A generally planar sealed beverage sachet comprising, a product which provides a beverage when mixed in an aqueous medium, a substantially air- and water-impermeable sheet material defining opposing panels sealed to each other by a seam along an upper portion of said sachet, a pair of side seams and a base seam to enclose said product which is contained therein, a web of material adhered to both of said opposing panels of said sheet material between said side seams and between said base seam and the upper portion of said sachet, said base seam being a self-opening, pressure sensitive seal which is automatically releasable thus allowing the base seam to open upon a liquid medium being introduced into the sachet under pressure through said upper portion above said web, said web material being water permeable and having a seam whose apex points toward said upper portion of said sachet with said product being disposed on the upper portion of said web material, and said web material when viewed in cross-section having an inverted, upwardly directed generally V-shaped portion of web material free from adherence to said opposing faces of said sheet material and configured to provide an assist to the opening of said base seal by everting downwardly towards said base seam upon introduction of said pressurized liquid medium through said upper portion above said web.
