Klearfold ® Keeper
When production volumes don't justify the investment in injection molding tools, our patent-pending Klearfold Keeper offers distinctive structural designs, similar to InSight, but at less cost. The Klearfold Keeper clear packaging system consists of a clear plastic sleeve that's designed to lock to a vacuum-formed tray or clear plastic clamshell. Vac-trays and clamshells are fabricated to conform to the shape of the product and to the desired cross-sectional package profile.
Klearfold Keeper offers easy and efficient hand-filling… the product is loaded into the vac-tray and the sub-assembly slides into the clear plastic sleeve. In-folded tabs on the sleeve engage a specially designed flange on the vac-form, locking the two components securely together, without the need for wafer seals or the use of sonic, RF, or heat sealing equipment.
A thumb-notch perforation in a corner of the clear plastic sleeve provides a unique, easy-opening feature. Removing the thumb-notch also removes the lock, allowing the tray to be easily disengaged from the clear sleeve.
