The Double Lid Portable Vacuum Flask is a 0.5 L insulated container designed for hot beverage transport. After six hours the internal temperature remains at least 78 °C, ensuring prolonged heat. The body is moulded from polypropylene (PP) plastic, a material widely used for its chemical resistance and lightweight properties. Both lid and stopper are also PP, with the lid engineered to function as a drinking cup.
The PP construction allows custom colours and patterns, and the supplier can apply branding or bespoke designs on request. The bottom incorporates a skid‑resistant PP ring and is easily detachable for cleaning, a common feature in portable vacuum flasks. The glass refill component employs Japanese‑technology glass, delivering the high thermal retention cited in the specifications. Typical double‑wall vacuum insulation in similar flasks uses a wall thickness of around 2 mm, giving comparable heat‑holding performance.
This product is suited for outdoor enthusiasts, office workers and hospitality services that require reliable hot drink delivery. Buyers can request OEM production and colour customisation, with the supplier indicating acceptance of such orders. As pricing and minimum order quantities are not disclosed, prospective importers should ask the supplier for MOQ and unit cost. Shipping arrangements, incoterms and payment schedules are negotiated directly with the company.

Importers should first confirm the flask’s capacity, heat‑retention performance and material certifications, and request a sample to verify the custom colour finish and lid functionality. Ask the supplier for details on minimum order quantities, packaging options and any available test reports for thermal performance.
Shipping from Hanoi usually proceeds via sea freight from Hai Phong or Da Nang ports, or air freight for smaller volumes. Discuss incoterms such as FOB Hai Phong or CIF your destination port, and agree on payment terms - many Vietnamese manufacturers accept T/T after a pro‑forma invoice. Lead‑time is not listed, so obtain an estimated production schedule once the order specifications are finalised.
Quality checks should include verification of the vacuum seal integrity, measurement of heat retention after six hours, and inspection of the PP components for colour consistency and surface finish. Request a test report showing the ≥78 °C retention claim and consider a third‑party inspection before loading to ensure the product meets the agreed specifications.
