The invention relates to a pouch (10; 10') comprising :
- an inner pouch (20) comprising a bottom surface (22) and opposite side walls (24) extending upwardly from the bottom surface (22), said opposite side walls (24) being associated to each other along at least one peripheral edge (24a, 24b, 24c) thereof, thereby delimiting a product-filling area (A); and
- a pair of outer films (30), each overlying a respective one of said opposite side walls (24) of the inner pouch (10), said outer films (30) being associated to each other through a first seal (21, 23) at said at least one peripheral edge of the inner pouch (20); The outer films (30) are further associated to each other through a second seal spaced apart from the first seal (21, 23) with respect to the product-filling area (A), thereby at least one inflatable chamber (34, 34') filled with an inert gas being delimited, between said first seal (21, 13) and second seal (31, 33; 31', 33'). The invention further relates to a method of forming a pouch (10; 10'). |
