The invention relates to a reactive pressure-sensitive adhesive film with (a) a polymeric film-forming matrix, (b) one or more reactive component(s) in a proportion by mass of at least 30% by weight, based on the sum of components (a), (b) and (c), and (c) a reagent selected from an initiator, in particular free-radical initiator, or a hardener or an activator, wherein the polymeric film-forming matrix is at least 50% by weight a crystallizable polymer which, on cooling, starting from a temperature that is at least 30 K above the peak temperature of the melting peak, but is at least 100 °C, has a crystallization enthalpy of less than 1 J/g at a cooling rate of 10 K/min in differential scanning calorimetry (DSC). |
