The invention relates to air-tightly packed products whose fragrance is an essential characteristic. In the case of such products, it can be desirable to provide the actual packaging with the fragrance of the product in order to give the consumer an initial impression of the fragrance. To this end, the invention provides a method for fragrancing packaging. According to the inventive method, perfume oils and/or aromatic oils are mixed with a dispersion which is solid at room temperature, at a high temperature. Said dispersion contains at least one polymer and at least one carboxylic acid salt. The mixture is applied to the packaging at a temperature of at least 50 DEG C and at most 85 DEG C, the mixture having a maximum viscosity (shearing rate = 100 s<-1>) of 10000 mPas at this processing temperature. A suitable preparation for fragrancing packaging in this method contains 0.1 to 60 wt. % perfume and/or aromatic oil and 1 to 20 wt. % carboxylic acid salt and polymer, water and optionally, other auxiliary substances. |
