Whilst completing his Bachelor’s degree, Piyapong’s family started the labeling business Trisan. During that time, he had the chance to learn about the company. Trisan started printing using letterpress 17 years ago, moving into offset and flexo, now also printing cartons. Today the company is committed to developing environmentally friendly products through productive printing and converting technologies and proceeding every process with full responsibility, including resource usage. After graduating, Piyapong fully focused on learning about the business and entire printing process; starting with paper work, later working as a press operator, controlling quality systems and dealing with customers in the sales department. Along the way, he has had opportunities to exchange working experiences and opinions with customers and suppliers, both domestic, and international. Piyapong has gained diverse working perspectives which he later adopted, as well as keeping up to date with the latest technologies. His potential has grown along with the company's, and he was appointed Managing Director last year.
