Why Clamshell Containers Are So Popular?

As we mentioned at the beginning of this blog, the clamshell containers are so popular. Here is the reason:

High Visibility

Most of the clamshell food containers are transparent, such as plastic material, PLA. Such kind of food containers allow customers to see the food inside without opening it. This visibility helps consumers to assess food freshness, portion, and appearance.

As retailers, such visibility can help you catch customers’ attention, such as colorful salads and neatly arranged pastries.

Protection & Safety

Rigid clamshell containers provide strong protection to the food during transport, storage, and handling.

Most of the food clamshell containers can be sealed or have tamper-evident closures, which tell customers the food inside has not been tampered with. This is especially important for the pre-packaged food, deli products, or ready meals.

For the seller, such packaging can reduce returns and complaints caused by packaging damage or food contamination.

Convenience

For consumers, clamshell take out containers are easy to carry and allow re-closing after opening. This is very useful for takeout or on-the-go meals.

Versatility

The clam shell food containers can be produced in different sizes and shapes, suitable for packing various foods, such as berries, salad, cut fruit, ready-to-eat meals, sandwiches, pastries and baked goods, deli meats and cheeses, snacks, and more. This wide applicability makes it the first choice for many food categories.

High Cost Performance

The huge market demand for clamshell boxes has significantly reduced manufacturing costs, thereby lowering costs for restaurants, retailers, and food producers.

Keep Food Hygienic & Fresh

Most clam shell packaging has rigid sealing and protective structure, which helps keep the food fresh and reduces contamination risk.

The material used to produce clamshell container is moisture-resistant and grease-resistant, which helps to reduce the risk of leaks.

How Clamshell Containers Are Made?

Here, we will introduce the production process for plastic clamshell containers and bagasse clamshell containers.

Plastic Clamshell Containers

Thermoforming is the primary method used to manufacture plastic clamshell containers because it is fast, efficient, and highly customizable. The production process is as follows:

Creating Plastic Sheet

• Food-grade PET or PP pellets are melted in an extruder.
• The molten material is pushed through a die to form a continuous, uniform sheet.
• The sheet is cooled, rolled, and precisely controlled for consistent thickness.

Heating, Forming & Shaping Clamshell

• The plastic sheet is reheated until pliable.
• Vacuum forming pulls the sheet onto the mold; pressure forming adds air pressure for sharper details.
• Precision molds define the container’s size, shape, hinge, and locking features.

Trimming & Finishing Container Edge

• Formed clamshells are trimmed from the sheet.
• Edges are smoothed, hinges defined, and locking tabs ensured to close securely.
• Excess material is collected and recycled back into production.

Bagasse Clamshell Containers

The bagasse clamshell containers come from the sugarcane waste. Let’s take a look at how they can produce to a food container.

Collection & Preparation of Raw Material

• Bagasse fibers are collected from sugar mills.
• Fibers are cleaned to remove dirt, sugar residue, and impurities.

Turning Fibers into Slurry

• Cleaned fibers are mixed with water.
• The mixture is mechanically broken down into a uniform pulp slurry.
• Excess impurities are filtered out.

Forming / Molding the Shape

• Pulp is deposited into a forming mold shaped like the clamshell.
• Vacuum suction pulls fibers tightly against the mold surface.
• Excess water drains through micro-perforated molds.

Hot-Pressing (Heat + Pressure)

• High temperature + pressure compress the shape.
• Water is removed rapidly.
• The structure becomes firm, smooth, and rigid.

Drying & Curing

Depending on factory setup, drying may involve:

• Hot-air ovens
• Chamber drying
• Continuous conveyor drying

Trimming & Edge Finishing

• Laser cutters or steel dies trim excess fiber.
• Edges are smoothed.

As we know, packaging for the bakery is very important, because we need to:

1. Prevent baked goods from contamination.
2. Maintaining the freshness of baking.
3. Establish a good image for your own baking brand in front of customers.

