Clamshells are a type of carded packaging. Carded packaging is a collection of packaging materials that generally feature two components. These components included backers made from plastic, skin-board, or paperboard and front-facing materials made of various plastic formulations. They are commonly used in food industry, hardware industry, etc.
Types of Clamshell Packaging
Thermoform Clamshell Packaging
Thermoform clamshells are designed and created with CAD/CAM design and 3D printing. Thanks to in-house tooling, these clamshells can be custom-made with fast delivery and ultra-high quality. Thermoform clamshells are available in three varieties, including two-piece, fold-over, and tri-fold freestanding models. These clamshells are made from various materials, including PVC, RPET, and PETG plastic. They provide enhanced stability for light to heavy products.
Plastic Clamshell Packaging
One of the longest-running and most well-known forms of clamshell packaging is plastic clamshells. These have been on the market for decades and are still extremely popular with food manufacturers and retailers alike. Most often featuring two interlocking "shells" made from PET (polyethylene terephthalate), plastic clamshells are a common sight wherever food is sold. They are used for packaging many types of food, including sandwiches, salads, desserts, seafood, chicken wings, and various other types of food.
Paperboard Clamshell Packaging
Paperboard clamshells, like their plastic counterparts, feature two shells that are connected on one side while featuring interlocking tabs on the other. Recycled paperboard clamshells are an even more popular variant of this type of clamshell packaging. They are made of recycled materials and are a big draw for businesses with earth-conscious consumers. Although, they are not exactly "green." This is due to the fact that these containers, once stained with grease, sauce, or other similar contaminants, cannot be recycled. Paperboard clamshells can be found in supermarkets (primarily for raw egg packaging), food trucks, restaurants, BBQ joints, eateries, caterers, serve-yourself hot food bars, and various other types of food retailers.
Plant Fiber Clamshell Packaging
These unique clamshells are most commonly made from wheat grain and chaff, perfect for hot and cold food packaging applications. Unlike other bio-based clamshell products, these containers are soak-proof and resistant to water and liquids. Like most clamshells, these carded packaging supplies feature two shells that are attached on one side while boasting interlocking clasps on the other. You can find these plant-based packaging supplies in various places, including restaurants, supermarkets, food trucks, and beyond.
Advantages of Clamshell Packaging
Protection
Products of all kinds in today's globalized world do a lot of traveling. When your product is transported, you want to make sure it's safe. In the case of food, drugs, or other highly regulated substances, packaging is even more important. Improper packaging can result in contamination, which means a loss of revenue—and can even have legal consequences for your business. Clamshell packaging takes away many of these risks. With secure clamshell plastic packaging, your product is protected from poor storage conditions and improper handling during transport. Clamshell plastic packaging securely seals your product from airborne contaminants, protecting its safety and freshness.
Eye-Catching
Clamshell packaging has an uncomplicated one-piece design that makes it a fuss-free way to get complete enclosure on your products for enhanced protection. Even though clamshell packaging is simplistic by nature, businesses have many options to enhance its aesthetics. Similar to blister packs, companies can insert graphics cards into their retail clamshell packaging designs for added shelf appeal with consumers. Companies can customize their food packaging, as well, by printing the logo or other designs onto the plastic, or manufacturers can dye the plastic itself a particular color. Companies want a way to have their products stand off the shelves and attract the eyes of consumers—clamshell packaging does just that.
Transparent Packaging
Along with an eye-catching design, consumers also want to be assured the products they are purchasing are in the promised condition, without flaws or defects. Many companies often opt for clamshell packaging because of its high-clarity visibility, giving customers that peace of mind they need. When consumers purchase products, be it food or retail, in clamshell packaging, they aren't left wondering what the product inside looks like. Instead, they can examine the package up close to see if it fully fits their needs. Packaging designers can even create strategic cutouts to display particular parts of the product for additional visibility.
Enhanced Security
Even though clamshell packaging is transparent, it is also highly protective. Many companies use clamshell packaging to secure high-end items, including cell phones and cell phone cases. While clamshell packages may also come with another seal, companies still commonly use it in retail settings because it can protect products from outside tampering. These packages are also durable enough to prevent damage and temperature changes during shipping and handling of products. Clamshell provides the same protections for food products, instilling a sense of trust in consumers by letting them know their food is safe to eat.
Clamshells are typically used to package a variety of foods, including sandwiches, all types of pies, cookies, bread, burgers, pastries, frozen lobster tails, salads, and many more food items. Different retail outlets like food carts and catering trucks use clamshells as do markets and restaurants. Sometimes, clamshells made of hybrid carded-packaging materials are used to package nails, screws, and small home repair items. Also, clamshells are used for the storage of toys and other small accessories.
Seal Options for Clamshell Packaging
RF sealing
High-frequency radio waves are used to heat materials and fuse them together creating a consistently strong weld. Typically used to seal PVC clamshells. A fast, strong and reliable form of sealing.
Ultraviolet (UV) Sealing
Applies glue that is cured by UV light in a tunnel to bond clamshell packaging.
Ultrasonic Welding
High-frequency ultrasonic acoustic vibrations are used to seal the two halves of a clamshell, often used to spot weld PET clamshells.
Factors to Consider for Clamshell Packaging
Product Size and Shape
As a business owner using clamshell packaging, it's important to consider the product size and shape. You need to be able to select or design clamshell packaging that fits your products and will be easy to close. If your product is too big or has an intricate design, then it might make the use of clamshell packaging difficult.
Material Durability
Think about the type of material that you'd like to use for clamshell packaging for your products. For example, would you like to use plastic or cardboard for fruit and vegetables? If your business serves hot food, using cardboard packaging would make sense. Opt for clamshell packaging that will be durable enough to store and preserve your products.
Ease of Opening and Closing
Customers find it frustrating if they struggle to open packaging, especially if they have sensory or mobility issues. When selecting or redesigning clamshell packaging, be mindful of this. Ensure that the packaging your business uses for its products is easy to open and close. If it's easy to open, customers will be able to access and use the products quickly. If it's easy to close, customers will be able to protect, store and preserve the products effectively.
Packaging Design and Aesthetics
Many businesses use clamshell packaging to stand out from the crowd, so ensure that you do the same to catch the eye of your target audience. Switch up the design and boost the aesthetics by implementing your brand's identity (colors, copy and logos).
Process of Making Customized Clamshell Packaging
Clamshells are normally created by thermoforming clear plastic. PVC (polyvinyl chloride) is the most often utilized material. Thermoforming involves heating thermoplastic material and covering a mold with it until it cools. In this case, the mold resembles a clam. There are different gauges (thicknesses) of plastic materials available when creating clamshell packaging and the gauge selected is typically based on the item intended to be packaged inside. Whether rolled sheets (thin gauge) or pre-cut stacked sheets are used in the manufacturing process depends on the material's thickness (heavy gauge). The disposable packaging market, particularly in retail marketplaces, is dominated by thin gauge material. After being heated, the material passes onto the forming stage, where it is forced onto the mold under pressure or under a vacuum (vacuum forming). Vacuum forming, in general, refers to all sheet-forming techniques. Greater detail and rough surfaces are produced in the final product thanks to this technique's enhanced pressure and, with the additional pressure used during the forming process, sharp corners can be produced.
