• This paper addresses fold lines induced by a wrapping fold of a large space membrane to realize the high packaging efficiency. Details of the fold lines are examined by performing wrapping fold experiments. The experimental results indicate that the fold line induced by the wrapping fold deviates from the target fold line, and the deviation of the fold line decreases the packaging efficiency. The configuration of the induced fold line is identified analytically, where the deformation of the crease induced by the wrapping fold is considered. The relationships between the configuration of the induced fold line and the mechanical parameter of the wrapping fold, which are the tensile force and the bending stiffness, are determined by the theoretical analysis. The relationships are verified by comparing with the experimental results. Based on the fold line obtained by the theoretical analysis, a fold pattern is proposed to avoid the deviation of the fold line. Finally, the high packaging efficiency is realized by using the proposed fold pattern.
