Antiblock
Antiblock masterbatch reduces the blocking force between layers of films or film-equipment surfaces.
Overview
Blocking describes the adhesion between adjacent layers of film caused by Van der Waal’s interactions between amorphous regions in the polymer. Antiblocking agents form microscopic bumps on the surface of the film to create space between adjacent layers that reduce the Coefficient of Friction and facilitates easier separation of layers.
There are many types of antiblocking agents used in polyolefin films. The common mineral-based antiblocking agents are diatomaceous earth (natural silica), synthetic silica, talc and nepheline syenite. Each type of antiblock has slightly different performance and efficiency. We offer antiblock masterbatches for polyethylene film and polypropylene film.
Features
Ingenia offers a variety of antiblock masterbatch solutions using minerals or organic antiblocking agents. Typical grades can reduce the blocking force to less than a fifth of the blocking force of neat polyethylene. Significant reductions in blocking force have been achieved using our high performance proprietary masterbatches. These antiblock solutions may be preferred for more challenging applications. Our antiblock products are often combined with slip agents to provide custom solutions, in a wide variety of film types in the agricultural films, as well as consumer goods, food and beverage packaging.
