💡 A Word from JOBPLOY
JK Materials is a plastic film factory that operates 24 hours a day using large extrusion and stretching equipment. For production roles, it is often operated on a 4-team, 3-shift basis. Since the work involves the transport of heavy rolls, slitting, and extrusion process management, wearing safety gear and following workplace safety rules are essential. Diligence to adapt to shift schedules and the ability to communicate smoothly with field managers are important. JOBPLOY provides this information for your reference.
