Industrial polymer packaging — jerrycans, drums, and IBC containers made of HDPE for the storage and transportation of liquid chemical products, fuels and lubricants, and food liquids. HDPE provides chemical resistance to acids, alkalis, and solvents. Jerrycans 5–60 liters — for dispensing household chemicals, fuels and lubricants, agrochemicals. Drums 120–227 liters — for chemical reagents, oils. IBC containers 1000 liters (Eurocube) — steel frame + HDPE inner container on a metal pallet. Production: extrusion blow molding. UN certification for the transport of dangerous goods. UN certification: packaging for dangerous goods undergoes tests (drop, stacking, hydraulic, leakproofness) and receives UN marking with a packaging group (I/II/III). Without UN marking, the transport of dangerous goods by road and sea is prohibited (ADR/IMDG). Production: extrusion blow molding on automatic lines. Wall: HDPE with UV stabilizer (for outdoor storage). Documentation: UN certificate, quality certificate.
