Chemical composition and migration levels of packaging adhesives. - FS2223

Three main areas of interest have been identified: The use of adhesives as cold seals, use of polyurethanes, and miscellaneous adhesives such as epoxy resins. A similar procedure will be used for each three. Namely:- Cold seals. Year 1 1.Months 1-2 Liaise with adhesive manufacturers and the packaging industry to catalogue the extent, nature and pattern of use of adhesives along with formulation details. 2.Month 2 Select materials giving most concern i.e. foods consumed by children, materials in prolonged and initimate contact with fatty foods, materials used at high temperatures, materials with ingredients of concern to DH. 3.Month 2-8 Obtain representative materials for test, including adhesives, their individual ingredients where possible, and converted packaging materials made thereof. 4.Months 3-9 Test the composition of the materials for potential migrants. Identify and quantify using (principally) GC, GC-MS, HPLC and HPLC-MS. 5.Month 9 Consult with FSD1 and DH. Select target substances where the nature and level give DH cause for concern. 6.Month 10-12 Conduct migration tests into food simulants. Quantify the targeted adhesive components. 7.Month 13 Discuss with industry if migrants can be eliminated or reduced by re-formulation. If no problems found move onto next material. Isocyanates. Year 2 Months 10-25 Objectives 8 - 14 Epoxy resins and miscellaneous adhesives. Year 3 Month 22-36 Objectives 15 - 21
