HLP Klearfold recently purchased the worldwide patents for the InSight visual packaging system from ASG (the AGI Shorewood Group), with whom they previously had an agreement to license InSight. The system combines printed plastic sleeves and injection molded plastic end caps to produce a very distinctive visual package.
The sleeves are essentially tubes with the shape of the end caps determining the cross-sectional profile of the package. The end caps attach to the sleeves using a unique locking feature. Undercuts molded into the end caps engage die-cut tabs on the sleeves to join the components together securely. Packages can be designed so that end caps either lock permanently to the sleeve or twist off easily.
Insight is most suitable for larger volume applications, because up-front tooling costs for injection molded components can be expensive; production runs of 250 thousand pieces or more are typical.
Procter and Gamble, Kao Brands, and Johnson & Johnson have all used this iconic package, for some of their most memorable product launches.
For smaller volume applications, HLP Klearfold's patent-pending Klearfold Keeper, which offers non-traditional shapes at less cost. Like InSight, Klearfold Keeper uses printed plastic sleeves, but the sleeves lock to cost-effective vacuum-formed trays, rather than injection molded components.
A thumb-notch perforation in a corner of the Klearfold Keeper sleeve provides a unique, easy-opening feature. Removing the thumb-notch also removes the lock, allowing the tray to be easily disengaged from the sleeve.
"InSight and Klearfold Keeper are perfect, complementary packaging systems," says Steve Frazier, president, HLP Klearfold. "Both packages offer similar unique geometries and a very distinctive shelf presence, but have different production volumesweet spots. Klearfold Keeper is more cost effective for lesser volume applications while InSight is more cost effective for high volume."
