Among the four major packaging materials: paper, plastic, metal, and glass, paper packaging materials are the cheapest, and can be recycled and reused, which is conducive to environmental protection, and therefore develops the fastest.

Usually, what we discuss most is the development status and trends of the domestic paper packaging industry. This article will analyze the development trends and trends of the international paper packaging industry for you. Based on relevant information, the author believes that the international paper packaging industry mainly presents the following development directions.

The packaging process tends to be simplified

The application of modern technology in the field of packaging has simplified many packaging processes and made them more scientific and reasonable. For example, in the past, plastic packaging extrusion, hot pressing, stamping and other forming processes have gradually been used in the forming of cardboard packaging, so that the products that could not be packaged in paper in the past also use paper packaging.

Packaging post-printing processing technology is more scientific and practical, and packaging performance and effects have also undergone significant changes. For example, the waxing and laminating process in the packaging surface treatment in the past has been gradually replaced by surface glue (gluing treatment), and the anti-counterfeiting packaging production process has shifted from partial printing or production to integral large-area printing and production .

Intelligent paper packaging machinery

At present, in order to meet the diversified needs of modern commodity packaging, developed countries have begun to continuously develop general packaging machinery and equipment that adapt to multiple varieties and small batches. At the same time, it keeps up with the pace of contemporary high-tech development and develops and develops modern special-purpose packaging machinery that applies high-tech.

Including blown film machinery, composite machinery, coating machinery, slitting machinery, printing machinery, paper bag machinery, can filling machine, etc. This kind of machinery occupies a small space, high efficiency, and the appearance of the machinery is adapted to the environmental requirements and the psychological requirements of the operators. Wait. Packaging and printing equipment is developing towards digitization and miniaturization, and the cost also tends to be lower.

Nano new material packaging industrialization

The latest nano-technology has industrial application prospects in the packaging field: nano-plastic new materials, environmentally friendly colored nano-film, nano-composite polymer fresh-keeping film, new nano-composite color-changing anti-counterfeiting film and heavy ion microporous anti-counterfeiting technology, modified poly Lipid nano PET container, polymer nano composite material.

In addition, nano antibacterial coatings (nano organic, inorganic antibacterial, sterile packaging), applications of nano materials in temperature sensitivity, gas sensitivity, and humidity sensitivity, nano inks and nano pigments (transparent nano-scale slow iron oxide), Nano-magnetic printing, nano-paper and other packaging materials also have high industrial application prospects.

Micro-type corrugated board becomes a trend

In recent years, with the in-depth research on the miniaturization of corrugated board, in the international market, especially in Europe, a kind of micro-corrugated board material used to replace thick board is in the ascendant. The tendency of layered corrugated cardboard to replace thick cardboard is particularly violent.

With the development and use of this kind of micro corrugated board, on the basis of ensuring the protection and storage functions of the corrugated board in the traditional sense, its role in product sales and display has also been further strengthened.

The production of micro-corrugated machinery does not require brand-new changes to the original corrugated equipment. At present, fine corrugated paper boxes and fine paper boxes have largely replaced the original packaging paper boxes and paper boxes used in tobacco and alcohol, food, household products, medicine, computers, clothing, cosmetics, detergents and other products.

Micro-corrugated paper containers have the advantages of low price, firmness and flatness, and light and thin materials. They have begun to rapidly occupy the domestic and foreign markets, and the annual growth rate in my country has exceeded 10%.

The price of fine corrugated is lower, and its cost is reduced by about 30% under the same use demand; the fine corrugated is firm, smooth and beautiful, has good printing performance, and saves about 30% of raw paper. The carton processing machine and the drum die cutting machine do not need to be replaced, it can be processed on the latest drum die cutting machine with vacuum conveying equipment, and even on the flat plate die cutting machine.

Green packaging materials

With the rising awareness of environmental protection, the global economy and industrial system are emerging with the concept of "zero packaging" and "green packaging" led by the packaging revolution, and they will be implemented, and green products and green packaging will become hotspots.

Green packaging is a high-tech form of packaging. From raw materials, to packaging design and manufacturing, to product use and recycling, every link must be resource-saving, efficient, and harmless. Ecological packaging materials have received extensive attention from the world, and their research should be considered from the entire process of development, design, production, use, and disposal.

In addition, paper product packaging focuses on the development of low-weight, high-strength, and lightweight high-end paper packaging to achieve the goal of standardization, serialization, multiple varieties, multiple substrates, and multiple uses.

Implement circular economy

Circular economy is an economic growth model that takes the efficient use of resources as the core, low consumption, low emissions, and high efficiency as its basic characteristics, and conforms to the concept of sustainable development. It is a tradition of "mass production, large consumption, and large waste". A fundamental change in the growth model of a resource-based economy.

After the new concept of circular economy was put forward by the Americans in the 1960s, it quickly received high attention from industrialized countries. Germany and Japan successively formulated the "Circular Economy Law" at the end of the 20th century to promote circular economy under the legal system. The international community has listed circular economy and knowledge economy as two major trends in world economic development.
