The present disclosure provides a home compostable extrusion coated substrate which includes a paperboard substrate having at least a first side and a layer of an extrusion coating applied over at least a portion of the first side. This extrusion coating is made up of from about 30 to about 99.5 weight percent of at least one poly(hydroxyalkanoate), and from about 5 weight percent to about 69.5 weight percent of at least one compostable polymer which is selected from the group consisting of poly(lactic acid), poly(caprolactone), polyethylene sebicate), poly(butylene succinate), poly(butylene succinate-co-adipate), poly(butylene adipate terephthalate) and mixtures thereof. Preferably, in accordance with the present disclosure, it is also preferred that the extrusion coated substrate is home compostable, as determined by ASTM D6868. |
