Great Lakes Packaging (GLP) is headquartered in Germantown, Wisconsin, which is located approximately 20 miles northwest of Milwaukee. Founded in 1963, the Company takes pride in doing the “unique” for the customer, while delivering service and quality unsurpassed in our industry.

In late 2014, GLP was acquired by Green Bay Packaging – which has enabled GLP to offer many more resources and capabilities to our existing and future customers.   To learn more about Green Bay Packaging, please visit the following website  www.gbp.com

GLP supplies corrugated and plastic corrugated containers, point-of-purchase products, foam and specialty packaging, fulfillment/contract packaging and related services to a broad range of customers and industries. Our goal is to work with our customers to integrate their packaging requirements and provide “one-stop shopping” where it is justified.

GLP’s business has three main product lines:

  • Industrial corrugated products and shipping containers.
