| abstract |
The invention relates to a recloseable packaging having a cold sealed adhesive layer that can be reclosed after the packaging is opened, wherein the adhesive layer comprises a polymer in emulsion made of at least 60 wt% of main monomers selected from the group made up of C1 to C20-alkyl(meth)acrylates, vinyl esters of up to 20 C atoms comprising carbolic acids, vinyl aromates having up to 20 C atoms, ethylene unsaturated nitriles, vinyl halogenides, vinyl ethers of alcohols comprising 1 to 10 C atoms, aliphatic hydrocarbons having 2 to 8 C atoms and one or two double bonds, and mixtures of said monomers, wherein the polymer in emulsion can be produced by means of emulsion polymerization of radically polymerizable monomers in the presence of at least one protective colloid. The invention further relates to aqueous polymer dispersions suitable for producing the packaging according to the invention, and to polymer films coated with the polymer dispersion. |
