Slip & Antiblock Products Platform
An Antiblock masterbatch is usually added into a polymer film recipe to provide two main effects. The ease of rolling the polymer film on itself. During the process, air bubbles can be trapped in between film layers – causing defaults & non-flat film aspect during unwrapping. To avoid the blocking effect – caused by the adhesion between two layers.
Objective is to generate heterogeneous surface, brought by mineral or organic fillers. Polytechs SW Antiblock & Slip product range does provide industry standard references – and can provide tailor-made masterbatch upon request.
