ARTiSEAL速 Water-base PVC-free Sealant Compound for Twist Caps
PVC-free compound for Twist caps ARTiSEAL® Background Legislation requirement European Commission Directive 2007/19/EC, effective since April 2009 A new overall migration limit (OML) of 60 ppm becomes applicable to metal closures (300 ppm before!) PVC lined caps fails under this directive, particularly due to plasticizers migration when used with sterilized fatty foods Alternative sealants with minimized migration potential to replace PVC in metal caps are needed
Market requirement Explicit purpose of principal fillers of going to PVC-free packaging Unilever, Wallmark and other intent to replace PVC from packaging as soon as possible. In the next years they want to use pvc-free alternatives in the metal closures. June 2012 Page 2 ARTiSEAL® ACTEGA Artística
