SolutionsClamshell Packaging

Over the past 50 years, Indepak built its reputation as the leading manufacturer of custom clamshell packaging in the Northwest by specializing in the production of high-volume, precision clamshell packaging. 

Design Innovation

Over the years, we have built a reputation for being more than a thermoformer. We work with our clients to create aesthetically pleasing and functional designs that not only showcase one’s product, but protect it from damage and theft. Our ability to solve virtually any thermoforming challenge has allowed packaging designers to explore options beyond basic clamshells.

Precision Custom Clamshells

When specifying a clamshell package, we consider a variety of factors including weight, strength, presentation, and cost containment. After evaluating these criteria, we select the best plastic materials for your application. Then, we determine which machine is best for your application, volume, and other needs - knowing that we have multiple lines of high-speed thermoforming equipment from which to choose.

Our ability to manufacture highly precise clamshell trays has proven invaluable to companies that need to protect and limit the movement of parts within the package.
