GWC Packaging's Mission and Values
Ongoing Support for Your Packaging Supplies and Equipment Needs.
Packaging with Purpose. Partnership with Heart.
At GWC Packaging, we believe packaging is a critical part of your operation that deserves thoughtful strategy and reliable support. That belief has guided our evolution from a traditional family business into a modern packaging partner that understands the fast-paced world of logistics and warehousing.
Our success is rooted in the leadership of Cathy and William Shih, a husband-and-wife team whose combined strengths have reshaped GWC Packaging into what it is today.
Reinventing a Family Business
When Cathy and William took over the family business, they approached it as students, not bosses. They toured warehouses, listened to the teams, and tried to understand how things worked day to day. They asked questions about what was running smoothly and what was getting in the way. They noticed the small details that kept operations moving and the challenges that slowed them down. Those visits were not about making quick changes. They were about learning the real needs of the people doing the work. That patience and attention shaped how they made decisions and built the foundation for the company’s future.
Our Philosophy
We support warehouse teams by offering more than just packaging materials. Our goal is to share useful knowledge, provide dependable service, and be a steady resource for your day-to-day operations.
Whether it's packaging supplies, equipment, or machine repairs, we focus on solving problems early so they don’t disrupt your workflow. We don’t disappear after the sale. We stay involved, offering support during setup, troubleshooting, and anything else that comes up along the way.
Meet the Founders
William Shih, co-founder and head of sales and business development, brings years of experience and a natural talent for building strong customer relationships. His entrepreneurial mindset and strategic thinking have played a key role in GWC’s continued growth and reputation for reliability.
