Plastic bag (200) provided with a closing device (10) with a label with a tie that is joined in an integral way to an external face (210A) of the bag in correspondence of the curled part (202) for the purpose of allowing for an easy and effective tying. Said device (10) is divided into three sections: a first section (10A) in the form of a divisible end; a second section (10B) in the form of a liftable and knottable tie; a third section (10C) acting as an integral base. This device (10) is of a flexible material more resistant to traction with respect to the bag and has on its back, in correspondence of the second section (10B), a prevention layer (121) that locally covers the adhesive surface (120) in such a way as to allow for its lifting, tearing (113) and throttle knotting, also being automatically removable by friction in the realization of the permanent closure by means of said knotting. The invention, moreover, describes the production process of said bag (200). |
