Beschreibung
Zusammenfassung:	A multilayer structure may include a polyethylene-based polymeric film comprising: a sealing layer; at least one middle layer; and a printing layer; and an external layer of ultraviolet or electron beam curable ink or varnish cured on the printing layer of the polyethylene-based polymeric substrate, wherein the multilayer structure has a thermal surface resistance such that when sealing bars are applied to the polyethylene-based polymeric film in cycles of sealing of no more than 2 seconds and at a temperature corresponding to the melting temperature of the polyethylene-based polymeric film, the sealing bars remain free of polymer.
