Curex masterbatches are typically added to the plastic resin during the film blowing process.

For convenience Curex is added by the usual automatic mixers used for other additives like slip and anti-block masterbatches. Gravimetric mixers preferred.

Curex will migrate to the two film surfaces like other slip-additives and has no negative effect on slip-levels.


Curex masterbatches are not meant to be added to the adhesive, but to the lamination films. This is the basic idea of the invention.
