Clamshell design according to the specific needs of your product. We also have a large line of stock clamshells that can be inserted with a customized cavity, resulting in reduced tooling costs and lead times.


For many products a blister is the perfect solution for today's packaging needs. We will design a custom blister for your product or you may opt to choose from our large list of stock blister packaging.


The creation of a plastic tray that captures and displays your products in the most attractive manner is the goal of our Design Team. They also protect products during shipping & handling.


We combine function with design. During the critical design phase your product will be studied intensely to produce a package that is appealing, functions properly, and is easy to assemble.


Some of our customers need virgin or FDA approved material however, most of our packaging is manufactured from recycled material, such as recycled PVC.

Clamshell Packaging Corp.® is a leader in the state of Missouri for the use and promotion of recycled material. Last year alone Clamshell Packaging Corp. diverted over one million pounds of plastic from Missouri's landfills.

Clamshell Packaging Corp. is committed to using recycled PVC and we apply re-use principals when and where appropriate.
