Oxygen-tight food container
11578200 · 2023-02-14 ·

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.

Injection stretch blow-molding (ISBM) enhancement for semi-crystalline polyolefin containers utilizing alicyclic polyolefins

An injection stretch blow-molded (ISBM) container prepared by way of injection molding a tubular preform followed by reheating and concurrently stretching and blow-molding the heated preform into the container. The container and preform comprise from 70 wt. % to 97.5 wt. % of a semi-crystalline polyolefin composition comprising one or polymers selected from polyethylene polymers and polypropylene polymers and from 2.5 wt. % to 30 wt. % of an alicyclic polyolefin composition, wherein the alicyclic polyolefin composition has a glass transition temperature, Tg, of from 80° to 145° C.

Polymers for additive manufacturing

Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away from the printed part, resulting in a part having surface cavities.
