1. A closure member for a food container, comprising:
a multilayer laminate peripherally delimited by a peripheral edge having a shape suitable for covering an opening of a corresponding container and defining a hand gripping portion for a user; the multilayer laminate comprising:
a first layer made of a material at least partially light permeable;
a second layer;
a third layer made of a repositionable adhesive material interposed between the first layer and the second layer;
an anti-adhesive strip is-interposed between the first layer and the second layer and placed near the hand gripping portion;
an inner weakening line defined on the second layer and extending according to a geometry defining, in use, an access gap to the container;
an outer weakening line, defined on the second layer, proximal to the peripheral edge with respect to the inner weakening line at least at the hand gripping portion and placed at the anti-adhesive strip.
