| description | The present invention provides water-based coatings that provide liquid resistance when applied to various substrates. In some embodiments, more than one layer of coatings can be applied, using multiple coating stations. The coatings are particularly suitable for cellulosic substrates such as paper or paper board. In addition to liquid resistance, the coatings have good heat sealability, and are resistant to roll blocking. Preferably, the coatings are recyclable and/or repulpable with the substrates to which they are applied. The coating compositions comprise one or more polymer binders, and one or more particles. Preferably, at least one polymer binder has a glass transition temperature (Tg) less than 10° C. Preferably, at least one polymer binder has a heat seal onset temperature of less than 200° C. Preferably, at least one particle has a mean particle size greater than 4 μm. It is also preferable that the particles have a melting point greater than 60° C. |
