Shellpak® packages are award-winning, first-of-their-kind blister packages. Thin, injection-molded, HIPS, “shells” protect fragile pills. A child-resistant push-button technology lets seniors in but keeps children out. And a wide range of configuration options and generous space for graphics open up unprecedented marketing and branding opportunities.

Shellpak® adherence packaging helps deliver pills to patients safely, accurately and in single, controlled dosages.

Proven impact on patient adherence

Manufactures easily

Our patented design comes in a standard configuration that runs easily on most existing line equipment, so manufacturers can maintain efficient, speedy and economical processing on production lines.

Pharmacy-friendly and efficient

Pre-filled medication packages help expedite pharmacist handling, reduce errors and save operational costs. And Shellpak packages stack and store more efficiently than amber vials (standard orange pill bottles).

Child-resistant and senior-friendly

The rigid, plastic shells and proprietary, push-button technology earned our Shellpak packages the highest child resistance rating from the U.S. Consumer Product Safety Commission: F=1. Yet it remains easy for seniors to open.  

Product options

Shellpak is customizable. We offer three standard sizes and a wide variety of shapes and colors. And optional, easy-to-customize, extended content labels provide even more room for bold graphics as well as product and health literacy information.
