Neopac designs polyfoil dropper tube for vitamin D

Streuli Pharma worked with Neopac to create a safer, more accurate delivery system

Hoffmann Neopac, the wide-ranging packaging company, has partnered with Streuli Pharma AG. The partnership will focus on launching a dropper tube for direct, precision administering of Vitamin D.

Seen as a step up from standard packaging involving glass vials and pipettes, the solution houses vitamin D in a tube with a metered dropper. The result is safer, more accurate dosages.

Babies and toddlers up to 3 years often require daily administration of 400-600 international units (IE) of vitamin D. Considering the product’s frequent use, it makes practical, simple administration all the more important.

For 150 years, Streuli has produced high-quality medicines predominantly for the Swiss pharmaceutical market. With the idea for a precise dropper mechanism to simplify vitamin D dosage for young children, the company tapped Neopac as a partner.

The innovative dropper system dispenses droplets individually by applying light pressure to the tube. Each drop contains 200 IE of vitamin D, which allows easy dosage of both 400 and 600 IE, according to age phase. The glass-free packaging of D3 piccolo allows it to be directly inserted into the mouth, and makes the package more transportable.

Utilising Neopac’s Polyfoil 19 mm dropper tube with screw cap, the solution features a special insert on the dropper mechanism designed for liquid, serums or oily content. This helps to ensure accurate dosing by adjusting the mechanism to the proper bulk texture for ideal drop size.

Polyfoil was an ideal choice for the dropper solution. It is a proprietary blend of materials providing advanced barrier properties for products requiring ample protection against potentially harmful external factors, including moisture and oxygen. Products housed in Polyfoil solutions can enjoy a longer shelf life compared to those stored in conventional polyethylene or polypropylene packaging.

During the collaboration, Neopac saw a need to reconfigure the cap. This is because after the first filling test, the original cap’s fine nozzle risked overtightening the drop thread. This issue was only exacerbated by the tube’s length. Once modified, the finished dropper tube exemplifies an optimised dosage unit capable of precision administration.

The solution made its market debut in spring 2019, and the company says that the consumer feedback has been positive.

We have been working with Neopac for two years on this product, and our collaboration has been extremely productive,” said Rebekka Richartz, Marketing Leader, Human at Streuli Pharma AG. “By jointly developing the Vitamin D dropper tube, we have simplified the administration process for parents, making dosages safer and more precise.”
