A half-century-old technology is still garnering packaging awards today. High-barrier Polyfoil technology, which protects products from moisture, oxygen and other potentially harmful external factors, is an integral part of three tube-based healthcare products that received high-profile recognition recently, announced Hoffmann Neopac (Thun, Switzerland).
Neopac earned a 2019 World Star award for its Voltaren “No Mess” Tube and Applicator. Developed in conjunction with GlaxoSmithKline and Nypro, the product offers users a more hygienic method of applying pain relief medicine, said Neopac in a press release. Notably, the intuitive pull/push mechanism of the “No Mess” tube allows the massage tip to close by itself after the gel has been applied to the skin. With an emphasis on hygienic application, the unique tube design minimizes gel residue after administration.
In addition, the thin-walled tube’s handle makes it easier for users to apply the gel to their backs and shoulders. The tube head is fitted with a tamper-evident TopStar closure. Prior to receiving the World Star award, the “No Mess” tube had already won the Dow Packaging award, ETMA Tube of the Year and Pharmapack Award in 2018.
Neopac’s trophy case also recently welcomed the addition of an Innovation Award from trade publication Pharma Manufacturing for its SteriDrop tube. Combined with an ophthalmic squeeze dispenser from partner Aptar Pharma, the packaging concept protects preservative-free eyedrops from microbiological contamination before, during and after initial consumer use. SteriDrop can contain volumes up to 30 ml, which can easily cover a three-month supply of daily eye treatment. The system comes with a wide selection of caps and flow rates customized per specific drop formulation.
The SteriDrop mechanical system releases a precisely measured drop when pressure is exerted on the tube, and prevents the liquid from flowing back into the tube, thereby guaranteeing a level of previously unattainable microbiological safety.
Neopac also received a German Packaging Award from the esteemed Deutsches Verpackungsinstitut for Canesten, a cream for treating athlete's foot from Bayer Consumer Health. The applicator is made from a soft thermoplastic elastomer, allowing patients to apply the cream hands-free, an important benefit as athlete’s foot is a highly contagious fungal infection, notes Neopac.
Bayer's requirement was to develop an applicator geometry that would allow effortless treatment of skin areas between the toes. To achieve this, the material of the applicator needed to be flexible and compatible with the filling material. Neopac incorporated a rotating ring on the applicator to prevent leakage and protect the product. On/off marking indicates whether the applicator is open or closed and, thanks to a novel ribbing effect, operation of the rotating ring is convenient for all age groups. The Polyfoil laminate protects the product against light, air and water vapor diffusion and migration.
Polyfoil tube technology was developed by Neopac in 1965 for a customer who was bringing a new toothpaste onto the Swiss market. Existing plastic tubes were not sufficient to protect the new toothpaste formulation, so Neopac created tubing with a laminate that had a sliding inner layer. Overextrusion completely covers the side seam, allowing printing around the entire circumference of the product, and providing stability and restorative force to the packaging, which consumers value.
Hoffmann Neopac produces metal and plastic packaging at locations in Europe, the United States and India.
