Keystone Folding Box Co., a designer and manufacturer of paperboard packaging solutions, introduces an F=1 version of its Key-Pak child-resistant blister card suitable for use with cold-form foil (Alu-Alu) blisters. Key-Pak offers a customizable, fold-over design. The solution achieves the category’s highest child resistance rating of F=1 while remaining easy to open for seniors and users with dexterity challenges. The new Alu-Alu version is suitable for products requiring high barrier protection, as well as delicate oral solid dose products requiring a peel-back opening to prevent physical damage to tablets or capsules. Key-Pak contains less plastic than bottles or amber vials. Its back-side “zipper” design helps provide safe and clean removal of each dose, while its broad, flat surface gives ample room for usage instructions or drug information.
