MERRILLVILLE, Ind. (AP):  A northwestern Indiana company that makes single-load detergent packets for dishwashers and clothes washers is planning to add about 100 workers in the coming 18 months.

Merrillville-based MonoSol is in the midst of a $39 million expansion at its LaPorte plant. MonoSol president Scott Bening says the company also is looking for another northwestern Indiana site to build another production facility next year.

MonoSol is owned by Japanese company and is the largest producer of the water-soluble capsules such as Tide Pods.

MonoSol executive John Gornto says it expects about 70 percent of the new employees to be for manufacturing positions, with others in engineering and administrative jobs.
