With the rapid development of international trade, the circulation of goods has become more frequent, and the requirements for protective packaging in the transportation of goods have become higher and higher. Not only does the packing of packaging boxes guarantee that the goods will not be damaged during the circulation, but also Packaging materials are green materials. Paper packaging materials are recognized as packaging materials for environmentally friendly packaging boxes and are widely used in the transportation of goods for their superior protection and cushioning properties. Among paper transport packaging materials, corrugated paperboard and cartons are the most widely used. Corrugated paperboards have good cushioning properties for small loads, but their strength is relatively low. They can not withstand the heavy impact load of heavy-duty products. Honeycomb paperboard has higher strength. , Can resist large loads, but due to too much rigidity, the cushioning for small loads is not good. Therefore, this paper combines corrugated paperboard with honeycomb paperboard to study its production process technology, trial production of corrugated-honeycomb composite structure paperboard, and through a series of static compression test and drop impact test to study its buffering performance, in order to expect a corrugated-honeycomb composite. The practical application of structural cardboard provides a theoretical reference. Corrugated-honeycomb composite structure paperboard is a new kind of structural paperboard. This article has made research and discussion on its production technology and buffering performance. Firstly, the structural characteristics of the corrugated-honeycomb composite structure paperboard were analyzed, the production process method was discussed, the mechanical properties were analyzed by the sandwich layer theory, the stress-strain relationship was obtained, and the honeycomb paperboard and A corrugated paperboard combination with different thicknesses were selected. , Made of corrugated-honeycomb composite structure cardboard samples, static compression test, test data obtained, draw the stress - strain curve, and then converted into a buffer coefficient curve, analysis of its static buffer performance. Whereas buffer packaging materials are mainly used in transport packaging, static buffer tests are sometimes not sufficient to reflect actual conditions of transport conditions. Drop impact testing machines were used in this study to perform drop impacts on corrugated cardboard, different thicknesses of honeycomb paperboard and corrugated-honeycomb composite structure paperboard. Test, draw test data, draw the maximum acceleration - static stress curve, and then convert it into a buffer coefficient curve, analyze its dynamic buffering performance. Based on the theoretical research on the static buffering performance and dynamic buffering performance of corrugated-honeycomb composite structure paperboard, this paper applies it to the design of buffer packaging for flat glass, selects a flat glass product, performs buffer packaging design, and analyzes each of them. The advantages and disadvantages of the design scheme. The results of the study indicate that corrugated-honeycomb composite structural paperboards have good mechanical properties and cushioning properties compared to those used alone with corrugated paperboard or honeycomb paperboard or other cushioned containers. Under small loads, corrugated-honeycomb composite structures The main manifestation of cardboard is the cushioning performance of corrugated cardboard. Under larger loads, it exhibits mainly the cushioning properties of honeycomb paperboard. Therefore, the use of different specifications of corrugated-honeycomb-composite cardboard as the packaging material for the transport packaging box, especially in the heavy product transport packaging has a broad application prospects.
