Printable protective layer

A coextruded multilayer film comprising a first surface layer and a second surface layer wherein:

• the first surface layer consisting of a cross-linked, non-weldable, partially neutralized copolymer of ethylene and one or more α,β-unsaturated C3 to C8 carboxylic acid and optionally, from 0.001 to 10 wt. % of a plasticizer, processing aid, flow enhancing additive, lubricant, pigment, dye, flame retardant, impact modifier, nucleating agent, antiblocking agent, thermal stabilizer, UV absorber, UB stabilizer, dispersant, surfactant, chelating agent, coupling agent, adhesive, primer, antistatic agent, crosslinking agent, or slip agent;
• and
• the second surface layer comprises an internal layer comprising a polyamide and an external layer, the external layer consisting of:
• (i) a grafted propylene or a grafted copolymer of propylene and one or more α-olefin;
• and
• (ii) optionally, from 0.001 to 10 wt. % of a plasticizer, processing aid, flow enhancing additive, lubricant, pigment, dye, flame retardant, impact modifier, nucleating agent, antiblocking agent, thermal stabilizer, UV absorber, UV stabilizer, dispersant, surfactant, chelating agent, coupling agent, adhesive, primer, antistatic agent, crosslinking agent, or slip agent.
