In recent years, white opaque PET bottles for dairy applications have been under increasing scrutiny for the potential effects their mineral fillers can have on the recycle stream used to create fiber. Complete with food contact approvals for the European Union and FDA, this new Lactra additive is compatible with the PET recycle stream for fibers, sheet, and strapping.   Testing also shows that in established opaque white PET recycle streams, Lactra products are suitable for closed loop bottle-to-bottle recycling.
