Abstract
A pack contains a dry alkaline solid (1), which produces in an aqueous media a pH value exceeding 10, which consists of at least a one-layer packaging and which contains at least one polymer film (3) soluble in aqueous alkaline media. The polymer film contains two phases, whereby the continuous phase is made of a copolymer or terpolymer of .alpha.-.beta. unsaturated monocarboxylic acid which has a COOH group and the discontinuous phase is formed by a polymer which has an epoxy group, whereby both polymers are bonded in the boundary layer through esterification between COOH groups of the copolymer or terpolymer and epoxy groups of the discontinuous phase polymer.
