摘要：
Method for producing diecuts from heat-activatable adhesive films which comprises applying a layer of heat-activatable adhesive material to a carrier material having a glass transition temperature at least 20° C. lower that that of the adhesive, laminating the heat-activatable layer onto a release liner at a temperature between the glass transition temperature of the release liner and heat activatable adhesive and then diecutting the heat-activatable adhesive layer on the release liner.
