The Clamshell Basics

  1. Clamshell packaging secures product(s) between two hinged sheets of thermoformed plastic.
  2. The plastic clamshell encloses the product on both sides and the plastic flanges (edges) can be heat sealed together.
  3. Clamshells may be custom molded to follow the contours of an item, or serve as a clear plastic container for holding a number of small loose pieces together.
  4. Tri-Fold or footed clamshells offer maximum versatility in merchandising. These packages can hang from a hook, stand alone on a shelf, or sit upright within a display or club store pallet.
  5. A printed insert card sells the product with compelling graphics and product information while the clear plastic provides excellent visibility. When sealed on all edges clamshell packages are especially tamper and theft resistant.
  6. Packaging is re-closable and reusable if left unsealed.
  7. Clamshell packaging is especially effective packaging option for heavy products, or items like electronics that are a target for theft.

Plastic Clamshell Packaging Advantages

What are the advantages of using clamshell packaging for your products? Below are just some reasons why you should opt for plastic clamshell packaging:

Provides a Clear Product Display

Clamshell packaging is one of the best ways to showcase the quality of your products, further helping them along in their purchase decision. In fact, it is estimated that over 50% of shoppers agree that it is essential to see a product through its packaging. In addition to showing the quality of your product, plastic clamshell packaging also helps to give your products a fresh or clean appearance. For example, in the case of food products, approximately one-third of shoppers determine how fresh a product is by how it appears rather than by the use-by date.

Conveys a Higher Quality Product

The packaging of your product can really make or break a sale. In addition, using plastic clamshell packaging conveys high quality. They provide a clean look and feel, are highly durable, are well sealed and can be made from various thermoformed materials. Another benefit of using clamshell for your products is that its a recyclable material. This is yet another factor which shoppers pay attention to. On the whole, clamshell packaging tends to convey a more high quality product, and helps to establish trust with your buyers.

Provides Better Product Protection

Another leading reason why people opt for clamshell packaging is that it provides overall better protection for their products. Quality sealing of the clamshell helps to prevent item theft. With clear, protective, and long-lasting thermoform materials, clamshell packaging provides security to lessen the chances of breaking into the packaging/shoplifting. Additionally, clamshells provide longer shelf life and extended packaging performance. As mentioned already, clamshell packaging is exceptionally durable, also helping to maintain the quality and freshness of your products. Clamshell package products should be “tamper evident,” so that consumers recognize that the package has been cut, broken, or otherwise tampered with.

Clamshell Packaging Security Benefits:

  • Quality designs with advanced security features
  • Professionally sealed to resist theft and tampering
  • Increased profits by lessening the chances of theft
  • Improved retailer’s confidence in the sales of product and integrity of the business
