They are made from two identical plastic shells
Clamshells are a type of packaging that resemble their ocean-dwelling namesakes. They are commonly used in food packaging, including for sandwiches, salads, and fruit and vegetables. Clamshells are also used in hardware stores for packaging small items such as nails and screws.
Clamshells are made from two identical plastic shells. These shells are attached on one side and have tabs on the other side. When the sides are pressed together, snaps form a seal, some of which are harder to unfasten than others. The shells can also be heat-sealed, making them impossible to open without tools.
Clamshells are made from a variety of plastics, including polystyrene, polyester, PVC, foam sheets, PET (polyethylene terephthalate), and RPET. They can be created through thermoforming or injection moulding.
Clamshells are technically recyclable, but few are recycled in the US. This is due to the difficulties of processing clamshells and bottles together, as they have different bulk densities. Clamshells are also hard to identify among other plastics, and they break into different-sized chips and melt at different temperatures.

Clamshells are hard to recycle
Clamshells are a type of plastic packaging commonly used in food packaging applications. They are made from two identical plastic "shells" that fit around the product and are attached on one side with a hinge, with snaps or tabs on the other side that form a seal. Clamshells are used to package a variety of food products, including sandwiches, salads, desserts, seafood, chicken wings, spinach, strawberries, cherry tomatoes, and eggs. While clamshells are technically recyclable, they are difficult to recycle in practice for several reasons.
Firstly, clamshells are often made of Polyethylene-terephthalate (PET) plastic, which has a #1 symbol on it and is usually one of the few plastic numbers accepted by curbside recycling programs. However, clamshells are an exception to this rule, as many curbside recycling services do not accept them. This is because clamshells and drink bottles, while both made of #1 PET plastic, have different densities due to their distinct manufacturing processes.
Additionally, clamshells break into different-sized chips than plastic bottles, melt at a different temperature, and often have strong adhesives that are hard to remove. Blending clamshells and bottles together can result in a lower-quality recycled product. Therefore, recycling facilities prefer to handle only #1 PET bottles or a mix of bottles and a small number of clamshells to maintain the purity of the end product.
Furthermore, clamshells are inherently challenging to sort once they reach the recycling facility. Due to their lightweight nature, flattened clamshells behave like paper on the sorting conveyor belt, making them difficult to separate from other materials. Even facilities with advanced sorting machinery and a large number of employees struggle to differentiate clamshells from other types of plastic at the volume and speed they receive and process them.
Another issue with recycling clamshells is that they often have labels with strong adhesives that are difficult to remove. When processed at material recovery facilities (MRFs), operators and sorting equipment find it challenging to differentiate clamshells from other similarly-shaped containers made of different plastics and from the more desirable PET bottles. As a result, the final PET bales meant for shipping and further processing can become "contaminated" with the plastic clamshells, reducing their market value.
Overall, while clamshells are technically recyclable, they are difficult to recycle due to the specific nature of the materials used, the challenges in sorting and processing them, and the potential contamination of other recycled materials. These issues need to be addressed to ensure that clamshells are properly recycled and do not contribute to plastic waste and environmental harm.

Clamshells are single-use plastics
Clamshells are a type of plastic packaging commonly used for food products. They are made from two identical plastic "shells" that fit around the product and are attached by a hinge on one side. Clamshells are typically used for packaging sandwiches, salads, fruits and vegetables, seafood, chicken wings, and other types of food. They are also used for packaging hardware items such as nails, screws, and small home repair tools.
Clamshells are often made of plastic, but they can also be made from other materials such as styrofoam, paperboard, cardboard, and recycled paper. Plastic clamshells are usually made from PET (polyethylene terephthalate) plastic, which is technically 100% recyclable. However, clamshells have been voted the worst design ever and have spawned the term "wrap rage" due to the difficulty in opening them. The process of opening clamshells often requires ingenuity and effort, and thousands of people seek medical treatment each year for cuts and injuries sustained while attempting to open them.
Despite being technically recyclable, clamshells are often not recycled in practice. They are a single-use plastic, and few are recycled in countries like the United States. This is due to several reasons, including the difficulty in differentiating clamshells from other similarly shaped containers made of different plastics, the strong adhesives used on clamshells that are hard to remove, and the different densities and melting temperatures of clamshells compared to plastic bottles. The recycling process for clamshells can be complicated and costly, and many recycling programs and facilities do not accept them.
The difficulty in recycling clamshells has led to shiploads of U.S. waste plastic being sent to countries like Thailand, India, and Indonesia, where waste management practices may be inadequate. Additionally, the burning of plastic waste, including clamshells, releases CO2 and toxins into the environment. To address the issue of clamshell waste, it is important for consumers to avoid purchasing products packaged in clamshells whenever possible and to properly dispose of or recycle them when they cannot be avoided.
While some alternatives to plastic clamshells exist, such as paperboard or molded pulp, these options may not always be suitable for all products. Paperboard clamshells, for example, can be difficult to recycle if they are contaminated with grease, sauce, or other food stains. As such, it is important for manufacturers and the plastics industry to increase their use of recycled plastic in packaging and improve the recyclability of clamshells to reduce their environmental impact.
