A package comprising a tray-shaped bottom part (1) provided with an opening covered by a cover (2) being sealed to the bottom part (1) along a circumferential rim (10) so as to form a sealed compartment. With a view to forming a peelable cover part (15), the cover (2) is peelably sealed to the bottom part (1) along a portion of the rim thereof by means of a first sealing line. The first sealing line extends between two terminal points arranged on a line (23) extending across the opening of the bottom part (1). Moreover, the cover (2) is sealed firmly to the rim (10) of the bottom part (1) at least in the rim portions of the bottom part immediately adjacent said points by means of other sealing lines. At least in the portion of said line (23), the cover (15) is formed of a first flexible plastic sheet (14). The peelable cover part (15) is formed more rigid than the first plastic sheet (14) at least in the portion being furthest spaced apart from the connecting line (23) between the two terminal points.

Pour constituer une partie couvrante pelable (15), le couvercle (2) peut être fixé à la partie inférieure (1) d'une manière pelable suivant une portion du bord, par une première ligne de fixation hermétique. La première ligne de fixation hermétique s'étend entre deux points terminaux disposés sur une ligne (23) traversant l'ouverture de la partie inférieure (1). En outre, le couvercle (2) est fixé hermétiquement et solidement au bord (10) de la partie inférieure (1), au moins dans les portions de bord de la partie inférieure jouxtant immédiatement lesdits points, au moyen d'autres lignes de fixation étanche. Au moins dans une portion de ladite ligne (23), le couvercle (15) est formé d'une première feuille plastique flexible (14). La partie de couvercle pelable (15) est réalisée pour être plus rigide que la première feuille plastique (14) au moins dans la portion qui est la plus éloignée de la ligne de liaison (23) entre les deux points terminaux.
