OXYGEN-TIGHT FOOD CONTAINER
20230075620 · 2023-03-09 ·

The invention relates to a food packaging unit (20) comprising a food container (1) for receiving a liquid, pasty or free-flowing food. The injection-moulded, single-component, cup-shaped base body (2) of the food container surrounds, with a wall (5), a bottom (6) and an outwardly projecting collar (7), an opening (4) which is closed by a food-container-covering film (10) applied to the collar (7). The food container (1) is injection-moulded in a single layer from a polymer blend comprising two components, a first component of which being PVOH or a PVOH copolymer. The food-container-covering film (10), which can be applied to the plastic food container (1) in order to close the opening (4) by sealing, welding or adhesion, comprises a cellulose-containing layer which is coated with PVOH, or a PVOH polymer blend layer.
