A conveyor belt has a traction layer () in the form of a woven textile that is provided with a polymer surface coating. The surface coating is formed of a base layer () and a functional surface layer (). The functional surface layer () has an antimicrobial additive and is substantially thinner than the base layer (). The division of the surface coating into a base layer () and a functional surface layer () allows a effectiveness against microorganisms in the area of the conveying zone. This can be achieved by using either a lower amount of antimicrobial additive in the functional surface layer (), being a less expensive process, and achieving just as high a concentration of antimicrobial additive. This can also be achieved by using the same amount of additive resulting in a substantially higher concentration and thus a higher effectiveness against microorganisms.

Conveyor belt with a polymer surface coating containing an antimicrobial additive

A module for a modular conveyor belt, is described. The module is of a micocellular polymeric foam produced by an injection molding process. The foam polymeric material exhibits excellent mechanical properties required for modular conveyor belts capable of withstanding long service lives. Also, the reduced weight in comparison to conventionally molded modules helps decrease wear on the conveyor belt support structures including the drive sprockets.

Module for a modular conveyor belt having a microcellular structure

A module for a modular conveyor belt, is described. The module is of a sandwich layer construction having a core polymeric material completely surrounded by a skin polymeric material. The skin material includes an antimicrobial material for inhibiting bacterial growth on the module, and the conveyor belt is particularly useful for conveying and transporting foods including food processing and food handling applications.
