Packaging Industry Development Trends - Four Features

â–² Packaging design tends to diversify

Flash Jichang, vice president of the China Packaging Technology Association, said that packaging design has entered the computer age. Traditional packaging design methods have been unable to adapt to the highly competitive commodity economy due to their slow design and poor accuracy. Today, the period from development to market entry of a new product is getting shorter and shorter, and the packaging structure and form are becoming increasingly diversified. Sometimes a product needs to be packaged in various forms to suit different regions and different consumer groups. There are different requirements from creativity, color, specifications, materials, and production methods. Therefore, in order to grasp market opportunities in a timely manner, it is necessary to rapidly design packaging products needed by the market with advanced means. 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.

In short, the future of packaging equipment is more to use the existing packaging and packaging patterns, to choose between, and a reasonable combination, rather than the traditional packaging design, like to start from scratch, start from scratch.

Reference and combination are the mainstream of future packaging design. The appreciation of designers is the key to the success of packaging design.

â–² The packaging process tends to be simplified

Flash Yanchang said that modern technology has been applied to the packaging field, which has made many packaging processes easier 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 achieved through the development of related sciences. For example, the packaging molding process, the bonding process of the packaging, the printing process of the packaging, and the finishing process of the packaging all undergo a process of improvement. The molding process of packaging includes metal packaging, plastic packaging, paper packaging, and other composite packaging. Among them, in the past, plastic packaging, such as extrusion, hot pressing, stamping and other molding, has been gradually used in the formation of paper packaging; past paperboard cardboard packaging convex (concave) molding is more difficult, and now has basically been resolved; plastic foam molding Technology has been widely used for foaming and forming of paper-type packaging products, so that paper packaging cannot be used for products that cannot be packaged in the past.

The packaging and printing treatment process is more scientific and applicable, and the packaging performance and effects have undergone significant changes. For example, waxing and laminating processes in the past for surface treatment of packaging have been gradually replaced by surface gluing (spray processing). This is due to the poor surface gloss of the wax coating, and the single-sided film in the film can easily cause warpage of the packaging product. The use of double-sided film coating brings certain difficulties to the subsequent process cutting. The packaging and drying process has also been turned from ordinary heat drying to ultraviolet light curing, making the drying process more energy-efficient, fast, and reliable.

The packaging and printing process is more diversified. In particular, packaging printing for high-end products has adopted screen printing and four printing. There are also anti-counterfeiting packaging production processes, which have been turned from partial printing or production to integral large-area printing and production anti-counterfeiting.

â–² Packaging machinery tends to be smart

According to Niu Changchang, packaging machinery is the fastest growing category of packaging industry in China and, like food machinery, has become one of the ten categories of China's machinery industry.

The general trend of the development of packaging machinery: The current characteristics of packaging machinery tend to "three high" - high speed, high efficiency and high quality. The focus of development tends to be low energy consumption, light weight, compact structure, small footprint, high efficiency, appearance and appearance adapting to the environment and psychological needs of operators, and environmental protection requirements.

The trend of the development of foreign packaging machinery is to reflect the high and new technology of modern advanced packaging machinery, especially the packaging machinery and equipment produced by science and technology and economically developed countries such as Europe, America and Japan. Its technology is accompanied by the development of science and technology and commodity economy. International leader. In recent years, in order to meet the diversified needs of modern commodity packaging, developed countries have developed multi-variety, low-volume, general-purpose packaging technologies and equipment, while keeping pace with high-tech development, continuously applying advanced technologies, and developing and developing high-tech applications. Modern technology-specific packaging machinery. The new technologies applied include space technology (heat pipe), microelectronics, magnetics, information processing, sensing (optoelectronics and chemistry), laser technology, biotechnology and new processing technologies, new machinery Component structures (such as tapered synchronous toothed belt drives, etc.), new fiber optic materials, and so on, make a variety of packaging machinery tend to be intelligent.

