Founder's Story

Hong Kong Paper Products: 40 Years of Eternal Quality, Inheriting the Immortal Spirit

Sum Hing Carton Box Factory is one of the few local paper mills in Hong Kong. Its founder, Mr. Wu, prides himself on producing high quality carton boxes that not only embrace Hong Kong’s historical sentiment, but also bring superior quality to each and every one of our customers. With the spirit of “Think Outside the Box”, the company has gone through 40 years of ups and downs, witnessing the ups and downs of Hong Kong from its inception in the 70s to today.

Times are changing and we are growing in the midst of change. Originally, Sum Hing Carton Box Factory was not a carton box manufacturing company, but a transformation of Sum Hing Wooden Box Factory. In the 1960s, Hong Kong’s economy was growing rapidly and the manufacturing industry was booming. Mr. Wu’s father founded the Sum Hing Wooden Box Factory, specializing in the production of wooden boxes, which were mainly used to contain red wine. However, in the 70’s, the industrial environment of Hong Kong changed, and Mr. Wu and his father realized the changing market demand, so they decisively transformed the wooden box factory into a paper products factory. Mr. Wu and his father realized the change in market demand and transformed the wooden crate factory into a paper products factory. With the excellent quality, the factory successfully won the trust of customers.
However, the good times did not last forever. Starting from the 1980s, Hong Kong’s manufacturing industry gradually declined, and many local factories were relocated to the Mainland. The prosperity of that time no longer existed, and Hong Kong’s manufacturing industry was faced with enormous challenges. However, Mr. Wu always believed that “Hong Kong is our root” and refused to give up. He and his team worked hand in hand to face the difficulties, and they did not back down in order to protect the local quality. Most of the employees have been partners for 20 years, and they have weathered the storm together as brothers. Together, they uphold the superior quality and service of the paper mill and maintain a friendly relationship with customers.
Being a Hong Kong manufacturer has its own cultural mission. We are constantly striving to provide the best quality products to our customers, both in terms of service and products. With the credo of “Treating people with honesty and sincerity”, Sum Hing Carton Box Factory has built up sincere trust and deep emotions.
In this journey, Sum Hing Carton Box Factory has grown and shared success with its business partners. We not only maintain a good working relationship, but also work together to grow and share success. The close ties with our employees, customers and partners have formed a big family and become the most important pillar. In order to provide a superior quality of service, Sum Hing will adjust its services and products according to the needs of customers, creating unparalleled value.
Sum Hing Carton Box Factory has experienced ups and downs in the course of nearly half a century, but Mr. Hu’s pursuit of quality has never ceased. In the wave of industrial transformation, Mr. Hu continues to break through, innovate and never give up. “Think Outside the Box” is not only Mr. Hu’s motto, but has also become the company’s core value. Mr. Hu believes that no matter in business or in life, we must go beyond ourselves and break through the boundaries. Even if we make cardboard boxes, we can create unlimited possibilities.
From the industrial era in the 60’s to today’s technologically networked era, Sum Hing Carton Box Factory is ready for the new era and transformation. We look forward to providing quality carton products and services through more diversified channels to meet the needs of different customers.

With the development of industry and technology, environmental protection has become increasingly important. For Sum Hing Carton Box Factory, sustainability is not just an option, but a responsibility. Sum Hing is committed to improving the recycling process, minimizing waste and using environmentally friendly materials. Environmental protection is incorporated into the daily operation of each production process, fulfilling the responsibility of a social enterprise.

Facing the pressure of global competition, as a local brand in Hong Kong, Sum Hing Carton Box Factory will not stop at the status quo. We will understand the needs of the local market and explore more diversified and user-friendly products and services, focusing on satisfying the needs of local consumers.
Looking ahead, we will continue to pursue excellence and keep abreast of the times with our “Think Outside the Box” philosophy. We are committed to strengthening and expanding the local market. As our founder, Mr. Hu, said, “We can achieve excellence even in the manufacture of cardboard boxes, as long as we have the dream and determination. This is exactly what we are committed to and where we are headed in the future.”

In this journey of discovery, despite the long road ahead, we will continue to uphold quality and move forward together. We will turn challenges into opportunities and carry on the spirit of immortality.
