Abstract: A package is made of a cardboard blank with crease lines and has wall panels (1), bottom flaps (2) forming a bottom of the package and top flaps (3), namely short-side flaps (3A) and long-side flaps (3B), folded and heat sealed together to form the top of the package. One of the long-side flaps has at its free end a seal tab (4), which is provided with a heat seal adhesive and is sealed against the opposite long-side flap. The seal tab has a smaller length than the width of the package for enabling it to be brought down into the top of the package for reclosing thereof.
