What are Clamshell Food Containers?


As the name suggests, clamshell containers are a form of packaging that close just about as tight as the proverbial oceanbed clamshell.

Hinged vs Non-Hinged Clamshell Containers


When it comes to clamshell containers, there are two basic types: hinged and non-hinged.

When you are making a decision about your packaging requirements, your specific use case and budget resources will dictate whether you need a hinged or non-hinged version.

From the end customer’s perspective, you will need to consider the type of foodstuffs the packaging will contain, how perishable those foodstuffs might be, and the ways in which your clamshell containers may be transported or displayed on the journey between packaging and purchase.

From your perspective, you will have several things to consider too.

For example, while hinged containers may win on convenience, the fact that they are a little more production-intensive — and therefore more expensive to produce at scale — may mean they are a little less suitable for your particular budget.

If variations in closure design is important to you, then the hinged option provides more options and flexibility.

The table below gives a brief overview of the differences in production process between hinged and non-hinged containers.

Innovative Design of Snap Buttons for Food Clamshell Containers


From product design to brand marketing, you will already have considered all the many different ways of making your product stand out in the competitive global marketplace. And if you choose the hinged container option, there’s no doubt that the versatility and flexibility of container closure styles gives you an extra opportunity to really differentiate your product from its neighbors on the shelves.

Something that many people might not consider, which can have a significant subliminal positive effect on the customer, is the shape and size of the snap button on your product container. This can help give your product the “Wow Factor” from the first time customers take your product home.

While non-hinged containers come with separate bottom and lid, hinged clamshell containers are designed with a variety of different closure styles and can give you the added advantage of extra product differentiation.

So-called “snap button locks” are one such element of clamshell container design which can really help your product stand out from the rest.

Snap button locks, which hold the clamshell closed, come in various sizes and shapes, including oval, triangular and rectangular.

The good news is that you have full capability to customize your snap button locks on your product at the mold design stage, and our team will be on hand to help you through that process to ensure that your final design meets your needs perfectly.



Examples of Different Snap Buttons Designs

  • Rectangle-shaped snap button locks

    The button shape is designed as a rectangle and is usually on the front edge of the clamshell containers for easy opening and closing.

    The button shape is designed as a triangular or oval, and they are placed at the four corners of the clamshell containers.
    There’s a gap on the bottom cover which can be directly pulled to open.

Design Embossing for Unique Clamshell Containers


The design phase for your product containers can also include design embossing, or what might be described as “bumps” on the container. This is something that you will bear in mind during the thermoforming mold design process, and which our team can advise you on also.

For example, the clamshell container closure experience will be different if the bump shape design changes or the angle of the barb. With different designs of barbs, such as different quantities, positions and angles, you could build different clamshell food containers.
