Among the four packaging materials of paper, plastic, metal and glass, paper packaging materials are cheap and can be recycled and reused, which is beneficial to environmental protection and therefore develops rapidly. What we usually discuss is the development status and trend of the domestic paper packaging industry. This article will analyze the development trends and trends of the international paper packaging industry. Based on comprehensive information, the author believes that the international paper packaging industry mainly has the following development directions.
First, 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. For example, in the past, the molding process of extrusion, hot pressing and stamping of plastic packaging has gradually been used to form the packaging of cardboard packaging, so that products that could not be wrapped in paper in the past were also used in paper packaging.
The post-printing process is more scientific and practical, and the packaging performance and effects have also undergone significant changes. For example, in the past, the wax coating and laminating process in packaging surface treatment have been gradually replaced by surface glue (spraying treatment), and the anti-counterfeiting packaging process has been changed from partial printing or production to integral large-area printing and production. .
Second, the intelligence of paper packaging machinery
At present, in order to meet the diversified needs of modern commodity packaging, developed countries have begun to develop universal packaging machinery and equipment that can adapt to multiple varieties and small batches. At the same time, it keeps pace with the development of modern high-tech and continuously applies advanced technology. Develop and develop modern special-purpose packaging machinery that uses high technology. Including blown film machinery, compound machinery, coating machinery, slitting machinery, printing machinery, paper bag machinery, can filling machine, etc., this type of machinery occupies small space, high efficiency, mechanical appearance adapts to environmental requirements and operator psychological requirements Wait. Packaging and printing equipment is becoming more digital and miniaturized, and the cost is also cheaper.
Third, nano-new material packaging industrialization
The new nanotechnology has industrial application prospects in the packaging field: nano plastic new materials, green environmentally friendly colored nano film, nano composite polymer plastic wrap, new nano composite discoloration anti-counterfeiting film and heavy ion microporous anti-counterfeiting technology, modified poly Lipid nano PET containers, polymer nanocomposites, nano antibacterial coatings (nano-organic, inorganic antibacterial, aseptic packaging), nano-materials in temperature sensitive, gas sensitive, moisture sensitive applications, nano-inks and nano-pigments (transparent nano Graded slow iron oxide), nano magnetic printing, nano paper and binary nano interface packaging materials.
Fourth, the trend of fine corrugated cardboard
In recent years, with the deepening of the research on the miniaturization of corrugated cardboard, in the international market, especially in Europe, a kind of micro corrugated cardboard material used to replace the thick cardboard is in the ascendant, especially the Fæ¥ž and Gæ¥ž. The trend of layer corrugated cardboard instead of thick cardboard is particularly strong. With the development and use of this kind of micro corrugated cardboard, on the basis of ensuring the protection and storage function of the corrugated cardboard in the traditional sense, its role in the sales display of goods has been further strengthened. Machines that produce miniature corrugations do not require new changes to the original corrugated equipment. At present, fine corrugated boxes and fine cartons have largely replaced the original packaging cartons and cartons used in tobacco, alcohol, food, household goods, medicine, computers, clothing, cosmetics, detergents and other products.
The micro-corrugated paper container has the advantages of low price, firm and flat, and light and thin materials. It has begun to quickly occupy the domestic and international markets, and its annual growth rate in China has exceeded 8%. The price of fine corrugated is lower, and the cost is reduced by about 30% when the usage demand is the same; the fine corrugated board is firm, flat, beautiful, and the printing performance is good, saving about 30% of the original paper. The carton and drum die-cutters do not need to be replaced, they can be machined on new drum die-cutters with vacuum conveyors, and even on lithographic die-cutters.
Fifth, the packaging materials are green
With the rising awareness of environmental protection, the global economy and industrial system are emerging with the concept of â€œzero-packageâ€ and â€œgreen packagingâ€ led by the packaging revolution, and the implementation of green storage and green packaging will become a hot spot.
Green packaging is a high-tech packaging. From the beginning of raw materials, to the design and manufacture of packaging, to the recycling of products, every link must be sourced and harmless. Ecological packaging materials have received wide attention in the world, and their research should be considered from the whole process of development, design, production, use, and disposal. In addition, paper product packaging focuses on the development of low-weight, high-strength, lightweight paper packaging, achieving the goal of standardization, serialization, multi-species, multi-substrate, and multi-purpose.
Sixth, implementing a circular economy
The circular economy is a kind of traditional resource that takes resources utilization as the core, low consumption, low emission, and basic characteristics, and conforms to the concept of sustainable development. It is a traditional resource of â€œmass production, mass consumption, and a large amount of wasteâ€. The fundamental change in the model of economic growth. The new concept of circular economy was put forward by the industrialized countries in the United States after it was proposed in the 1960s. Germany and Japan successively formulated the Circular Economy Law at the end of the 20th century to promote the circular economy with the legal system. The international community has listed the circular economy and the knowledge economy as two major trends in world economic development.
