Klearfold® Keeper Clear Packaging System.

When production volumes don’t justify the investment in injection molding tools, our patented Klearfold Keeper clear packaging system offers distinctive structural designs. 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.
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.
