Iam not in the paper industry, but Ive worked in the dairy, textiles and in pet foods. All major companies in the US. As far as pay, it would average around 19$per hour on the high side, 21$ depending on your knowledge of PLC's, electrical, etc. The money is on the electrical side. Major companies are looking for multi crafted people, the closer you are to an engineer and still carry a meter the better. What specifically is your questions, maybe I can help?
