additivemeans a substance which is intentionally added to the plastic to achieve a physical or chemical effect during processing of the plastic or in the final material or article and it is intended to be present in the final material or article, including substances in a solid state the surface of which becomes bonded to the polymers that constitute the plastic;
aid to polymerisationmeans a substance which initiates polymerisation and/or controls the formation of the macromolecular structure;
food simulantmeans a test medium imitating food;
functional barriermeans a barrier consisting of one or more layers of any type of material which ensures that the final material or article complies with Article 3 of Regulation (EC) No 1935/2004 and with the provisions of this Regulation;
hot-fillmeans the filling of any article with a food with a temperature not exceeding 100 °C at the moment of filling, after which the food cools down to 50 °C or below within 60 minutes, or to 30 °C or below within 150 minutes.
multi-material multi-layermeans a material or article composed of two or more layers of different types of materials, at least one of them a plastic layer;
non-fatty foodmeans a food for which in migration testing only food simulants other than food simulants D1 or D2 are laid down in Table 2 of Annex III to this Regulation;
non-intentionally added substancemeans an impurity in the substances used or a reaction intermediate formed during the production process or a decomposition or reaction product;
overall migration limit(OML) means the maximum permitted amount of non-volatile substances released from a material or article into food simulants;
plasticmeans polymer to which additives or other substances may have been added, which is capable of functioning as a main structural component of final materials and articles;
plastic multi-layermeans a material or article composed of two or more layers of plastic;
polymermeans any macromolecular substance obtained by:
polymer production aidmeans any substance used to provide a suitable medium for polymer or plastic manufacturing;
reprocessing of plasticmeans the remelting, mixing, reacting or otherwise processing of plastic materials that result as a by-product from an intermediate or final manufacturing operation in the manufacture of plastic materials and articles, alone or combined with material originating from other manufacturing operations, by applying, if necessary, transfer and operations to make the use of these by-products possible again;
restrictionmeans limitation of use of a substance or migration limit or limit of content of the substance in the material or article;
specific migration limit(SML) means the maximum permitted amount of a given substance released from a material or article into food or food simulants;
specificationmeans composition of a substance, purity criteria for a substance, physico-chemical characteristics of a substance, details concerning the manufacturing process of a substance or further information concerning the expression of migration limits;
