InSight is an award-winning packaging system that combines printed plastic sleeves and injection molded plastic end caps to produce a very distinctive visual package. Injection molded end caps hold products securely and attach to sleeves using a unique locking feature. Undercuts molded into the end caps engage in-folded, die-cut tabs on the sleeve to join the components together. End caps can be designed to lock securely to the sleeve or twist off easily.
InSight packages are essentially tubes, where the end cap shape determines the profile of the package. Although "cat's eye" is most common, InSight packages can be designed in a variety of profiles, including oval, round, rectangle, square, trapezoid, etc.
