BINDER COMPOSITION FOR HEAT-SEALABLE FILM COATINGS

Provided herein is a binder composition for heat-sealable film coatings including from 10 to 65 weight-% of a polymeric binder. The polymeric binder includes, as monomers, keto- or aldehyde containing monomers, monoolefinically unsaturated monomers, and copolymerizable surfactants. The monoolefinica...

Zusammenfassung:	Provided herein is a binder composition for heat-sealable film coatings including from 10 to 65 weight-% of a polymeric binder. The polymeric binder includes, as monomers, keto- or aldehyde containing monomers, monoolefinically unsaturated monomers, and copolymerizable surfactants. The monoolefinically unsaturated monomers contain less than 0.4 weight-% of the monomers with acidic functional groups or amides of acidic functional groups with respect to the total weight of the monomers. The polymeric binder furthermore contains from 2.5 to 100 mole-% dihydrazide crosslinker with respect to the keto- or aldehyde-containing monomers, optionally from 0 to 3.0 weight-% non-reactive surfactant, from 35 to 90 weight-% water, optionally from 0 to 20 weight-% other additives, and optionally from 0 to 20 weight-% humectant. Further provided herein is a process for preparing an aqueous sealing coating that includes applying a binder composition on a heat-sealable film including corona treated polyolefins.
