Explore our flagship OEM/ODM stainless steel straw cups, tumblers, and thermal flasks engineered for precision temperature control, leak-proof performance, and premium retail presentation.
The global reusable drinkware and insulated straw cup industry is experiencing a seismic shift driven by evolving consumer lifestyles, stringent environmental mandates against single-use plastics, and rapid innovation in material science. As brand owners, Amazon FBA sellers, and global B2B distributors seek high-margin OEM/ODM manufacturing partners, selecting an experienced ODM Straw Cup supplier has become a strategic imperative for sustainable brand growth.
The transition from traditional acrylic or single-wall plastic straw cups to premium 18/8 (Food Grade 304) Stainless Steel double-wall vacuum insulated straw tumblers reflects consumer demand for prolonged thermal performance—keeping drinks ice-cold for up to 34 hours or piping hot for over 12 hours. Modern buyers demand multi-functional straw lids, ergonomic handles, cupholder-compatible bases (75mm diameter standard), and sweat-proof exterior coatings such as powder spraying, sublimation, and electro-plated metallic finishes.
| Material Benchmark | Food Grade 304 Stainless Steel (18/8) | 201 Stainless Steel (Lower Grade) | Tritan / BPA-Free Plastic |
|---|---|---|---|
| Corrosion Resistance | Exceptional (High Chromium & Nickel Content) | Moderate (Prone to rust over long exposure) | High Chemical Inertness |
| Thermal Insulation | Ultra-High Double-Wall Vacuum Core | Medium Double-Wall Vacuum Core | Single/Double Wall Air Gap Only |
| Durability & Impact | Indestructible, Shatterproof Structural Frame | Moderate Structural Rigidity | Impact Resistant, But Prone to Scratching |
| Regulatory Compliance | FDA, LFGB, EU Food Contact Approved | Restricted for Premium European Imports | BPA-Free Compliant |
Wuyi Dongyi Dailysupplies Co., Ltd is strategically located in Wuyi County, Zhejiang Province, China—the global epicenter of stainless steel vacuum container production. Specialized in the research, engineering design, and mass manufacturing of food-grade stainless steel tumblers, straw cups, mugs, sports bottles, and insulated jugs, our facility operates both double-walled vacuum insulation lines and precision single-wall processing setups.
Operating under the unwavering corporate tenets of "Quality First, Service First", Dongyi integrates state-of-the-art automated welding machines, high-vacuum pumping extraction arrays, strict multi-stage quality control protocols, and an elite in-house R&D engineering team.
Full-service rapid prototyping, 3D CAD modeling, custom mold building, and bespoke functional lid designs tailored to brand specifications.
Certified premium 18/8 (SUS304) inner liners ensuring toxin-free, BPA-free, lead-free vacuum seals that preserve taste purity.
Industrial powder coating, 3D digital UV printing, water transfer printing, laser engraving, and custom gradient finishes.
What sets Wuyi Dongyi apart in the global supply chain is our commitment to thermal insulation engineering precision. Standard straw cups often suffer from thermal leakage through uninsulated lid ports or inadequate vacuum evacuation. Our ODM engineering team resolves these issues through a multi-layer design approach:
Our multi-drinking lid options (specifically designed for 40oz Quencher tumblers and 30oz Hydra Quencher models) feature a rotating cover with three positions: a straw opening designed to resist splashes with a seal that holds the reusable straw in place, a drink opening, and a full-cover top for added leak resistance.
Understanding localized consumer habits and regulatory standards is essential for successful international distribution. Wuyi Dongyi supports OEM/ODM brand localized positioning across key geographic segments:
Demand centers on massive capacity (40oz and 30oz Hydra Quencher tumblers) with heavy-duty handles and tapered bases designed to fit standard automotive cup holders. Custom colors follow seasonal fashion trends, requiring powder coating durability and Prop 65 compliance.
Emphasis is placed on strict eco-friendly compliance (LFGB food contact certification, REACH chemical safety) and sleek, minimalist designs such as 20oz Skinny Tumblers and cone-shaped cola bottles with eco-conscious silicone straws.
Regional preferences include specialized cultural drinkware such as the double-wall insulated 8oz Yerba Mate Gourd cup, alongside high-durability sports flasks capable of withstanding rugged outdoor conditions.
Global Export Network & Distribution Reach
Our streamlined 6-step manufacturing workflow guarantees complete transparency, fast lead times, and flawless quality execution from initial design inquiry to final delivery.
As a forward-looking OEM/ODM manufacturer, Wuyi Dongyi is pioneering several advanced drinkware manufacturing technologies that will shape the market over the next decade:
Transitioning to Post-Consumer Recycled (PCR) stainless steel allows global brands to reduce carbon footprints by up to 40% without compromising structural integrity or food safety standards.
Integrating food-grade silver-ion antimicrobial agents directly into silicone straw matrices to inhibit 99.9% of bacterial growth in humid environments.
Utilizing precision hydroforming to reduce stainless steel wall thickness from 0.4mm to 0.3mm while maintaining structural strength, reducing total product weight by 15%.

OEM (Original Equipment Manufacturing): We manufacture straw cups strictly based on your existing design blueprints, CAD models, and specified branding requirements.
ODM (Original Design Manufacturing): We provide fully realized, ready-to-brand product designs—including custom lid mechanisms, body contours, and ergonomic handles—allowing you to launch products quickly with lower tooling investment.
We primarily use premium Food Grade 18/8 (SUS304) Stainless Steel for inner liners to guarantee complete food safety, corrosion resistance, and metallic-taste-free hydration. Outer shells can be customized in 304 or 201 SS depending on market budget requirements.
Our 40oz and 30oz vacuum insulated tumblers maintain cold temperatures below 8°C (46.4°F) for up to 24 to 34 hours with ice, and keep hot beverages warm above 60°C (140°F) for over 12 hours under standardized thermal chamber testing.
Yes. All plastic and silicone components (lids, straws, internal seals) are constructed from 100% BPA-free, non-toxic food-grade AS/Tritan and silicone. Our multi-function press-in and screw-on lids feature precision silicone gaskets for maximum splash and spill protection.
Standard MOQs start at 1,000 pcs per color/style for custom powder-coated items. Pre-production sample lead time is typically 7–10 days, while mass production fulfillment averages 25–35 days upon sample approval and deposit confirmation.
