InSight® Clear Packaging System

InSight is an award-winning transparent packaging system that combines clear plastic packaging sleeves and injection molded plastic end caps to produce a very distinctive clear package. Molded clear plastic packaging has a patented locking feature, where die-cut tabs on the clear plastic sleeves engage undercuts molded into the end caps to join the components securely together. End caps can be designed to lock permanently to the plastic sleeve or to twist off easily.

The shape of the end caps determines the package' s cross-sectional profile; therefore, InSight clear plastic box can be designed in a nearly endless variety of profiles, including "cat's eye", oval, round, rectangle, square, and trapezoid.
