In the packaging industry, packaging corrugated cardboard, as an important packaging material, is favored for its unique structure and performance. However, with the continuous changes in the market and the increasing demand of consumers, how to ensure the strength of packaging corrugated cardboard while achieving light weight has become the focus of attention inside and outside the industry.The high strength of packaging corrugated cardboard mainly comes from its unique corrugated structure. The corrugated corrugated paper formed by corrugating rod processing and noodle paper are bonded to form the basic structure of packaging corrugated cardboard. This structure enables packaging corrugated cardboard to absorb and disperse energy through the deformation of corrugation when subjected to external force, thereby improving the compression, burst resistance and flat compression strength of the cardboard. At the same time, the strength of packaging corrugated cardboard can also be optimized by adjusting the shape, size and number of layers of corrugated cardboard.However, high strength does not mean that light weight can be ignored. While pursuing strength, light weight is also an important direction for the development of packaging corrugated cardboard. Lightweighting can not only reduce transportation and storage costs, but also reduce carbon emissions and meet environmental protection requirements. In order to achieve lightweighting, we can start from multiple aspects such as material selection, structural optimization and production process.In terms of material selection, lightweight and high-strength raw materials can be used, such as high-strength fiber raw materials and environmentally friendly adhesives, to improve the strength of cardboard and reduce weight. At the same time, new degradable materials can also be considered to achieve more environmentally friendly packaging.In terms of structural optimization, the strength of cardboard can be improved by improving the shape and size of corrugated paper, while reducing the amount of material used. For example, using a finer corrugated shape can reduce weight while ensuring strength. In addition, lightweighting can be achieved by optimizing the number of layers and arrangement of cardboard.Advances in production technology also make it possible to lightweight packaging corrugated cardboard. For example, the use of advanced production equipment and technology can improve production efficiency and the quality stability of cardboard, thereby reducing scrap rate and material waste. At the same time, an intelligent production management system can be used to accurately control the production process to achieve a more precise lightweight design.The emergence of environmentally friendly high-strength packaging corrugated cardboard has pushed the perfect combination of high strength and light weight to a new height. This kind of cardboard not only has high mechanical strength, can withstand collisions and falls during transportation, and better protect the safety of the items in the package, but also because of its light weight and high strength, it helps to achieve lightweight packaging design, reduce transportation energy consumption and reduce carbon emissions.In summary, the high strength and light weight of packaging corrugated cardboard are not contradictory, but can be perfectly combined through innovations in material selection, structural optimization and production processes.
