We were recently approached by a client in the plastic bag manufacturing industry for a solution to a quality control issue. The company was experiencing inconsistencies and throughput problems on one of their bag lines due to a belt issue. The source of these problems originated from the inexpensive welded and unsupported green belt used to thread the process plastic film onto the bag making machine. The client thought switching to a non-stretch belt would be a solution.
Working closely with the client on product improvement and development, we engineered a knitted endless belting solution made from polyester woven fabric with a durable urethane coating. The belts were manufactured as matched sets with dimensions of 28″ and 34″ in length, ½” in width, at 1 mm thick, all to tolerances of +0/-0.0005″. The client realized an immediate improvement in quality once the new stable urethane belts were installed on the machinery.
Our company provided a seamless belting solution that greatly improved the manufacturing process for this plastic bag manufacturer. Please contact Megadyne Belt Corporation of America for additional details on this belting project.
- Company was using an inexpensive welded unsupported belt for process plastic film on a bag making machine.
- Client needed to improve throughput and consistency in the quality of the bags. They wanted to convert to a non-stretch belt.
- The Megadyne Belt Corporation of America’s solution was a polyester fabric supported belt with a urethane coating in matched sets for length.
- In picture, green belt was the original belt, ours is the clear stable urethane material.
