PACKAGING LABORATORY – CHEMICAL DIVISION

The aim of the analyses performed in Chelab packaging laboratory is to determine the main characteristics to assert that a material can come into contact with foodstuffs. The regulation 1935/2004 art. 3 underlines that all materials intended to come into contact with foodstuffs shall be manufactured in compliance with good manufacturing practices so that it does not transfer its components to foodstuff in such quantities to:

The overall migration tests are determinations which verify the correspondence of the materials to one of the requisites above mentioned. They determine the total quantity of the substances that can migrate from the material to the liquids which simulate the extractive capacities of foodstuffs and establish if the material can come into contact with foodstuff.
In this way, the nature of the migrant substances (monomers, additives, technological adjuvants, catalyzers, solvents, intermediates, an so on) is not identified. For this reason, the entity of the release of the toxic substances by the material can be determined through specific migration tests.
The overall migration tests are performed by a specialized staff and according to law standards (D.M. 21/03/73 and following modifications, and Directive 2002/72/CE and following modifications), official methods (UNI EN 1186) and, sometimes, according to the Title 21 of the Food and Drug Administration (FDA).

The specific migration tests verify if the migration level of a specific substance, which has particular restrictions and is used in the production of an object, is superior to the limit imposed by the law in force.
The analytical determinations offered by Chelab laboratories include the specific migrations of monomers (e.g., phthalic acid, vinyl chloride monomer, glycols, acetaldehyde, 1-octane,1-hexene), additives (e.g. octadecyl-3-(3,5-diether-butyl-4-hydroxy phenyl)propionate, ESBO, ELO, and so on), colorants, metals (in case of inoxidizable steel, tin and chromium coated steel, glass and other metal materials), and so on. All these determinations are performed by a highly qualified staff through official technical norms, e.g. UNI EN 13130, or methods elaborated in Chelab laboratories, which are equipped with a cutting-edge instruments.

The packaging laboratory analyses paper and paperboards destined to come into contact with food.
These materials are analysed in accordance with the Italian M.D.. 21/03/73 and following modifications, to control their composition and purity requisites modifications.

The laboratory can perform the analysis both for the composition requisites and for the purity requisites.

The composition requisites (M.D..21.03.1973 attachment IV section VI) such as:

The purity requisites (M.D. 18.06.1979 and M.D. 30.05.2001) such as:

Finally, in accordance with the regulation UNI EN 646, it is possible to determine the colour solidity in coloured paper and cardboards intended to come into contact with food.
