Corrugated board is a wide range of green packaging materials , inexpensive , lightweight compression, etc. , the market has been favored . Corrugated boxes are made ??of corrugated cardboard slotting , creasing , folding , bonding step . As transport packaging containers , corrugated boxes should have the ability to resist deformation and failure to meet the need of the protection of the logistics of goods , carton production before its compressive strength is estimated . However , the strength of the corrugated box design rely mainly on experience , the lack of scientific theoretical study has important practical significance , so its compression performance . The compressive strength of corrugated boxes depends on the compression performance of corrugated board and carton structure . Firstly, the raw material test analysis , determination of tissue paper 160g/m2 , 105g/m2 paper core ring crush strength and elastic modulus of corrugated board , corrugated boxes Strength lay the foundation . Departure from the principle of structural mechanics , corrugated boxes broken down into the flat cardboard structural elements , and in the the existing corrugated board structure and mechanical model based on the analysis of the mechanical properties of corrugated board , the establishment of the control equation of the corrugated plate bending problem . Analysis of all edges simply supported non- corrugated carton to resist damage by the carrier edges superimposed the corner elastic critical buckling load constraint factor rectangular corrugated board , corrugated boxes mechanical model , derive the compressive strength of corrugated boxes formula . Theoretical analysis and experimental verification , in the size range of commonly used box type , corrugated box compression model can better predict the compressive strength with height , aspect ratio trend , but the compressive strength of surrounding the theory predict trends test trends there are some deviations, the model has yet to be further amended . The subject of the corrugated box compressive strength calculations provide a theoretical basis to reduce the empirical and roughness of the design process , and has a certain significance and practical value .
