At National Plastics, we do more than just sell clamshell packaging, we sell packaging solutions. Our design team will work with you to create a package that not only functions well, but adds to the aesthetic appeal of your product.

Working with you, we design clamshells, build the production tooling, and ship the product on time at a competitive price.

Clamshells come in a variety of shapes and sizes. The most popular is the standard clamshell box. Popular for packaging everything from fishing lures to thumb tacks, these plastic boxes are perfect for merchandising items that benefit from being seen by the customer. National Plastics has stock clamshells (link to stock-clamshells.html) or can custom design for your specific application.

Stock Clam Shells: Utilize one of our stock sizes or take advantage of our stock mold base program. Specific stock clamshells exist for golf balls and cellular phone accessories. Tri-Fold Clam Shells: A popular style because they can stand on a shelf, sit in a display, or hang on a peg wall.
Clam Shell Trays: Combine the functionality of a packaging tray with the merchandising characteristics of a clam shell. Egg Crate Clamshells: Custom designs like our golf ball 12 pack are another example of our creative packaging design.


Not all clamshells are created equally. Although we strive to provide our customers a very competitive price, we will not sacrifice quality to do so. All products are tested for clarity, wall thickness, hinge strength, and "open and closeability."
