• a coextruded polymeric backing comprising:
• a first layer comprising an amorphous polyamide comprising an epoxide chain-extended polyamide, the first layer having first and second opposing major surfaces;
• and
• a second layer comprising a polar-modified polyolefin comprising a grafted polyolefin comprising (i) a polyolefin and (ii) one or more grafted polar groups in an amount of 0.1-8 wt-%, based on the total weight of the grafted polyolefin, the second layer having first and second opposing major surfaces;
• wherein the first major surface of the second layer is in contact with the second major surface of the first layer;
• and
• an acrylic pressure sensitive adhesive layer in contact with the first major surface of the first layer of the backing.
