The majority of flip-top and screw caps for tubes are currently made from polypropylene (PP) because they form a good seal on the polyethylene tube shoulder and provide an attractive surface. However, combining different types of plastic in packaging has a recyclability disadvantage, as it means that sorting by type is not possible. We have managed to find HDPE materials which are easily workable and of an optically high quality. They provide a perfect seal for PE tubes. Mono-material packaging makes things much easier for you and the consumer: The packaging indicates the tube is recyclable in the PE stream.
Why is this so important?
Mono-material plastic tubes which can be sorted by type and tube bodies and caps made from PE materials are key factors in guaranteeing a more sustainable recycling process. Recyclable mono-material tubes contribute significantly to an effective circular economy, which results in less waste.
In addition to the HDPE Flip-top caps with diameters of between 30 and 50 mm, we also offer a comprehensive portfolio of PE screw caps suitable for pharmaceutical and food products. Some of these screw caps are manufactured at our Swiss site and are available with diameters of between 10 and 40 mm. Our development department has thoroughly checked that the new HDPE caps are of the highest quality. The HDPE caps are functionally identical and optically similar to PP caps. They can be combined appropriately with our PE and EcoDesign tubes.
