CircularBag®
The CircularBag is a large, durable collection bag made from recycled plastic film, available in 200 or 400 litre capacity. It is designed for the efficient collection of plastic foils, sleeves and shrink wrap used in sectors such as horticulture, retail, construction and industry. A practical holder is available to keep the bag open while in use. Filled CircularBags are returned through existing logistics networks, for example via suppliers, wholesalers or exporters, and are then recycled within the Circular Plastics Alliance system into new, high-quality raw materials.
The CircularBag is a simple and effective solution for companies that want to collect and reuse plastic packaging in a responsible and affordable way.
It was originally developed for the floriculture industry, where large volumes of plastic sleeves and foils are used every day, but it has now proven its value across many other sectors, including retail, construction, offices and manufacturing.
Each CircularBag contributes to a fully closed recycling loop. Used foils, sleeves and other plastics are collected and processed into new, high-quality materials, such as flower sleeves made from 100 percent recycled plastic. The CircularBag itself is produced from up to 90 percent recycled material, showing that circularity can be both practical and scalable.
You can order your CircularBags directly from Knapzak, the official distributor within Circular Plastics Alliance.
