Retail Clamshell Solutions

Retail clamshell packaging

The preferred packaging method for:

  • Product display, visibility and branding.
  • Product containment, organization and protection.
  • Security and theft deterrence.
  • Cost effectiveness and sustainability.

Retail clamshell packaging fully encapsulates the product while still providing complete product visibility. The typical clamshell design consists of a single hinge in the center of the package which folds-over to close and encase the product(s).  The clamshell generally has a formed full perimeter snap, button snap or a combination of both features for package closure.  Some variations to the typical clamshell include:

Tri-fold or “Tent-style” Clamshell

This type of clamshell incorporates two hinge points in the clamshell package.  When closed, the two hinges create 3 sides of the clamshell which come together to encase the product. This style clamshell is excellent for situations where shelf-standing is required, but they can also be hung on a peg hook display.

2-Piece Clamshell

Technically, this is not really a clamshell as it does not have a hinge.  This style of package generally requires a secondary seal method and lends itself very well to automated package assembly operations.  When closed and sealed, this package looks just like a clamshell due to the full encapsulation of the product.

Retail Clamshell Closure Methods

Please contact us for assistance.  We can help you select the best option to meet your requirements.  Here are a few of the more popular options:

  • Formed feature designed into the package: friction fit, snap feature, button, etc. This method requires no special equipment or tooling for the package assembly process and allows for easy reusability of the clamshell.  However, some retail outlets require a sealed clamshell so that the package is not opened in the store and to deter theft.
  • Radio Frequency (RF), Ultrasonic, Heat Impulse and, Adhesive sealing.  These methods work well with low and high volume automated packaging operations.  They also provide a permanent seal.
  • Pressure sensitive tape, labels and shrink bands.


Materials typically used for retail clamshells include: PETE, PVC, PETG.  Recycled, blends, Virgin, FDA Grade, and Medical grades available.  Static control (Anti-stat, ESD, Conductive) materials available. View complete list of commonly used materials.
