Poly(m-xylylene adipamide) (nylon MXD6), D-sorbitol, and α-cyclodextrin aldehyde-scavenging agents were blended with poly(ethylene terephthalate) and thermally pressed into films. Films were stored in an acidified aqueous model solution (pH 3.6) containing a 25 μM mixture of acetaldehyde, propionaldehyde, butyraldehyde, valeraldehyde, and caproaldehyde for 1, 3, 7, and 14 d. The total amount of aldehydes sorbed by films was 2 to 10 times higher for films containing aldehyde-scavenging agents than nonblended films. Aldehyde-scavenging films demonstrated selective scalping, preferring smaller molecular weight aldehydes to larger aldehydes. Partition coefficients for smaller aldehydes were 3 to 6 times greater for aldehyde-scavenging films than control film.
