<p>The subject of the present invention is a multi-layer bag composed by thermoplastic layers joined with suitable adhesives and metallic layers with a barrier function, in which the total contact between reagents parts, which provoke the inflating action of the bag, it is obtained applying vacuum inside the multilayer bag, forcing the reagent system in a stable and fixed position, providing the inner gab which forms the reacting system, with a partial longitudinal or transversal welding which circumscribes the area of the bag where reaction must take place, realizing a preferential breakage side, ulteriorly inner to the reagent system, containing the reaction liquid element.</p> |
