Tried-and-True Tubes

Tubes are improving in the areas of child resistance, tamper evidence, and dispensing capability.

Tubes are an old, reliable packaging format, but even this industry staple is undergoing renovation. Developing child-resistant closures is a challenge because tube materials are designed to be squeezed; however, manufacturers have overcome this difficulty to offer child-resistant and tamper-evident tubes.
