Effect of Clearance between Top Panel of Containers and Contents on Compression Strength Loss of Corrugated Containers for Food Products during Warehousing

Abstract

Mathematical model was studied on the compression strength characteristics of corrugated containers with contents in the previous papers.That was C = B + αD···(1), C =βA…(2). Coefficient β involved above equation (2) meant the compensation factor for the compression strength loss of corrugated containers during warehousing. In this paper βcharacteristics study of corrugated containers filled with carton boxes is made on the effect of clearance between the top panel of corrugated containers and carton boxes by using 2-tier model. Study is made on compression creep failure tests conditioned at 20℃.,65%RH/40℃.,90% RH. Results indicate the optimum range of top clearance for minimizing compression strength loss of corrugated containers filled with carton boxes. Continued on the previous paper significant route to the optimum design for the compression strength of corrugated contain­ers is provided by using this new results.
