Looking sharp on the shelves is also a priority and the C-PAK has the ability to adapt to multiple presentations. It can hang on a peg board, stack in a well or lie on its side. Colorful labels easily adhere to the package's smooth outer cover enhancing the product's brand power on supermarket shelves. Compared to form/fill/seal packs, the C-PAK is extremely durable and will maintain its shape through the transportation process and beyond. Its non-barrier lid can even be recycled.


The patented C-PAK utilizes an inside closing lid with the ability to close on three surfaces instead of one narrow area. This technique creates a stronger seal than an ordinary over cap. State-of-the-art tray sealing capabilities allow for an extremely tight tolerance between the lid and tray which extends shelf life. After first time use, consumers know exactly when the package is closed properly because they hear a clicking sound notifying them that the freshness has been locked in.
