SoPure® is an original solution because it is a capsule free of plasticizers such as phthalates—used to make PVC flexible—and made with Provalin®, a compound produced by Actega.
Migrational properties of Provalin® for SoPure®
Provalin® is a blend of thermoplastic elastomers (TPE) composed by more than 95% polymer and less than 5% lubricants and stabilizers.
On the other hand, the PVC compound has a percentage of liquid plasticizers not linked to polyvinyl chloride; therefore, it is potentially able to migrate into food, which varies between 35 and 40%.
