Antiblock Additives

Minimize film-to-film contact to improve performance

Ampacet offers a wide variety of antiblock masterbatches, all designed to meet specific performance criteria such as blocking performance or optical properties. Blocking most commonly occurs when two pieces of film are pressed together such as on a take-up roll or after stacking finished converted films. Antiblock additives improve the handling and converting of film by minimizing film-to-film contact.

Traditional inorganics antiblocks are mostly based on siliceous minerals which include diatomaceous earth as well as talc. Calcium carbonate is also used to a lesser extent due to its inexpensive nature. The design of these masterbatch products is based on the understanding of the commercial availability, chemical properties, and physical properties of potential antiblocks.
