Antiblocking

Our minerals can help you solve antiblocking issues in polyethylene (PE) films.

Unblock your PE film production 

Blocking – when two or more layers of plastic stick together during production – can be a constant challenge when manufacturing polyethylene (PE) films.

However, there’s a simple, natural solution – flux calcined diatomaceous earth, a mineral with irregularly shaped particles that provide fewer film surface contact points and hence very low blocking force. 

Our diatomaceous earth product range Celite® will not only deliver outstanding anti-block performance, it will also boost the clarity of your film and reduce haze.

Imerys Celite® flux calcined diatomaceous earth grades provide:

  • outstanding film anti-block performance 
  • increased film clarity 
  • reduced haze

Calcined kaolin is another naturally occurring mineral with antiblocking properties. Our InFilm™ and PoleStar™ grades are highly refined, medium particle size calcined kaolins that offer a good, cost-effective balance of antiblocking, haze and clarity performance.

Finally, there’s microlamellar talc*, such as our InFilm range. InFilm improves the mechanical properties of your plastic film compared to other anti-block minerals, and provides better optical properties than conventional, lamellar talc ore.
