Dear all...
We are produce seasoning and packed by flexible packaging. This film was printed by our self. during ISO 22000 assessment, the auditor arised 3 minor non conformance, one of these non conformance was : we have to check the toluene residue as the one of printing material (solvent material) in the packaging surface area which direct contact with our product.
So far we already check by using Gas Chromatography (GC) method, but we do not have any references standard regarding safety standard for toluene residue in film packaging.
FYI, the structure of our film packaging: OPP/LDPE/Al Foil/LDPE, which is LDPE was direct contact to product.
Does anybody can help us :
1. References regarding food safety limit of toluene & ethylacetate residue in the packaging surface area
2. references for the GC method to analyze toluene residue in the packaging surface area
thanks in advance,
regards
