According to Industrial Packaging:

Deep-fried, boiled, or on the half shell. No matter how you eat them, one thing remains the same. Plastic clamshell containers taste absolutely awful! But, they make really great food packaging supplies.

All references to our salty seafaring friends aside, the packaging containers known as clamshells do, in fact, resemble their ocean-dwelling namesakes.

In the wide world of packaging, clamshells are a type of plastic container commonly used in food packaging applications. They can be found in supermarkets, gas station food-marts, grab-and-go food bars, and various other food retailing institutions.

Clamshells are a type of carded packaging. Carded packaging is a collection of packaging materials that generally feature two components. These components included backers made from plastic, skin-board, or paperboard and front-facing materials made of various plastic formulations.

Clamshells come from the same family of packaging materials like blister packs and skin packs. These easy-to-seal containers are ubiquitous. Chances are, you have seen them out in the wild.

Industrial Packaging has helped various types of food packaging companies implement these containers. In this article, we will take a deep-dive into the ocean of carded packaging. And we will explore the natural habitat of these flexible plastic containers.

With the information in this article, you will be able to decide if clamshell packaging makes sense for your product packaging needs or not.

Clamshell Packaging

Clamshells are a type of carded packaging. They are most commonly made of plastic. But, they can also be made from styrofoam, paperboard, cardboard, and recycled paper. They are made from two identical “shells.” The shells are attached on one side and have tabs on the other side. The tabs allow them to be closed and locked shut. They resemble actual clamshells and open and close similarly.

What Packaging Applications Are Clamshells Used For?

Clamshells are most popular in the food packaging industry. They are used for packaging items such as sandwiches, pies, cookies, bread, burgers, BBQ ribs, frozen lobster tails, salads, and various other types of food products.

You can find clamshells in many different retail settings. These include markets and food stands. But they are also becoming popular in food trucks and catering services. While clamshells are primarily used in the food packaging industry, you may find some types of this packaging in hardware stores.

Nails, screws, and small home repair tools are sometimes packaged in hybrid carded packaging materials. These containers blur the lines between clamshells and blister packs.
