Standard Test Method for Determining Residual Solvents in Packaging Materials
This standard describes methods for the quantitative determination of residual solvents in flexible packaging by dynamic headspace chromatography where the chemical identities of the residual solvents to be determined are known before commencing the analysis. Residues from thermal decomposition products are not within the scope of this standard. The method is applicable to flexible packaging materials that may consist of mono- or multilayer plastic films, paper or board, foil or combinations thereof.

Standard Test Method for Determining Residual Solvents in Packaging Materials
This Standard describes a method for monitoring the levels of certain residual volatile solvents in unprinted and gravure or flexographic printed films, foils and laminates intended for packaging. The method is suitable for monitoring the presence of at least the following solvents: acetone 2-ethoxy-ethanol tetrahydrofuran isopropanol N-propanol isopropyl acetate toluene ethyl-acetate ethanol methyl ethyl ketone (butanone) N-propyl acetate isobutanol NOTE 1. Methyl ethyl ketone and tetrahydrofuran have very Similar retention times and cannot be resolved by this method. However, the presence of both solvents in any one sample rarely occurs.
