Non-tear Design Clamshell Packaging is a design in which the bottom and lid do not separate when the box is unfolded.

Protective Design Clamshell Packaging

Protective clamshell boxes, also known as anti-theft clamshell boxes, are a packaging design used to effectively prevent unauthorized opening of a plastic box, often using an anti-theft clasp or chain as the anti-theft mechanism.

How to Select Clamshell Packaging?

How do you go about choosing a clamshell container? Choosing a clamshell container is a task that requires careful consideration, and it involves a variety of factors.

The first thing you should consider is the capacity of the clamshell container. Ensure you know what to think to fit the items in the clamshell container.

Secondly, you should consider the type of clamshell container and what kind of items you want to use the clamshell container for: meat, fruit, baked goods, deli items, and so on. Choosing what to put in the clamshell container requires consideration of the material: PET, PVC, PP and so on.

In addition, you need to consider whether the product is qualified, has passed the relevant verification, has the appropriate certificates, is biodegradable or sustainable, etc. Also, we need to consider local policies, such as whether there is a plastic ban, etc. The last is the personalized demand, whether it is necessary to customize the label and logo or whether it needs to be customized for your needs.  The ultimate guide to clamshell packaging will tell you how to select clamshell packaging.

Step 1: Consider Storage Requirements

The first step to consider is the size of the capacity of the clamshell container. It depends on the size of the item you want to hold. For example, if you’re going to hold a whole apple, you can choose one or more entire clamshell containers. If you cut the apple into strips, you will have more options and can select different sizes of clamshell containers. This step also allows you to consider the shape of the clamshell container: rectangular, round, etc.

Step 2: Choose the Type of Food Product

The second step is to consider the type of clamshell container and what items you need to use the clamshell container for. Fresh frozen food, fruits and vegetables, baked treats, cooked food, etc. Once you have a clear idea of what you need to pack, you need to consider the material of the clamshell container, whether it needs to be biodegradable or sustainable, and whether it needs to be anti-theft.

If it is fresh frozen food or cooked food, we recommend you choose the anti-theft clamshell containers; if it is fruits and vegetables, we recommend you select the clamshell containers with holes for ventilation; and if it is baked goods, we recommend clamshell containers without holes to prevent mosquito bites.

Step 3: Accord with Regulatory Compliance

Clamshell containers must follow a series of regulations and standards in the design and production process to ensure that safety, environmental protection, etc., meet the relevant requirements. Therefore, the third step you should do is to consider the qualification of the clamshell container, checking whether it complies with the food safety regulations, whether it complies with the environmental rules, whether it has passed the relevant verification, whether it has the relevant qualification certificates, etc.

Step 4: Need or not Personalized Demands

The last step is to consider the need for personalization, whether you need custom labels, logos, etc. Whether there is a need for number requirements, such as 10 egg trays, 12 egg trays, or other different numbers. You can also consider customization if you don’t find a clamshell container that meets your needs.
