaging product. Packaging new materials and packaging new technology is the primary pursuit of packaging companies or research institutes. Now many new products and new processes must have new packaging materials to match them, in order to achieve a good packaging effect.
Based on environmental protection requirements, packaging materials that pollute the environment against environmental protection need to be updated. New types of packaging materials are being developed, and some have achieved initial success. There are mainly the following major categories:
1. Plastic packaging represented by EPS snack boxes will be replaced by new paper packaging.
In many places, due to the hazards of plastic packaging waste, plastic packaging such as EPS snack boxes, which are difficult to recycle and handle, has been restricted. The state has issued documents to list them as the key packaging products to be replaced. New packaging produced from pulp and plant fiber has emerged as the times require, and has been promoted by the state as one of the key promotion projects. The alternative EPS packaging products also include Eppl packaging liners.
2. Plastic bag packaging materials are moving towards soluble, non-polluting materials.
Many cities have banned the use of ultra-thin plastic bags (packaging), so plastic packaging materials that do not pollute the environment are in urgent need of research and development. Such as composite plastic film in composite materials, various surface coatings and the like. Advances in research on new materials that can replace existing plastic packaging materials, such as water-soluble plastic films and other types of degradable plastic films, have begun to be applied, especially as some foreign companies are targeting China's huge market. For example, some Japanese companies have begun to seek partners in China to establish joint ventures to produce soluble plastic film.
3. Wood packaging is looking for alternative packaging materials.
Because the United States and other Western countries use the "Tianniu" in the wood packaging of China's export products as an excuse to limit the export of China's products, all products that are packaged in wood must be treated with special special treatment or replaced with other materials. Due to cost and other issues, even the use of heavy-duty corrugated boxes is not competent, so at present China is already tackling the problem, it is recommended to replace with honeycomb cardboard boxes, but must solve the problem that the box can withstand gravity and loading and unloading strength.
4. Other new types of auxiliary packaging materials are also urgently needed for research.
Such as adhesives, surface treatment agents, inks, and the like. Many of China's carton packaging consumes a large amount of paper, high cost, and low strength, because the quality and performance of these auxiliary packaging materials cannot meet the requirements. In the aspect of packaging printing inks, environmentally friendly inks (or green inks) have been popular in the world. China is also developing vigorously. For example, Zhuzhou Institute of Technology and Senko Group have developed several multifunctional water-based inks, which have been mass-produced. The user responded well after use.
Fourth, packaging and processing integration
Many new packaging technologies are based on new packaging thinking. The new thinking of packaging is to detach the existing packaging technology and products, and apply other related technology combinations to the packaging to form new packaging technology. There are several types of technologies in this area:
1. Packaging curing technology - curing and drying energy updates, from heat to light;
2. Packaging and cutting technology - new cutting and forming equipment;
3. Packaging and processing combined technology - packaging and processing combined;
4. Packaging function borrowing technology - packaging function exceeds packaging, value-added;
5. Packaging function protection technology - add functional ingredients such as fresh-keeping, sterilizing, moisture-proof, anti-static, anti-odor and other ingredients into the packaging materials.
In addition to the above five aspects, there should be other technologies, such as packaging technology for living fresh materials (packaging of living packaging). In addition, with the advent of new packaging materials, some of the techniques in the packaging process have also undergone new changes. For example, since the appearance of the stretched stretch film, the processes of wrapping, shrinking, and bundling are integrated, and the operation is simplified and quick.
The most promising of the above is the packaging and processing technology. It solves many treatment processes and directly borrows the packaging mechanism to realize the integration of packaging and processing, making the packaging more potential and effective.
5. The packaging industry must have industry support
The development of packaging industrialization is achieved through the combination of technology and products to increase market share in the market. The packaging industry of the future must have characteristics and scale. Like Tetra Pak, it is the world that dominates the world with its features and technology. With the emphasis on environmental protection, the recycling of packaging will result in a new industry for packaging, which will have a faster development.
The packaging industry must rely on the industry, backed by equipment and technology, and take the road of grouping. Many packaging companies founded or co-founded by cigarette factories, cosmetics factories, pharmaceutical factories, wineries, etc. have good product quality and economic benefits, because they have industry support and a stable market.
Specialization and technological innovation are the magic weapon for the packaging industry to remain invincible in the competition. The technology-oriented packaging industry, such as professional canning factory, Bottle making factory, capping factory, new packaging material factory, etc. The greater the development, the typical representative of this type of packaging industry.
