Zusammenfassung:	A barrier layer (20) for packaging, and a sheet-like composite layer (90) for packaging, and a packaging container (9) thereof. The barrier layer (20) for packaging does not comprise a metal layer, and the barrier layer (20) for packaging comprises a base layer (200) and a first barrier layer (201) stacked on the base layer (200); the base layer (200) mainly comprises a base layer mixture, and the base layer mixture comprises at least two base layer polymers; the first barrier layer (201) comprises a metal oxide; the at least two base layer polymers comprise a first base layer polymer and a second base layer polymer, and the first base layer polymer is different from the second base layer polymer, so that the barrier layer (20) for packaging has at least two melting point peaks. La présente invention concerne une couche barrière (20) pour emballage, et une couche composite de type feuille (90) pour emballage, et un récipient d'emballage (9) associé. La couche barrière (20) pour emballage ne comprend pas de co
