MATERIALS IN CONTACT WITH FOODSTUFFS

Paper and paperboard destined to contact with food

Papers and paperboards - alone or coupled each other or with other materials - might be used in direct contact with foodstuffs, provided that they satisfy both the general requirements of EC regulation 1935/2004 and the national regulation  D.P.R. 777 of 23.08.1982 and following modifications, and the requirements reported in the MD 21/03/73 and following modifications.

• Make the food toxic
• Imply a deterioration of their organoleptic characteristics

For completeness of information we report the limits fixed by the legislation in force:

• Raw fibrous materials: must represent at least 75% w/w of  papers and paperboards destined to contact with foodstuff for which migration tests are provided (for example: pizza) and at least 60% w/w of papers and paperboards destined to contact with foodstuff for which migration tests are not provided (for example: rice, salt, pasta)
• Charge substances:: must represent maximum 10% w/w of papers and paperboards destined to contact with foodstuff for which migration tests are provided (for example: pizza) and maximum 25% w/w of papers and paperboards destined to contact with foodstuff for which migration tests are not provided(for example: rice, salt, pasta)
• Not fibrous raw materials: all fibrous materials to be transformed in paper must be worked and opportunely mixed with auxiliary substances which – according to the legislation in force - must be present in quantities not exceeding 15% w/w in papers and paperboards destinted to contact with foodstuffs.

The Ministerial Decree 21/03/73 and following modifications provides also the verification of some requirements of purity, in particular:

The materials destined to contact with foodstuff  - besides avoiding the transfer of   substances that can make toxic the foodstuff  - must not imply a deterioration of organoleptic characteristics. In order to evaluate in advance the possibility that a contact  with the material of the packaging leads to a olfactory and/or taste defect of the tests we perform tests to verify the organoleptic qualification of the material of packaging. Olfactory and gustatory tests are made on foodstuff or on their simulants in contact with the packagings investigated. Sensory tests conducted at Chelab laboratory refer to rules internationally recognized (for example UNI EN 1230); but on the basic of specific necessity of the Costumer can be agreed the best suitable operative procedures to needs/products of the Costumer always in the respect of the basic requirements of the rules of sensory analysis.
Since the origin of an organoleptic defect can derive from:

Chelab laboratory - gifted with most advanced equipments - perform activity of research aimed to the identification and quantification of volatile substances that might migrate from the packaging to the foodstuff and to the headspace inside the packaging.
