The present invention relates to a packaging material in the form of a composite comprising at least one paper or cardboard support applied atop which there are at least one paper coating slip layer, if appropriate a print layer, if appropriate one or more thermoplastic layers and if appropriate one or more further layers, wherein at least one of the applied layers comprises microencapsulated latent heat storage material and the capsule wall of the microencapsulated latent heat storage material is constructed from <tables id="TABLE-US-00001" num="00001"> <table frame="none" colsep="0" rowsep="0"> <tgroup align="left" colsep="0" rowsep="0" cols="3"> <colspec colname="offset" colwidth="14pt" align="left"/> <colspec colname="1" colwidth="56pt" align="left"/> <colspec colname="2" colwidth="147pt" align="left"/> <thead> <row> <entry/> <entry namest="offset" nameend="2" align="center" rowsep="1"/> </row> </thead> <tbody valign="top"> <row> <entry/> <entry>10% to 100%</entry> <entry>of one or more C1-C24-alkyl esters of acrylic</entry> </row> <row> <entry/> <entry>by weight</entry> <entry>acid and/or methacrylic acid (monomers I),</entry> </row> <row> <entry/> <entry>0% to 80%</entry> <entry>of a difunctional or polyfunctional monomer</entry> </row> <row> <entry/> <entry>by weight</entry> <entry>(monomers II) which is insoluble or sparingly</entry> </row> <row> <entry/> <entry/> <entry>soluble in water, and</entry> </row> <row> <entry/> <entry>0% to 90%</entry> <entry>of other monomers (monomer III),</entry> </row> <row> <entry/> <entry>by weight</entry> </row> <row> <entry/> <entry namest="offset" nameend="2" align="center" rowsep="1"/> </row> </tbody> </tgroup> </table> </tables> based in each case on the total weight of the monomers, to a process for producing it, and to its use for packaging foodstuffs. |
