600ML Double Wall Vacuum Thermal Food Jar
1. Product Features
Our 600ML double wall vacuum thermal flask is a practical and durable daily-use insulated container designed for global consumer markets, integrating premium material configuration, portable structural design, stable vacuum insulation technology and multi-scene applicability. Every detail of this 600ML thermal flask is optimized for mass sales and customized wholesale, making it one of our most popular stock insulated products with multiple mature styles available for immediate selection. In terms of material composition, the flask adopts a dual-layer stainless steel structure with inner 316 stainless steel and outer 201 stainless steel, a classic and cost-effective material combination that balances food safety, structural firmness and market affordability. The inner 316 stainless steel is a high-grade food-contact material with excellent corrosion resistance, oxidation resistance and acid and alkali tolerance, which can safely hold various foods and beverages including porridge, soup, coffee, tea, fruit drinks and carbonated drinks without producing harmful substances or metallic odors. The outer 201 stainless steel ensures solid overall structure, scratch resistance and drop resistance, effectively protecting the inner vacuum layer and extending the service life of the entire flask.
In terms of structural performance, the core double-wall vacuum insulation design is the biggest highlight of the 600ML thermal flask. The vacuum gap between the inner and outer walls greatly blocks heat conduction, convection and radiation, realizing long-term heat and cold preservation, meeting the daily heat preservation and fresh-keeping needs of families, offices, outdoor activities and travel scenarios. The product features a compact and standardized size of 11.8*11.8*7.3cm and a lightweight body of only 251g, which breaks the bulky disadvantage of traditional large-capacity thermal flasks. The moderate 600ML capacity perfectly fits individual daily use and small-family meal preparation, avoiding excess capacity waste while meeting the demand for long-time fresh food storage. In addition, this 600ML thermal flask has passed authoritative international food safety tests, including LFGB, FDA and EU standard certification. All raw materials and production processes comply with European and American food contact safety regulations, with zero harmful substance precipitation, BPA-free and environmentally friendly, fully adapting to mainstream global consumer safety standards. Meanwhile, we support diversified surface treatments, color customization, pattern printing and personalized packaging modification, and multiple finished styles are in sufficient stock to support rapid delivery for bulk orders.
2. Product Benefits
The 600ML double wall vacuum thermal flask brings substantial practical value and market competitive advantages to end consumers and wholesale customers, covering user experience, safety guarantee, cost performance and business flexibility. For end users, the most intuitive benefit is reliable temperature retention and food fresh-keeping performance. The professional vacuum insulation technology can keep hot food and drinks warm for a long time and maintain low-temperature freshness of cold beverages, solving the pain points of fast temperature loss of ordinary containers and inability to store fresh food for a long time. Whether users need to carry warm porridge and soup for breakfast, store hot coffee and tea for office work, or prepare cold drinks and fresh fruits for outdoor hiking and travel, this 600ML thermal flask can provide stable and lasting insulation effect, improving daily diet quality and convenience.
The safe and healthy material configuration is another core benefit of the product. The food-grade 316 stainless steel inner liner is far superior to ordinary 304 stainless steel in anti-rust and anti-corrosion performance, and it can resist erosion of acidic and alkaline foods, effectively avoiding bacterial growth and residue odor. It ensures long-term clean and safe use, which is very suitable for children, office workers, outdoor enthusiasts and family daily use. The lightweight 251g body and portable 11.8*11.8*7.3cm size make the 600ML thermal flask easy to carry and store, not occupying extra space in backpacks, handbags or kitchen cabinets, realizing truly portable insulated storage. For wholesale and corporate customers, the product’s biggest advantage is flexible supply and high cost performance. With multiple finished styles in stock, customers can choose ready-made products for quick replenishment without long production cycles. The reasonable MOQ of 3000 pieces lowers the threshold of bulk procurement, suitable for supermarket retail, cross-border e-commerce, gift customization and brand distribution businesses.
Moreover, the customizable performance greatly improves product market adaptability. Customers can adjust surface texture, body color, logo printing and outer packaging according to local market preferences and brand positioning, creating exclusive customized products to enhance brand competitiveness. The full compliance with LFGB, FDA and EU certifications also eliminates market access barriers, allowing the 600ML thermal flask to be smoothly sold in European, American and other mainstream international markets, reducing customer’s market inspection and sales risks. Compared with similar products, this thermal flask balances quality, price and practicability, with stable quality, diverse styles and flexible customization, bringing higher profit margins and stable sales volume for cooperative customers.

4. Order Process
The ordering process of our 600ML double wall vacuum thermal flask is standardized, efficient and transparent, covering consultation, confirmation, production, inspection and delivery, which facilitates customers to arrange procurement plans efficiently. The first step is demand consultation and product selection. Customers can put forward detailed procurement demands, including purchase quantity, selected stock style, customized requirements (color, printing, packaging, etc.) and certification needs. Our professional sales team will provide targeted product recommendations, quote accurate unit price and total cost, and clarify the corresponding delivery cycle according to customer demands. The second step is sample confirmation and order signing. For customized orders, we will produce pre-production samples according to the confirmed customization scheme. After customers check and confirm the sample quality, appearance and details, both parties will sign a formal sales contract to clarify product parameters, customization standards, MOQ, delivery time, payment terms and after-sales clauses to ensure the legitimate rights and interests of both parties.
The third step is deposit payment and formal production. After the contract takes effect, customers pay the agreed deposit, and we will immediately arrange production scheduling. For stock style orders with simple customization, we start rapid customized processing and finish production within 15 days; for mass customized orders and new ODM development orders, we follow the 40-day leading time schedule to carry out batch production strictly in accordance with quality standards. The fourth step is quality inspection and finished product sorting. After the completion of batch production, our quality inspection team will conduct full inspection on all 600ML thermal flasks, including appearance inspection (no scratches, no deformation, clear printing), structural inspection (tight sealing, stable structure) and performance inspection (normal vacuum insulation function). Unqualified products will be eliminated uniformly to ensure 100% qualified rate of delivered goods.
The fifth step is balance payment and shipment arrangement. After customers confirm the inspection report and finished product pictures, they pay the balance payment, and we will arrange professional packaging and container loading immediately. We adopt tight and stable loading methods with auxiliary reinforcement measures such as heavy-duty straps and air bags to prevent product shifting, collision and damage during sea and land transportation. The last step is after-sales follow-up. We will provide logistics tracking information in real time, and follow up the cargo arrival status after shipment. If customers have any product quality and after-sales problems after receiving the goods, our team will provide professional solutions within 24 hours.
