Foshan Calmora Bottle Co., Ltd. is an industry-leading OEM/ODM manufacturer specializing in food-grade vacuum flasks, insulated water bottles, travel tumblers, and high-performance food jars. Operating from Foshan, a vital global manufacturing powerhouse in Guangdong, China, we combine state-of-the-art automated production, intensive material research, and lean supply chain mechanics to deliver durable, thermally-efficient products to distribution markets globally.
Founded in 2012, our facilities started as a specialized producer of stainless steel hardware for domestic distribution. Recognizing the global shift toward eco-friendly and thermal-retentive solutions, we transitioned to high-vacuum double-wall manufacturing in 2016. Today, we utilize fully integrated automated robotic lines, 100% vacuum integrity testing, and advanced powder-coating technologies.
Our commitment to material compliance and quality management is validated by our ISO 9001 certification, alongside global standards compliance including FDA, LFGB, and REACH approvals. We serve corporate distributors, outdoor recreation brands, and government procurement agencies across North America, Europe, Central Asia, and the Himalayan corridors.
Engineered for extreme thermal retention, outdoor trekking, and everyday urban lunchbox optimization.
Why Nepal's geographic, demographic, and climatic conditions demand customized thermal drinkware solutions.
From the urban valleys of Kathmandu and Pokhara to trekking base camps like Annapurna and Everest, temperature regulation is critical. Our double-wall insulation prevents rapid heat loss in sub-zero alpine conditions, ensuring cooked meals remain warm for over 12 hours.
Adventure tourism operators and tea houses require robust, drop-proof, and lightweight food containers. The demand for premium quality food flasks among trekkers, mountaineering crews, and expedition planners in Nepal is growing exponentially.
School lunch programs, NGO aid missions, and local businesses in Lalitpur and Bhaktapur are shifting away from single-use plastics to healthy, reusable stainless steel. This presents a high-volume market for customized and bulk-imported OEM vacuum storage.
To sustain food safety standards and thermal integrity, Foshan Calmora Bottle Co., Ltd. manufactures products using Premium SUS 304 (18/8) or optional SUS 316 (18/10) Food-Grade Stainless Steel. These materials provide outstanding corrosion resistance against salt, acidic soups, and continuous washing cycles.
Our thermal retention is powered by a high-grade Vacuum Insulation Layer. During our manufacturing process, air is extracted from the double-walled shell at a temperature of 1000°C using automated high-vacuum furnaces. Additionally, a specialized copper coating is applied to the exterior of the inner wall, reflecting thermal radiation and minimizing heat transfer via conduction and convection.
For seals and plastic components, we prioritize health safety. All lids, handles, and spoons are manufactured using 100% BPA-Free Polypropylene (PP) and food-grade silicone rings, ensuring leakproof operation, even when subjected to rugged high-altitude pressure changes.
Hot Liquid Retention (Initial 95°C)
>70°C after 12 Hours
Cold Liquid Retention (Initial 4°C)
<10°C after 24 Hours
*Tested under standard laboratory environments of 22°C ambient temperature. Performance may vary slightly depending on altitude pressure and lid opening frequency.
From design engineering to customs clearance at Birgunj, Tatopani, or Kolkata ports, we guide you step-by-step.
Our R&D team creates detailed 3D CAD blueprints matching your specifications, including volume capacities (e.g., 400ml, 500ml, 1000ml) and ergonomic lid modifications.
Select surface coatings such as powder finishes, water transfer printings, or customized UV designs. We offer precise laser-engraved or silkscreened brand logos.
Each container is subjected to rigorous vacuum testing. We verify thermal insulation compliance against FDA, LFGB, and customer-specified benchmarks before packaging.
We manage logistics coordinates from Foshan/Shenzhen to Kolkata Port (for overland container transit to Birgunj) or air freight directly into Kathmandu (Tribhuvan International Airport).

Foshan Calmora Bottle Co., Ltd. is committed to forward-looking product design, emphasizing ecological harmony and next-generation functionality.
We are researching plant-based bioplastics for the production of outer lids and carrying handles, reducing the carbon footprint of each unit. Our goal is to achieve 98% recyclability across our entire catalog by 2026.
Our R&D department is designing smart lids integrated with localized LED temperature displays. This allows users to check the internal temperature of stews and soups without opening the container, preserving vacuum integrity.
By thinning the stainless steel walls to 0.08mm through proprietary spinning techniques, we are developing an "Ultra-Lightweight" line. This reduces total product weight by 30% while maintaining double-wall vacuum performance, catering to high-altitude climbers.
Ensuring clear custom processes, product quality certification, and smooth supply line delivery.
Each batch of Calmora vacuum food jars complies with rigorous inspection standards. We supply full testing documentation to our partners in Nepal, including FDA declarations, LFGB compliance certificates, and BSCI social audit reports.
Typically, bulk goods destined for Nepal ship from Shenzhen or Guangzhou ports to Kolkata, India, via maritime transport. From Kolkata, cargo is transported by rail or road to border points like Birgunj or Biratnagar. For high-priority orders, we coordinate direct air freight shipments from Guangzhou to Kathmandu's Tribhuvan International Airport (TIA).
Before leaving the factory, all containers undergo internal pressure, drop, and thermal retention tests. We welcome third-party inspectors, such as SGS or Intertek, appointed by our clients to ensure peace of mind.
