Abstract ­ The packing of elastic sheets is investigated in a quasi two-dimensional experimental
setup: a sheet is pulled through a rigid hole acting as a container, so that its configuration is
mostly prescribed by the cross-section of the sheet in the plane of the hole. The characterisation
of the packed configuration is made possible by using refined image analysis. The geometrical
properties and energies of the branches forming the cross-section are broadly distributed. We find
distributions of energy with exponential tails. This setup naturally divides the system into two
sub-systems: in contact with the container and within the bulk. While the geometrical properties of
