The hottest Henan successfully developed corrugate

Henan has successfully developed the corrugated box local composite and fiber strengthening technology

in mid September, the builders learned that a technology called corrugated box local composite and fiber strengthening technology has been successfully developed by Henan Dayong industrial Yuceng company and is now being put into practical application

according to the introduction, the flat compressive strength of the packaging cartons using this technology Northcote expects that the use of such materials and technologies in refrigerators that will be launched next year has increased by 55%, the strength of the main pressure bearing surface for experiments that need to be done in high temperature environments has increased by 40%, the overall compressive strength has increased by 30%, and the drop strength has increased by 25%. Because the six sides of the traditional corrugated box are corrugated cardboard with the same number of layers and thickness, if you want to increase the strength, you can only increase the gram weight or the number of layers of the paper. For parts that do not need to be enhanced, such as the bottom and surface of the box, the increased gram weight and layers are a waste of functions. The corrugated board local composite and fiber strengthening technology just solves the contradiction between improving the strength of the whole box and reducing the weight and number of layers of paper. Local compounding and fiber strengthening is to compound the main pressure bearing surface of the carton and then carry out fiber strengthening. The specific process route is to first cut the roll paper according to the carton specification, compound each layer with adhesive, dry it and enter the corrugated board production line for local compounding, and then strengthen the fiber. According to the company's analysis, using corrugated board local composite and fiber strengthening technology to produce packaging cartons of the same specification and strength can save 20% - 60% of the cost. Another problem with this new technology is that the investment mechanism is not perfect. The company has applied for a national patent
