WHY ALUMINIUM? Aluminium Collapsible Tubes   This statement is unconditional. Air does not pass through the wall of Alucan's/Alupak's aluminium container, rigid or flexible. The aluminium tube gives you maximum shelf-life. The aluminium tube can be designed to be non-reclosable. Once opened, it becomes disposable after use and can be recycled. Alucan/Alupak will even take back and recycle the aluminium. The tamper-resistant requirements for products that need that extra-special security can be designed into the aluminium container using our unique neck and tip constructions. Talk to us about any of the features that can help you market your products better.
