The resealable packaging of claim 1, wherein the supporting insert does not extend within the container aperture. 3. The resealable package of claim 1, wherein the lower portions are situated below the head portions and at a distance from the container aperture. 4. The resealable package of claim 1, wherein the free edges of the top panels are substantially shorter than the width (m) of the lateral margins. 5. The resealable package of claim 1, wherein the top panels have four sides, three of them being linked to head portions of the frame. 6. The resealable package of claim 1, wherein the lower peripheral free edge of the frame defines the widest inner cross section of said frame, at least for an initial configuration. 7. The resealable package of claim 1, wherein at least one of the front, rear, and end walls includes a hinged panel forming longitudinal, movable portions and the lower peripheral edge of the frame further comprises the longitudinal, movable portions in addition of the foot portions. 8. The resealable package of claim 1, wherein the supporting insert is made of double face corrugated board. 9. The resealable package of claim 1, wherein the supporting insert is made from a single sheet like insert blank assembled by mutual engagement of tabs. 10. The resealable package of claim 1, wherein the flexible container extends along a longitudinal axis (X) between opposite side end faces having a sealing seam, and wherein the closure flap extends in a transversal direction (T) with respect to said longitudinal axis (X), the container aperture having width (w) along the longitudinal axis which is comprised between 60% and 90% of the top face length (I). 11. The resealable package of claim 10 wherein the width of the container aperture is about 70% of the top face length. 12. The resealable package of claim 1, wherein the supporting insert contains a stack of a flat food products having a longitudinal widest outer section which substantially corresponds to the inner cross section of the lower peripheral edge of the frame, at least for an initial configuration. 13. The resealable package of claim 1 wherein the frame further comprises sloping panels connecting the top panels and the front and rear walls. 14. The resealable package of claim 1 where the top panels do not extend into the container aperture. 15. The resealable package of claim 1 wherein the frame has no bottom wall and the lower peripheral edge thereof is a free edge. 16. The resealable package of claim 1, wherein the lower portions are separated from the container aperture by a greater distance than the distance by which the free edges of the top panels are separated from the container aperture. 17. The resealable package of claim 1, wherein the flexible container extends along a longitudinal axis (X) between opposite side end faces having a sealing seam, the sealing seams being separated from the end walls.
