InSight® Clear Packaging System
InSight is an award-winning transparent packaging system that combines clear plastic sleeves and injection molded plastic end caps to produce a very distinctive clear package. It 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 packaging can be designed in a nearly endless variety of profiles, including "cat's eye", oval, round, rectangle, square, and trapezoid.
