Abstract: | This paper deals with the characterization of creep properties and recoverability of double-wall corrugated paperboard with
A and B flutes at different combined conditions of the ambient temperature 20°C with four kinds of relative humidities and
five kinds of constant compression loads. The main feature of this paper is the evaluation on the creep properties and recoverability
of double-wall corrugated paperboard with A and B flutes by a series of experimental studies on creep testing apparatus, the
analysis of effects of relative humidities and constant compression loads on creep properties and recoverability, and the
establishment of mathematical model of creep and time curves. By using Method of the Least Square and Method of Nonlinear
Regression, the piecewise experimental formulas of creep and time curves have been obtained. The work provides basic data
and introduces important mathematical relationships relevant to design applications for protective packaging for transportation
and storage of goods. |
