Abstract
A description is given of the use of a polymer dispersion for cold sealing, the polymer dispersion comprising a polymer in dispersion in water and having a glass transition temperature in the range from −20 to +10° C., said polymer being preparable by emulsion polymerization of radically polymerizable monomers in the presence of at least one polymeric protective colloid, and the polymer being formed to an extent of 0.05 to less than 1 wt % of a monomer M, selected from the group consisting of (meth)acrylate monomers having a substituent of the formula where X is CH, O, NH or NR, and R is a C1 to C4 alkyl group. Descriptions are also given of a method for producing cold-sealed packaging, and of the packaging obtainable by said method.
