Food-safe HDPE construction and airtight seals give confidence when storing drinking water, cooking ingredients or cleaning fluids. Are UN-certified canisters overkill for household use, or sensible protection when moving hazardous liquids?
⚡ At a Glance
- • Material Durability: HDPE construction resists chemicals, odours and temperature-related deformation
- • Best for: Homeowners, small businesses and hobbyists needing safe liquid storage and transport
- • Not ideal for: Users who need built-in taps or hands-free dispensing solutions
Two 2.5-litre HDPE canisters come with black safety caps and tamper-evidence rings. DIN 45 filling opening, UN 3H1/Y1.9 certification and airtight seals make them suitable for foodstuffs and approved transport of dangerous goods.
Certified Transport – With UN 3H1/Y1.9 approval
UN 3H1/Y1.9 classification confirms construction and testing standards required for transporting certain hazardous liquids. Certification covers material strength, sealing and safe handling under transport conditions.
Approved for moving classified liquids, offering peace of mind when packing or shipping chemical products. Useful for anyone who occasionally needs to transport hazardous fluids legally and safely.
Food-Ready Storage – Thanks to food-safe HDPE construction
High-density polyethylene is food-grade, chemically inert and resists leaching, while odour- and taste-neutral properties prevent flavour transfer. Material tolerates a wide temperature range without chemical breakdown.
Safe for storing drinking water, edible oils or ingredients without altering taste or smell. Handy for camping, emergency water storage or kitchen bulk storage.
Secure Closure – With DIN 45 cap and tamper-evidence ring
DIN 45 filling opening (Ø 34.5 mm) pairs with a black safety cap and tamper-evidence ring to create an airtight, watertight seal. Seals are designed to be easily closed and visibly indicate prior opening.
Leakproof transport and clear evidence if seals have been broken during handling. Practical when sharing containers between households or storing items long-term.
