2019-9-18 · Additives, often referred to as anti-oxidants or stabilizers, are added to combat the deterioration of the plastic and to significantly extend the life span of the final product. UV stabilizers absorb UV light, protecting the plastic from its harmful effects.

Additives are substances used for a variety of reasons - such as preservation, colouring, sweetening, etc.- during the preparation of food. The European Union legislation defines them as "any substance not normally consumed as a food in itself and not normally used as a characteristic ingredient of food, whether or not it has nutritive value".
