What is Clamshell Packaging? A Commercial Food Packaging Guide

Publish Time: 2024-09-10     Origin: Site

Clamshell packaging is a one-piece, hinged container used extensively in the foodservice and retail sectors for its superior protection and secure closure. While traditionally made from oil-based plastics, the industry is rapidly shifting toward sugarcane bagasse pulp clamshells due to their natural breathability, which prevents fried foods from becoming soggy—a common failure of plastic. For B2B procurement, modern clamshells must balance stacking strength with eco-compliance. Bagasse alternatives offer a high thermal range, providing a versatile, biodegradable solution that meets strict international plastic ban regulations without compromising on structural integrity.



What is Clamshell Packaging?

Clamshell packaging comprises two halves connected by a hinge. It is named after its clamshell-like design. Clamshell containers are made of rigid materials to encase and protect the products. Their tamper-proof structure keeps your products safe while handling.

It features a snap‑lock design for tamper resistance and prevents accidental opening during transportation. In the food industry, it is the most popular form of disposable takeaway packaging for meals, burgers, salads, fruits, and baked goods. The global clamshell packaging market is valued at $9.1 billion in 2024. This market value is expected to reach $12.2 billion in 2034.



Different Types of Clamshell Packaging

You can find various types of clamshell packaging based on the manufacturing material. Here are some common types of clamshell packaging types:


1. Thermoform Clamshell Packaging

Thermoforming is a perfect way to manufacture custom clamshell containers. They are made to fit your products, making them a fantastic way to market your product. Thermoform clamshell containers have been in use since 1961. However, advanced technology has improved their protective properties, making them more functional. Thermoform packaging is an extensive market. According to an estimate, global thermoform packaging was valued at $51.96 billion in 2023 and is expected to become $88.50 billion by 2030.

You can manufacture thermoform clamshell packaging with 3D printing or CAM/CAD design. In-house tooling allows you to make customized containers. You can find fold-over, two-piece, and tri-fold freestanding thermoform clamshell packages.

Clamshell containers manufactured from thermoform provide exceptional protection for your products. They also offer visibility, allowing customers to see the product inside. Moreover, their robust structure provides stability for packing light to heavy items.

Thermoform clamshell packaging is a unique way to catch customers’ attention. Various die-cuts and intricate shapes enable you to craft appealing containers. You can also insert printed cards to enhance their elegance.

However, it is important to note that most thermoformed clamshell containers are not biodegradable, involve high mold costs, and are not environmentally friendly.


2. Plastic Clamshell Packaging

Plastic clamshells are extensively used for disposable and reusable packaging. Various types of plastics are used for making these packages. PET, PVC, polystyrene, and ABS are common types of plastics for packaging. PET plastic is recyclable and mostly utilized for manufacturing clamshell containers.

Plastic clamshell containers are lightweight. This feature allows you to conveniently ship your products. The transparency allows customers to view the product without opening the packing. It boosts their confidence in the product.

Manufacturers have been using plastic for decades. However, its high environmental impact is raising concerns about its use. The Waste and Resources Action Programme reported that plastic contributes 1.8 billion tonnes of carbon per year. It comes from the production, usage, and disposal of plastic. Despite its impact, it is still used for packaging food and retail items.

3. Paperboard Clamshell Packaging

Paperboard clamshell containers are getting popular due to their low carbon footprint. They are replacing plastic packaging in various industries. Their structure is quite similar to plastic clamshells, having two shells that are connected on one side. The other side has an interlocking tab that closes the container.

Kraft paper clamshells are often used for bakery products and light takeaway meals. Not ideal for oily or liquid-heavy meals without additional coating. Recyclable paperboard clamshells are a preferable choice for environmentally conscious customers.

They are made from recyclable materials but are not the best eco-friendly option. They are recyclable only if they are not stained with any kind of grease or contaminants. Some manufacturers use a wax coating to prevent the food stains from contaminating the paperboard.

4. Bagasse Clamshell Packaging

Bagasse is a plant-based material used to manufacture biodegradable clamshell packages. Although bagasse clamshell containers resemble Styrofoam, they are a sustainable option.

Disposable bagasse containers are durable and moisture-resistant. These features make them suitable for various applications. The demand for bagasse clamshells is escalating as customers prefer eco-friendly packaging.

Bagasse clamshells can withstand temperatures ranging from -20°C to 120°C, making them suitable for hot foods and microwave-safe. This has made them extremely popular for hot foods such as hamburgers and fried foods.

They do not contain any harmful substances and have less environmental impact than plastic and other materials. In addition to its sustainability, bagasse packaging repurposes agricultural waste, further reducing its environmental footprint.
