Study of the Migration of Stabilizer and Plasticizer
This study investigates the determination and migration of stabilizers and plasticizers from polyethylene terephthalate (PET). Two methods [ultrasonic extraction with dichloromethane or methanol and total dissolution with phenol/tetrachloroethane (m:m/1:1)] for pre-concentration of additives in PET
Analysis of phthalate plasticizer migration from PVDC
Based on the experimental data of gas chromatography-mass spectrometry, an improved artificial neural network was first established to predict the migration of 2-ethylhexyl phthalate (DEHP) plasticizer from poly(vinylidene chloride) (PVDC) into food simulants (ie., heptane, ethanol and water).
Migration of Plasticizers into Food - Eurofins Scientific
Plasticizers generally are soluble in fat, and the migration from packaging into fatty foods such as oils, pesto or season-ing sauces is therefore of major im-portance. Plasticizers also occur in dry foods pack-aged in cardboard, if the latter is glued by dispersion adhesives containing plasti-cizers or if plasticizers get into packa-

Migration of plasticizers into food - Canadian Packaging
The dominant applications—about 90 per cent—are for plastics, especially polyvinyl chloride (PVC), though it can also be used to improve concrete, clays, and related products. Products containing a high proportion of oil are particularly affected by transfer of plasticizer into the food, since plasticizers are soluble in oil.
- Do plasticizers migrate into acidic foodstuffs?
- Thus, it has been demonstrated that a contact for prolonged time up to 40 °C did not promote the migration of plasticizers into acidic foodstuffs, but the migration of plasticizers to fatty foods can be high (75%–90% loss of plasticizers) and limit the use of PVC films as fatty food packaging. 1. Introduction
- Do plasticizers migrate into food simulants?
- In addition, commercial films have been evaluated as to plasticizers concentration and specific migration into food simulants. It was found that 25% of the samples comply with the specific migration limits for fatty foods contact while 50% might be used for contact with fatty foods with FRF 2–5.
- How much plasticizer migrates to the packed food?
- The quantity of plasticizer that migrates to the packed food depends on several factors such as the fat contents of the food, type and initial concentration of the plasticizer in the packaging material, storage time and temperature and the contact area ( Goulas, Salpea, & Kontominas, 2008 ).
- Does PVC film affect specific migration of plasticizers into aqueous acidic foods simulant?
- The samples of commercial PVC film displayed lower values of specific migration of plasticizers into aqueous acidic foods simulant than the quantification limit (LOQ) of the respective methods, even with concentration of approx. 40% in the formulation of the film ( Table 9 ).
- Does plasticizer affect the migration of additives?
- The results confirm that the presence of plasticizer in the plastics enhances swelling, and thus the migration of additives. The plasticizer content is in strong correlation with migration rate for all additives, except for PLA-Irgafos 168 samples.
- Do plasticizers migrate better than SML?
- Migration performance of conventional and new plasticizers were investigated. Distinct migration was due to different interactions between the plasticizers. Correlation between migration and tensile properties of the films was done. Most of commercial samples showed migration lower than SML established.
