Described herein is a heterophasic polymer adhesive that includes an aqueous polymer dispersion, an optional hydrophobic emulsion, and an optional surfactant. The polymeric adhesive has a water absorption of less than about 5 g/ m2 /20 minutes when dry, a seal strength of at least about 200 Newtons/meter (N/m) as measured at 25°C or 90°C, and Sufficient blocking resistance without substrate damage. |
