Food Clamshell Packaging

Food manufacturers have many options when it comes to food packaging containers, but none quite like the classic clamshell. For everything from sandwiches to snacks and muffins to macaroni salad, plastic clamshell packaging from EasyPak keeps their food fresh, delicious, and safe from tampering and contamination.

Food Clamshell Packaging

EasyPak, founded in 2004, has grown to become one of North America’s leading resources for innovative solutions in thermoformed plastic food packaging.

Since recently joining forces with three other successful plastic thermoforming companies – Tray-Pak (Reading, PA), Nuconic Packaging (Vernon, CA), and James L. Villa, Inc. (Oldsmar, FL) – EasyPak has the ability to offer a wide spectrum of technical and manufacturing capabilities across a national footprint, with facilities from coast to coast.

Our speed to market, breadth of materials, prototype and engineering technology, and production versatility are all critical factors in what makes EasyPak the most reliable choice for your plastic packaging needs.

What is Clamshell Packaging?

The classic clamshell is a clear, rigid, one-piece container that consists of two bowl-shaped halves joined by a hinge that allows it to open and close. Some thermoformed plastic clamshell containers have a single hinge, while others feature a multi-hinged design.

Most clamshell packaging is sealed with self-locking tabs, button snaps, or a friction fit.  When heat-sealed, the containers are leak-resistant and tamper-resistant, and your products will be protected from damage and contamination. Also, with the clamshell package’s resealing capabilities, food can be preserved for a long time after opening.

Clamshell packaging also simplifies package labeling for conveying important information about products to consumers, such as brand identification, nutritional information, ingredient declaration, cooking instructions, and pricing.

Material Options

Packaging performance depends on design and function, and each application has an optimal food-grade material choice. EasyPak’s engineers will help you design the optimal package for your application and choose the right material, from traditional plastic polymers to new eco-friendly alternatives such as FDA PCR-APET (post-consumer recycled APET).

Here is a look at some of our materials and how they are commonly used in food packaging applications:

High-Density Polyethylene (HDPE)

HDPE is the most widely used plastic for bottles and containers. Unpigmented bottles are translucent and are often used to package products with a short shelf life, such as milk. HDPE’s high tensile strength and excellent crack resistance makes it well-suited to clamshell containers and trays. It is recyclable.

Polyethylene Terephthalate (PET or PETE)

PET is a clear, strong, lightweight, and completely recyclable plastic that has become the world’s preferred packaging material for foods and beverages. It is used for many foods, and special grades are used for carry-home food containers and prepared food trays that can be warmed in the oven or microwave.

Amorphous Polyethylene Terephthalate (APET)

APET is strong and pliable and offers superior leak resistance. It can be coated with anti-fog material to maintain clarity when used in cold cases. It is popular for platter domes, cake and pie packages, and for sandwiches, salads, bakery, deli products, and fresh produce.

Polyethylene Terephthalate Glycol Modified (PETG)

PETG is very similar to PET in properties and uses. The main difference is the addition of a Glycol modifier (the “G” in PETG) that removes the hazing effect during the heating of PET. It is optically clear and recyclable.

Polypropylene (PP)

PP is found in flexible and rigid packaging. It is strong, recyclable, and has a high melting point, making it good for hot-fill liquids. Common packaging applications include containers for yogurt, margarine, cream cheese, sour cream, takeout meals, and deli foods.
