packaging laboratory - chemical division

The chemical division of packaging laboratory performs tests in order to verify the main characteristics necessary to establish whether a material is suitable to come into contact with foodstuffs. The regulation 1935/2004 art. 3 establishes that all the materials in contact with the foodstuffs, besides being produced in compliance with good manufacturing practices, shall not transfer to the foodstuffs components in such quantities to:

Overall migration tests are determinations which verify the correspondence of the materials to the above mentioned regulations. The migrations determine the total quantity of the substances that can migrate from the material to the liquids which silmulates the extractive capacities of the foodstuffs; they allow to evaluate the inactivity of the material towards the foodstuffs. In this way, the nature of the migrating substances (momomers, additives, technological coadjuvants, catalyzers, solvents, intermediates, and so on) are not identified: the entity of the migration of the toxic substances from the material can be determined through specific migration tests.
The tests of overall migration, performed by qualified staff, can be performed according to law methods (MD 21/03/73 and following modifications and Directive 2002/72/EC and following modifications) official methods (UNI EN 1186) and, in some cases, according to the Title 21 of  Food and Drug Administration (FDA).
The tests of specific migration aim to verify if a specific substance, considered as restrictive, has been used in the production of an object; in addition, it establishes if the substance migrates in a quantity that exceeds the limits permitted by the legislation in force. The analytical determinations of the laboratory include the specific migration of monomers( for example phthalic acid, vinyl chloride monomer, glycols, acetaldehyde,1-octene, 1-hxene and so on), additives (for example: octadecyl-3-(3,5-diether-butyl-4-hydroxy phenyl) propionate, ESBO, ELO, and so on) dyes, metals (in case of stainless tinplate and chrome plate, glass,  and other metallic materials) and so on. All these  determinations are performed by a qualified staff through technical official regulation, for example UNI EN 13130 or by internal methods developed by our laboratories that are provided with cutting-edge equipments.
In addition, in the packaging laboratory are performed controls of paper and paperboard destined to alimentary contact. For these materials, regulated at a  national level by MD 21/03/73 and following modifications, are performed tests to verify the requirements of composition and purity provided by the regulation in force.
The laboratory is able to perform the determination both for composition requirements and for purity requirements.
