From Family Workshop to Established Manufacturer
Ongoing demand for custom tarpaulins drove steady growth, and in 1963 the company became SEAL SEAM (THAME) LIMITED. Jack’s son, Frank, later joined straight from school, learning his father’s craft before taking over the business. He guided it into the 21st century, combining traditional skills with modern market needs. In 1988, the company adopted the name it is known by today: Seal Seam Ltd.
