The feasibility of use of new products in food contact adhesive/coating applications is discussed. Plasticizers used in food packaging must have the 21 CFR 175.105 coverage. It is important that the raw material supplier knows exactly what coverage is desired. Based on the extraction results, a calculation of the estimated daily intake (EDI) of an average adult can be performed. The plasticizer of choice is propylene glycol dibenzoate (PG). The other plasticizers in the blend are dipropylene glycol dibenzoate (DP) and diethylene glycol dibenzoate (DE). Commercial grade polyvinyl acetate homopolymer (PVA) and ethylene vinyl acetate copolymer (VAE) were selected. A blank adhesive emulsion was also included to stainless steel foil at a specified film thickness, dried and then exposed to food stimulant extraction. The results are promising and indicate that PGDB has a reasonable opportunity to attain 21 CFR 176.170 and 180 coverage. Source

Dibenzoates are low VOC/non-SVHC plasticizers that exhibit excellent performance. While the use of cheaper plasticizer alternates may be viable for some applications to reduce the cost of overall formulation careful evaluation of physical properties must be conducted in order to determine whether the loss in performance is acceptable. Even an addition of triacetin to a dibenzoate blend can cause a noticeable drop in performance of both homopolymer and copolymer systems. Triacetin and 2,2,4-trimethyl 1-3 pentane diol diisobutyrate (TMPDDIB) also demonstrate high volatility which may become a problem as regulatory bodies take more interest in the VOC s of formulations and articles.
