[PDF] Migration of conventional and new plasticizers from PVC films
The migration from the gaskets of plasticized PVC in metal closures usually far exceeds the legal limits if the packed food contains some free oil. If the gaskets continue to consist of PVC,… Expand 20 View 2 excerpts, references results and background Plasticizers in Brazilian food-packaging materials acquired on the retail market
Migration of conventional and new plasticizers from PVC films into food
The reference film was produced with DEHA and ESBO, while the other films were produced with conventional plasticizers (ATBC and Polyadipate), new plasticizers from renewable resources (Mixture of glycerin acetates – MGA and Acetic acid esters of mono- and diglycerides of fatty acids – AGM) or a plasticizer employed in toy and childcare applications (DEHT).
Plasticiser loss from plastic or rubber products through diffusion and
The migration of plasticiser from polymers to a gas phase is a two-step process that includes diffusion from the polymer bulk to the surface followed by evaporation from the surface to the...
Methods for determination of plasticizer migration from polyvinyl
In general, plasticizer migration from PVC synthetic materials can proceed via three different mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
Alternative to Phthalate Plasticizer for PVC/NBR Formulation Used
Phthalates have been extensively used in rubbers formulation as plasticizer additive for PVC and NBR promoting processing parameters or for cost reduction. The most commonly used plasticizer...
- 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 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.
- What is Mercosur technical regulation on migration from PVC cling film?
- Mercosur technical regulation on migration from plastic materials, packages and equipments intended to come in contact with foodstuffs Di (2-ethylhexyl) adipate migration from PVC cling film into packaged sea bream ( Sparus aurata) and rainbow trout ( Oncorhynchus mykiss) fillets: kinetic study and control of compliance with EU specifications
- Why do plasticizers have a specific migration compared to the overall migration?
- The fact that the specific migration of plasticizers corresponds to the values of overall migration for most films evaluated may be due to the fact that the tests of specific migration were conducted with isooctane simulant, which has greater extractive power than olive oil (simulant used in the overall migration test).
- 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.
