Abstract

A method for manufacturing a block bag of thermoplastic material with at least one filling valve from a tubular foil part having bottom flaps and at least one corner flap forming the valve being longer than the bottom flaps, wherein the bottom flaps are folded around a heat isolating piece and the stack of foils forming the bottom are heatsealed together by applying heat from both sides of the stack.
