In Memory of Our Late President
Craig Bolton was more than a leader—he established a generational legacy.
As a kind, thoughtful, and humble businessman, Craig dedicated his life to growing and nurturing the company’s success while inspiring everyone around him with his humanitarian spirit and unwavering belief in giving people opportunities to thrive.
For over 30 years, he led PenPlast with vision, integrity, and compassion. With his innovative spirit, Craig was always working on designs for new moulds and products, excited and eager to showcase his pride and joy: Peninsula Plastics and Nova Environmental, and the team within it.
Today, his spirit continues to guide us. We honor his memory by upholding the principles he held dear—delivering exceptional customer service, producing quality parts, and embracing innovation while staying true to our roots.
Craig, your passion, wisdom, and dedication remain our foundation.
We hope we are making you proud.