But, disposable packaging pollution is very serious, and the bakery packaging is not a small consumption, so we need to turn our direction to eco friendly packaging for below reasons:

Environmental Benefits

Plastic and other non-recyclable packaging materials make our environment’s natural condition very serious, all the packaging waste throw away, and they flow into the ocean, are buried in the soil, or accumulate in landfills. But, if you use eco friendly packaging for the bakery, you are contributing to protecting the environment. These materials are recyclable, biodegradable, and compostable.

Business Advantages

Nowadays, consumers are becoming more and more aware of environmental protection, and most consumers prefer bakeries that use environmentally friendly packaging. On the other hand, using environmentally friendly packaging can also enhance consumers’ awareness of your bakery brand and increase their favorability.

Compliance with Regulations

Many countries and regions are banning plastic and foam packaging materials, and they tend to encourage businesses and individuals to use biodegradable and compostable packaging materials. So, policies will become increasingly stringent regarding the use of environmentally unfriendly disposable packaging.

Types of Eco Friendly Bakery Packaging

Now, let’s have a look at different bakery packaging and see which one is suitable for your needs. Which one is your eco friendly choice?

Paper Based Packaging

The paper based packaging can be made into various types:

Cardboard Boxes

The cardboard boxes have various forms, like a standard cardboard box, a box with a visible window, and a cable box.

Standard Cardboard Box

The standard cardboard box is featured like a paper box. Normally, this box has a solid color, such as white. The box design is foldable, so it is convenient for shipping, delivery, and assembly. You can custom stickers for this box or custom stamps for this box, but if you want to print on the box directly, you need to talk with the box manufacturer directly.

The standard cardboard box is generally used for packing cakes, cupcakes, and different pastries.

Box with Visible Window

The box with a visible window is also made from cardboard, and at the top of the box, there is a clear plastic window for consumers to see what’s inside. This kind of packaging is suitable for gift-giving. This box is usually used for packing eclairs, tarts, decorated cupcakes, artisan bread, and pastries.

Cable Box

The cable box is also made from cardboard, but the design is unique, since it has a handle at the top of the box. Such a design is easy to carry and suitable for packing the small to medium sized sweets, like buns, rolls, and cookies.

Bread Bags

The bread bag is made from kraft paper, it is generally brown in color and used for packing croissants, long bread, and other various long pastries.

The cardboard boxes and bread bags are considered eco friendly bakery packaging, their sizes, colors, and shapes can be customized. Cardboard is an eco friendly material, since it is recyclable and biodegradable. Above three types, only the visible window, which is generally made from plastic, this part is not eco friendly.

Compostable and Biodegradable Materials

The compostable and biodegradable materials used for packing the bakery generally mean sugarcane containers and cornstarch containers. Let’s have a look.

Sugarcane Containers

Sugarcane containers are made from the bagasse, which is the byproduct of sugarcane. Bakery packaging made from this material is 100% eco friendly, biodegradable, and compostable. Generally supplied in clamshell shape, but can be customized into any size and shape you want, suitable for packing donuts, danishes, and cakes.

Cornstarch Containers

Cornstarch containers are made from corn starch, a sustainable and renewable material. The bakery box made from this material is also biodegradable and compostable, since the raw material is 100% natural. Cornstarch containers can be made into different shapes and sizes to fit your different sweets.

Reusable Packaging Materials

Reusable packing materials can also be regarded as one of the eco friendly packaging materials. In the bakery shop, in addition to short-shelf-life bread and cakes, there are also biscuits, small cakes, and a variety of small desserts with a longer shelf life. These items are often packaged in reusable packaging. The reusable packaging materials are:

• Glass jars
• Reusable tins
• Metal boxes

Plant-Based Plastics

Traditional plastic used for packing bakery products is always considered not environmentally friendly, but the PLA, the plant based plastic is compostable. The bakery packaging box made from this material is clear and can be used to display the food inside the box.

Factors You Need to Consider When Choosing Bakery Packaging
