Beschreibung
Zusammenfassung:	A process for producing a sheetlike formulation comprising at least one single-layer active substance matrix for the controlled release of active substance to the vicinity of the application site, the active substances being selected from crop protection agents, biocides, fertilizers, plant strengtheners, cosmetic active principles and fragrances, is characterized in that the matrix is produced using at least two layers (1, 2), identical in composition, of a base material in the following temporally and spatially separate steps: - provision of two prefabricable layers (1,2), identical in composition, of a base material, - application of active substance to at least one of the two layers (1,2), - placement of the two layers (1,2) atop one another so as to enclose the active substance applied, and irreversible joining under pressure to form a laminate, - storage of the laminate for predeterminable duration under defined conditions, with migration of the active substance into the base layers (1,2), and connection at their interfaces to form a homogenous matrix featuring substantially uniform dispensation of active substance.
