Migration of DEHP from plastic to food simulants
Badriev. In order to research and evaluate the safety of food packaging of plasticizer Di-2-ethylhexyl phthalate (DEHP) in PVC film, the migration rate of DEHP from PVC film into water food
Study of the Migration of Stabilizer and Plasticizer from Polyethylene
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
Plasticizer Migration: Ensuring Safety in Food Packaging
New plasticizer technologies allow formulators to achieve performance requirements while meeting best practices for food safety and migration By William Arendt, Marianne M. Conner, Emily McBride Food safety concern has extended to migration of materials from packaging, such as additives from ink, coatings and adhesives into the food. Figure 1.

The migration of plasticizer increased with storage time of the wrapped product; for dibutyl phthalate, for example, levels increased from 0.2 to 6.7 mg/kg over the period from 0 to 180 days storage of a chocolate-coated confectionery product.
Migration from plasticized films into foods. 3. Migration of phthalate
A UK survey of plasticizer levels in retail foods (73 samples) wrapped in plasticized films or materials with plasticized coatings has been carried out. A wide range of different food-types packaged in vinylidene chloride copolymers (PVDC), nitrocellulose-coated regenerated cellulose film (RCF) and cellulose acetate were purchased from retail and 'take-away' outlets.
- How do plasticizers migrate into food?
- The migration of plasticizers into food depends on various factors: diffusion constant of the migrating substance, the solubility in the given food, prevailing temperature, contact time, concentration gradient and the surface-to-volume ratio.
- 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.
- 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.
- 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 increase migration?
- The increase of migration due to the plasticization effect of additives (especially plasticizers) can easily be comparable – both in extent and mechanism – with the promoting effect of increased contact temperature.
