Food Belts

Thermoplastic polyurethane is widely used in food processing as a belt coating material. Habasit’s coating technology ensures a superbly smooth surface, no porosity of the coating layers, and a homogeneous belt thickness.

TPU belts provide high flexibility even at low temperatures, combined with excellent abrasion- and wear resistance. TPU’s resistance to edible fats and oils makes it a widely used choice for multiple applications. The closed belt surface does not develop micro-cracks and thus reduces the risk of microbes settling in.

Thermoplastic olefin coatings are used when the belt surface needs to deliver excellent chemical resistance and outstanding product release. Especially the Habasit Cleanline belt range has been designed to meet the most stringent demands of the food industry. Featuring a specially modified thermoplastic olefin coating, these belts offer numerous added-value benefits. Polypropylene coating is used when elevated temperature needs to be paired with good release properties.

As food contact materials, fabrics offer very good release properties. This is provided either inherently through the suction effect of cotton, wool, polyamide, or other fibers, or by impregnation, since skim-coated fabrics offer one of the lowest coefficients of friction for accumulation and pushing off of goods.

PVC coated belts are a good choice for handling both wet and dry foods, such as dough or processed meats and poultry. PVC coating is also used on heavy belt carcasses. Nonwoven belts are especially suitable for the heavier loads, while belts with interwoven design offer good oil resistance through their PVC coating.

Silicone is  a common food contact material used in food handling. Belts coated with silicone provide excellent release properties, high temperature resistance, and good hydrolysis- and chemical resistance.
