Neopac’s Lightweight Tube Cuts Virgin Plastic By 30%

Switzerland-based packaging supplier Hoffmann Neopac has made a materials-science breakthrough, developing a tube for cosmetics and personal-care applications that reduces virgin material use by 30% without sacrificing product protection, aesthetics, or haptics. Called the Eco-Stripped Tube, the package features significantly reduced sleeve-wall thickness plus material reduction in the tube’s shoulder and cap. The sleeve wall of the new tube is 0.35 mm thick vs. 0.50 mm for a conventional tube. The Eco-Stripped sleeve can be made from mono-polyethylene (PE), PE/ethylene vinyl alcohol (PE/EVOH), with 64% post-consumer recycled (PCR) content, or with bio-based content. The shoulder can be made from high-density PE (HDPE) or recycled HDPE (rHDPE), and the flip-top cap is polypropylene (PP). A lower-profile shoulder and cap characterize the new design. For size D50, the new tube sits 9.4 mm lower and is 3.75 g lighter than conventional designs. Diameters of 30 mm, 40 mm, and 50 mm, with volumes ranging from 40 to 300 ml, are available.
