Abstract
A method for wrapping a product in a sheet material wrapper employing a first sheet of plastically deformable sheet material (for example aluminium) and a second sheet of wrapping material (for example a plastic film) having springback. Once the product is placed on the first sheet, the second sheet is applied on the product providing in the second sheet a part wrapping the product and a part facing the first sheet. The first sheet and the part of said second sheet facing it are airtight-seal coupled so to form, by effect of the coupling, a plastically deformable composite sheet material against the product or to form an integral housing cup.

A method of wrapping a product in a wrapper of sheet material, the method comprising:
- forming a concave imprint in a first sheet of plastically deformable material;
- subsequent to forming the concave imprint, partially housing the product in the concave imprint in the first sheet;
- while the product is partially housed in the concave imprint in the first sheet, applying a second sheet of wrapping material exhibiting springback having larger dimensions than the first sheet onto said product to form in said second sheet a part having a dome shape and wrapping around said product and a part facing said first sheet,
- coupling said first sheet and the part of said second sheet facing said first sheet, so to form, through the coupling, a plastically deformable composite sheet material,
- shaping said plastically deformable composite sheet material forming a wrapper for said product, and
- folding the part of said second sheet facing said first sheet and coupled with said first sheet against said product.
