450ML Double-Wall Vacuum Stainless Steel Bottle

I. Features (Technical Specifications)

Our 450ML Double-Wall Vacuum Insulated Bottle is engineered for everyday durability and thermal excellence. This model balances portability with capacity, making it a top-tier choice for wholesale buyers.

• Optimal Capacity: The 450ML size is the industry’s “Goldilocks” volume—large enough for a full coffee or soup serving, yet slim enough to fit standard car cup holders.

• Advanced Insulation: Double-wall vacuum insulation technology. (Tested: Keeps liquids hot for 6-8 hours and cold for 10-12 hours).

• Hybrid Material Composition: Food-grade 304 stainless steel inner wall (rust-proof and non-reactive) combined with a 201 stainless steel outer body (economical and impact-resistant).

• Compact Dimensions: 6.8 cm (diameter) x 7.2 cm (base) x 26.1 cm (height). This slender profile is specifically engineered for the 450ML volume without excessive bulk.

• Lightweight Build: Only 265 grams net weight. This featherlight construction makes the 450ML bottle easy to carry in a backpack or handbag.

• Ready Inventory: Multiple existing designs available in stock. For standard 450ML models, samples are ready within 48 hours.

• Customization Ready: Supports surface treatment (powder coating, sandblasting), color matching (Pantone/RAL), logo printing (screen print, laser engraving, pad print), and custom packaging.

II. Benefits (Why Choose This 450ML Bottle)

The 450ML capacity is not just a number; it is a strategic advantage for both end-users and distributors.

For the End-User:

• Perfect Hydration Portion: The 450ML volume holds exactly one large coffee (Starbucks Grande) or one bowl of soup. It is neither too heavy nor too small, reducing the need for refills during a morning commute.

• Temperature Retention: Because the 450ML chamber is narrow (6.8cm), heat loss is minimized compared to wide-mouth bottles. Your morning tea stays steaming hot until lunch.

• Leak-Proof Confidence: Every 450ML unit undergoes a 100% water seal test before packing. No spills in your briefcase.

• Safe Materials: The inner 304 steel ensures no metallic taste. All 450ML mugs pass LFGB, FDA, and EU stringent migration tests.

For the Distributor/Retailer:

• Reduced Logistics Costs: At 265g per unit, the 450ML bottle allows for lower shipping weight (approx. 13.5kg per 50 units) compared to 500ml+ competitors.

• High Conversion Rate: The 450ML price point is the “sweet spot” for promotional giveaways and retail shelves—affordable enough for mass purchase, premium enough for branding.

• Lower MOQ Risk: With an MOQ of 3,000 units for the 450ML line, you can launch a private label without overstocking.

V. Frequently Asked Questions (FAQ)

Q1: What is the exact net weight of the 450ML bottle? Is it really lightweight?
*A: Yes. The net weight is exactly 265 grams. Our 450ML bottle is 15% lighter than standard 500ml thermoses because of the optimized wall thickness (0.4mm inner + 0.3mm outer). This makes it ideal for school lunch boxes and hiking bags.*

Q2: The lead time says 40 days, but you mentioned 15 days. Which is correct?
A: Both are correct.

• If you select a 450ML model from our “Existing Stock Designs” (no new color or mold), the lead time is 15 days.

• If you require custom Pantone colors or new printing plates for the 450ML body, lead time is 40 days (includes 10 days for dry paint curing).

Q3: Is the 304 stainless steel on the inside guaranteed? How to test?
A: Absolutely. We provide an Material Composition Report for every batch of 450ML mugs. You can use a Molybdenum test kit (304 contains Mo, 201 does not). The inner wall of the 450ML model is clearly marked “304” via laser engraving per LFGB standards.

Q4: What certifications do you have for the 450ML mug?
*A: The 450ML Double-Wall Mug has passed:*

• *LFGB (German food safety – Section 30 & 31)*

• *FDA (US standard – 21 CFR 175.300)*

• *EU (European regulation 10/2011 for plastics in lids)*
  We issue the test report for every 450ML order upon request.

Q5: Does the 6.8cm diameter fit standard car cup holders?
A: Yes. Most car cup holders range from 6.5cm to 7.2cm. The 450ML mug’s 6.8cm base diameter fits 98% of Toyota, Honda, BMW, and Ford vehicles. The 26.1cm height sits just below the dashboard armrest.

Q6: What is your MOQ? Can I mix colors to reach 3000?
*A: The strict MOQ for custom production is 3,000 units per design/shape. However, for the 450ML “Stock Ready” program, you can mix up to 3 colors (e.g., 1,000 Black + 1,000 White + 1,000 Blue) to reach the 3,000 total MOQ.*

Q7: The outer material is 201 stainless steel. Will it rust?
*A: 201 stainless steel is corrosion-resistant for dry/daily use. The outer 450ML body has a protective powder coating. However, we do not recommend leaving the wet 450ML bottle in saltwater for 24 hours. For high-humidity environments (beach clubs), we suggest upgrading the outer material to 304 (additional $0.30/unit).*

Q8: Can I get a sample before placing the 3000 MOQ order?
*A: Yes. For existing 450ML stock designs, samples cost $15 (including shipping). This is refundable upon placing the formal 3,000-unit order.*

Q9: What printing methods do you use for the 450ML logo?
A: For the curved 450ML body (26.1cm height), we recommend:

• Silkscreen (Cheapest, 2 colors max)

• Laser (Best for metallic finish, no minimum color)

• UV Transfer (Photographic quality for complex 450ML brand logos)

Q10: How do I ensure the LFGB compliance for my custom packaging?
*A: We only use LFGB-certified inks for printing on the 450ML body. For packaging, we avoid recycled cardboard with heavy metals. We provide a “Declaration of Conformity” for the 450ML product and its packaging upon shipment.
