GPI & Workforce Protective Leagues
The craft of glass making has been a part of America’s manufacturing heritage since Colonial Jamestown was established in 1608. Today, more than 15,000 skilled workers are employed by glass container manufacturing companies across 41 plants in 20 states.
The Glass Packaging Institute values the contribution of this workforce and what it means to local, state, and national economies. Their ideas, energy, and commitment are key to a quality packaging product, one made from all-natural, readily available domestic raw materials.
We are proud to work on behalf of the men and women of the glass container manufacturing industry and the member companies that employ them. We will be sharing information and ideas with League members at regional and national gatherings throughout the country, as well as on this section of the website.
