X-ray transparency & added durability are benefits of a new conveyor belt that helps improve performance for contaminant detection in glass containers on food & pharmaceutical lines, said Mettler Toledo Safeline. The company said its new belt incorporates a slat band modular design to facilitate high-speed handling of glass containers of various sizes. The walls & bases of glass jars & bottles can vary by as much as 20%, which makes the detection of foreign bodies challenging. One issue is that previously-used polyurethane (PU) conveyor belts, while x-ray transparent, wear out quickly when handling heavy glass containers at high speeds, said the company. Heavier belts with higher weight capacities are more durable but hinder the flow of X-ray beams & reduce the sensitivity of detection. The new patented modular plastic belt combines the the benefits of both.
