Screening of volatile organic compounds (VOC) from paper, board, and plastics. The method can be used to analyze volatile residues from printed packaging as well as to measure the decontamination efficacy of the recycling process (e.g., rPET, recycled fibers). The following substances are included in the test package: Substance CAS No LOQ (mg/m2) 1-methoxy-2-propanol 107-98-2 0.1 1-propanol 71-23-8 0.1 1,3-dioxolan 646-06-0 0.1 2-butanol (sec-butanol) 78-92-2 0.1 2-butanone, methyl ethyl ketone (MEK) 78-93-3 0.1 2-Ethoxyethanol 110-80-5 0.1 2-methyl-1,3-dioxolane 497-26-7 0.004 2-propanol, Isopropanol (IPA) 67-63-0 0.1 Acetone 67-64-1 0.1 Acetylacetone 123-54-6 0.1 Alpha-methylstyrene 98-83-9 0.1 Benzene 71-43-2 0.004 Cyclohexane 110-82-7 0.1 Cyclohexanone 108-94-1 0.1 D-limonene 138-86-3 0.004 Dichloromethane 75-09-2 0.1 Ethanol 64-17-5 0.1 Ethoxypropanol 1569-2-4 0.1 Furan 110-00-9 0.1 Methyl isobutyl ketone (MIBK) 0108-10-1 0.1 n-Octane 111-65-9 0.1 Ethylbenzene 100-41-4 0.1 Hexane 110-54-3 0.1 Heptane 142-82-5 0.1 Sum of o-xylene, m-xylene, and p-xylene 95-47-6; 18-38-3; 16-42-3 0.3 2-butoxyethyl acetate 0112-07-02 0.1 Ethoxypropyl acetate 54839-24-6 0.1 1-methoxy-2-propyl acetate 108-65-6 0.1 Propyl acetate 109-60-4 0.1 Isopropyl acetate 108-21-4 0.1 2-ethoxyethyl acetate 111-15-9 0.1 Isobutyl acetate 110-19-0 0.1 Methyl acetate 79-20-9 0.1 Ethyl acetate 141-78-6 0.1 n-Butanol 71-36-3 0.1 Butyl acetate 123-86-4 0.1 Methanol 67-56-1 0.1 Toluene 108-88-3 0.1 2-methoxypropyl acetate 7657-7-4 0.1 Tetrahydrofuran 109-99-9 0.1 Styrene 100-42-5 0.1

Determination of formaldehyde (CAS 50-00-0) content in cold or hot water extracts of paper or board. The method is suitable, for example, for an analysis of formaldehyde migration by the German BfR Recommendation XXXVI. The migration limit for formaldehyde is 1.0 mg/dm² of paper or board. Formaldehyde is used in various chemicals and additives that are used in paper and board production.

Specific migration of dialkyl ketones (DAKs) that originate from alkyl ketene dimer (AKD) hydrophobic sizing agent of paper and board. According to BfR XXXVI recommendation, the limitation for the migration of AKD DAKs is 5 mg/kg of food or food simulant.

Glyoxal (CAS 107-22-2) can be used as a cross-linker in paper, board, corrugated board, and textile products. According to German BfR Recommendation XXXVI on paper and board food contact materials, the extract of the finished product must not contain more than 1.5 mg of glyoxal per dm2.
