Abstract
A process for making a hermetically sealed package, which includes forming a sheet of wrapping made of plastic material, in particular having a thickness of less than or equal to 140 μm. The process envisages: forming on the sheet a first, hollow, portion and a second, perimetral, portion, which delimits at least partially the first portion; inserting the product into the hollow portion obtained in the sheet of wrapping; applying a second sheet of wrapping in contact with the perimetral portion so as to close the hollow portion with the product inside; and welding the second sheet on the first sheet along the perimetral portion. Forming the first sheet includes providing on the second, perimetral, portion a series of pleats of the sheet, which are then sealed.
