Abstract
The present invention provides a container made from an aliphatic polyamide, said polyamide containing at least 0.2 wt. % of an additive selected from ortho-phosphorous acid, hypophosphorous acid, alkali metal salts and alkaline earth metal salts thereof. The containers are particularly useful for packaging foods, e.g. frozen dinners. The additive in the container minimizes browning of the container from exposure to high temperatures experienced in conventional ovens.
