By definition, film blocking is how one describes films in contact with each other that do not move easily over one another. Blocking can also be influenced by pressure and temperature. Polyvel's antiblocks work by decreasing the contact between layers of film which prevents them from sticking. Our knowledge or multiple additive chemistries and sources allows us to customize the most cost efficient additive package for each application. Polyvel's well dispersed masterbatches are available for food contact and clear applications.
Multiple variables come into play when selecting the right antiblock. Allow Polyvel to diagnose your needs. Please contact us
