AQUEOUS COLD SEAL ADHESIVE |
摘要 |
Described is an aqueous cold seal adhesive in the form of an aqueous polymer dispersion comprising a mixture of a first polymer and a second polymer, wherein the first polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of C1 to C20 alkyl (meth)acrylates and has a glass transition temperature of less than 0°C; and wherein the second polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of vinylaromatics having up to 20 C atom, and has a glass transition temperature of at least 50°C. Also described are cold sealable coated polymer films coated with the aqueous cold seal adhesive and a method for producing a cold-sealed pack by applying the aqueous cold seal adhesive to a packaging substrate. |
