Stackable lidded boxes for household and light-industrial storage. PP and HDPE dominate; UV stabilisation matters for garden and outdoor SKUs.
PP impact copolymer (MFI 8–25) is the workhorse for cold-storage and indoor units. HDPE blow-grade is often used for budget outdoor and garden boxes — typically with carbon-black masterbatch for UV protection. The European market is led by converters like Curver, Keter, and SmartStore who source via long-term direct contracts with Borealis, LyondellBasell, and SABIC. Spot buyers running smaller volumes go through Resinex or Albis for distributor stock.
