Migration of nonylphenol and plasticizers from polyvinyl
In this study, the migration of NP and plasticizers, such as DINA, DAA, and DALG, from PVC stretch films into food simulants, rapeseed oil, and several foods were circumstantially investigated under various conditions and their intakes were estimated. This study was conducted from 1999 to 2001. 2 Materials and Methods 2.1 Samples
Migration of Chemical Compounds from Packaging Polymers
Researchers study the migration of food-packaging compounds by exposing food or food-simulating liquids to conventional and microwave heating and storage conditions, primarily through chromatographic or spectroscopic methods; from these data, they develop kinetic and risk assessment models.
Analysis of phthalate plasticizer migration from PVDC
The MD results showed that high interaction energy and fractional free volume in PVDC/DEHP/food simulant systems accelerated the migration of DEHP. These fundamental studies would provide significant insights into the migration of environmental contaminants.
Migration from plastic packaging into meat - ScienceDirect
Migration is a known phenomenon defined as the partitioning of chemical compounds from the packaging into food, and depends on several factors. Migration assays are generally time-consuming and require specific conditions in order to investigate the behavior of the packaging in different situations.

- 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.
- 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 ).
- 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.
- Which plasticizers produce the highest migration values?
- Therefore, samples formulated with approximately 16% of DEHA (sample 1) and 18% of MGA and AGM – vegetable-origin plasticizers (samples 3 and 5) were the samples that produced the greatest values for overall migration, as can be seen in Fig. 1.
- 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 ).
