Plastic films have generally tend to stick together (BLOCK) , making it troublesome to separate film layers while using it especially LDPE, LLDPE,HMHDPE ,PP ,EVA Films.

Anti-block Masterbatches are added during manufacturing of films and bags to separate the layers easily and to prevent their sticking together. They are useful to lessen the adhesion between films and surface of other objects.

Many types of Anti-block Masterbatches are available, ranging from synthetic silica for high clarity, through natural silica to offer high performance where cost is important and clarity can be compromised, to talc where simple anti blocking without clarity is required.