The development trend of domestic packaging institutions is that based on the introduction, digestion, and absorption, certain innovations have been made, and the scientific and technological content of products has also been continuously improved. These packaging machinery products are being developed in the direction of electromechanical integration, integration of main and auxiliary machines, and connection of complete sets. There are some problems in the development process of China's packaging machinery products, mainly how to face the competition of foreign companies and foreign-funded enterprises, how to improve the level of product "threeizations" according to China's national conditions, achieve high-speed work, diversification of packaging product specifications, Improve reliability and how to make food and medicine packaging machinery sterilize; under the premise of improving the use performance and reliability of packaging machinery products, go to electromechanical integration and control computerization; use reliability design, optimization design and computer-aided design Advanced design methods such as modular and modular advanced machinery and components (parts) are developed to improve the technological level of the products and the "three levels"; at the same time, they are combined with the international quality system to develop various types of packaging machines. Automatic detection technology and equipment. At present, compared with advanced developed countries in terms of packaging machinery in China, there are gaps in certain processing technologies and certain components, and some key materials do not meet the requirements. Therefore, this aspect will be a key breakthrough and solution for the future of packaging machinery in China. |

â–²The packaging material tends to be solubilized

Flash vice president believes that the quality of the packaging depends largely on the performance of the packaging material. There can be no good packaging products without good packaging materials. Packaging new materials and packaging new technologies are the primary pursuit of packaging companies or research institutes. Now many new products and new processes must have new packaging materials in order to achieve good packaging results. Based on environmental requirements, packaging materials that are environmentally unfriendly are urgently updated. New types of packaging materials are being developed, and some have achieved initial success, mainly in the following categories:

First, the plastic packaging represented by EPS snack boxes will be replaced by a new type of paper packaging. In many places due to the hazards of plastic packaging waste, such as EPS fast food boxes, such as the amount of large, difficult to recycle and handle the plastic packaging has been limited, the state has issued a document to be listed as a key to replace the packaging products. The new type of packaging produced from pulp and plant fibers came into being and was listed as one of the key promotion projects by the state. Replacement EPS-type packaging products also include Eppl industry packaging liners.

Second, plastic bag packaging materials are moving toward soluble, non-polluting materials. Many cities have banned the use of ultra-thin plastic bags (packages), so the environment-friendly plastic packaging materials urgently need to be researched and developed, such as composite plastic films in composite materials, various surface coatings, etc.

Some researches on new materials that can replace existing plastic packaging materials have made progress. For example, water-soluble plastic films and other biodegradable plastic films have begun to be applied. In particular, some foreign companies are targeting large Chinese markets. For example, some Japanese companies began to seek partners in our country to establish joint ventures to produce soluble plastic films.

Third, wood packaging is seeking alternative packaging materials. As the United States and other Western countries use the “Cattle” as an excuse to find wood products in Chinese export products, and restrict the export of Chinese products, any products that use wood packaging must undergo complex special treatment or be replaced with other materials. Due to the cost and other issues, even heavy-duty corrugated boxes are difficult to handle. Therefore, at present, China has been working on a problem, and instead of using a honeycomb cardboard box, it is necessary to solve the problem of gravity and handling strength that the box can withstand.

Many packaging technologies are based on new packaging ideas. Packaging new thinking is to detach existing packaging technologies and products, and apply other related technology combinations to packaging to form new packaging technologies. There are several major categories of technologies in this area:

Packaging and Curing Technology - Renewing Curing and Drying Energy, From Heat to Light; Packaging Cutting and Forming Technology - New Cutting and Forming Instruments; Packaging and Processing Combined Technology - Packaging and Process Integration; Packaging Functional Borrowing Technology - Packaging Functionality Exceeds the packaging, has the value-added function; The packaging function protection technology - In the packing material adds the freshness, the sterilization, the dampproof, the static electricity, guards against the odor and so on the functional ingredient.

In addition to the above five aspects, there are other technologies, such as packaging technology for fresh produce (packaging for living packages). In addition, with the emergence of new packaging materials, some new changes have also occurred in the packaging process. Such as the emergence of dry stretch film, so that wrapping, shrinkage, banding and other processes into one, the operation is simplified and fast. The most promising of these is the packaging and processing technology. It solves a lot of processing technology, directly borrows the packaging mechanism, realizes the integration of packaging and processing, and makes packaging more potential and effective.
