Migration test. Small squared strips of polystyrene ( 3 mm ×3 mm) with approximately 1 mm of thickness were placed between two PVC sheets of 2 mm of thickness, and kept under mild pressure (217 kPa) in a oven at 50 °C for 1 week. Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer

Migration of dioctyladipate plasticizer from food-grade PVC

Food-grade PVC film containing 28.3% dioctyladipate (DOA) plasticizer was used to wrap chicken meat samples, with and without skin, contained in a polystyrene tray. Samples were then irradiated with γ-radiation [60Co] at doses equal to 4 kGy and 9 kGy corresponding to “cold pasteurization”. Irradiation was carried out at 8–10 °C and samples were subsequently stored at 4–5 °C

The study of the extraction and migration of PVC plasticizers is of great importance for different reasons. Extraction of the plasticizer can occur in PVC films in contact with food, in bags or pipes in contact with biological fluids, such as blood, or even when a child could chew a PVC toy.

Migration of Chemical Compounds from Packaging Polymers

Slip additive migration was highest from 65 μm LDPE film, compared to PVC or PS films (<1% of the total compounds). The difference in migration levels can be attributed to the low solubility of fatty acid amides in LDPE and the high penetration rates into LDPE polymer, which increases diffusion rates (Cooper and Tice 1995 ).

Phthalates (PAEs) are used as plasticizer for producing food contact materials. However, PAEs can contaminate foodstuff through chemical migration and present serious environmental concerns. This study aims to investigate the migration of five common PAEs (diethyl phthalate, diisobutyl phthalate, dibutyl phthalate, butyl benzyl phthalate, and di(2-ethylhexyl)phthalate) from polyvinyl chloride

Thermoplastic polyvinyl chloride (PVC) is a rigid polymer that is softened by the addition of plasticizers in the manufacture flexible films, such as cling films. The most commonly used plasticizers are ortho -phthalates, which are esters of 1,2-benzene dicarboxylic acid (phthalic acid), and the para and meta isomers thereof.
