Workforce Protective Leagues

The craft of glassmaking has been a part of America’s manufacturing heritage since Colonial Jamestown was established in 1608. Today, there are 15,000 skilled workers 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 web site.
