Direct Factory Wholesale Offerings Optimized for B2B Retailers, Amazon Sellers, and Corporate Buyers
Strategic Analysis of Materials, Thermal Efficiency Standards, and Sustainable B2B Packaging Architectures
Global consumer markets have shifted irrevocably toward food-grade 18/8 (304) and 316 medical-grade stainless steel. Standard plastic and low-grade aluminum drinkware are rapidly being phased out due to strict environmental directives (such as the EU Single-Use Plastics Directive) and consumer demand for BPA-free, toxin-safe daily hydrators.
Modern vacuum insulation engineering utilizes high-efficiency getter materials and automated continuous vacuum firing kilns. Eliminating air between internal and external steel walls drops thermal conductivity to near zero, maintaining hot beverages above 65°C for 12+ hours and cold beverages below 8°C for up to 36 hours.
As cross-border Amazon FBA and global retail distribution scale, custom wholesale mug boxes must meet stringent ISTA-1A/3A drop-test criteria. Precision-cut corrugated inserts, internal molded pulp trays, and customized high-density outer master cartons drastically cut transit damage rates to under 0.05%.

Why Leading Brands, Importers, and Amazon Aggregators Partner with Wuyi Dongyi
Our facility leverages high-speed hydraulic expansion lines and multi-station necking machines to craft seamless stainless steel shapes. This reduces metal fatigue and ensures uniform wall thickness across 40oz quencher tumblers and 20oz skinny designs.
Unlike standard mechanical buffing, our automated electropolishing passivates the interior SS304 wall, creating a smooth layer of chromium oxide. This prevents residual flavor retention, rust formation, and chemical leaching under acidic conditions.
We integrate product manufacturing with custom gift box packaging. From corrugated structural design to CMYK offset printing, foil stamping, and anti-counterfeiting QR integration, we provide shelf-ready solutions directly out of the container.
Wuyi Dongyi Dailysupplies Co., Ltd is located in the beautiful Wuyi county, Zhejiang Province, China. It is specialized in production, research and development of kinds of food grade stainless steel tumblers, mugs, bottles, cups, jugs and containers, etc. Both double-walled vacuum insulation construction and single wall construction are included.
We have advanced production machines and testing equipment, a strict quality control system, and a professional team of research & development with years of experience in this field. From original engineering designs to final mug box assembly, our operations conform strictly to international ISO9001 management standards.
From our founding, our company has obeyed these core principles: Quality First, Service First. We have established long-term business relationships with clients across North America, Europe, South America, the Middle East, and Southeast Asia. OEM and ODM orders are welcomed.
A Seamless 6-Step Engineering and Delivery Pipeline Designed for High-Volume OEM/ODM Clients
Our company adheres continuously to these tenets: Quality First, Service First. We have cultivated deep partnerships with buyers across North America, Western Europe, South America, the Middle East, and Southeast Asia.
Our product lines comply fully with FDA 21 CFR 175.300 standards, European Regulation (EC) No 1935/2004, LFGB food-contact mandates, and California Proposition 65 toxicity constraints. Every batch is manufactured under heavy QA inspection to guarantee absolute heavy-metal-free (Lead, Cadmium, Phthalate-free) safety.
With customized surface coating colors, creative pattern & logo execution, and innovative functional lids, our drinkware and box packaging offer exceptional shelf appeal and retail sales velocity.
Pioneering Next-Generation Insulation Technologies, Smart Thermal Monitoring, and Zero-Waste Packaging Architecture
Engineered via precision rotary swaging, our next-generation inner steel walls are thinned to 0.4mm without sacrificing structural compression resistance. This decreases total product weight by 18%, significantly lowering international freight costs per unit.
Integrating real-time digital LED temperature displays directly into BPA-free lids without compromising vacuum seal integrity. Smart sensor modules offer precise beverage temperature readings for high-end promotional and corporate luxury segments.
Transitioning from traditional plastic polybags to water-soluble plant-starch bags and 100% post-consumer recycled (PCR) unbleached kraft cardboard mug boxes, aligning fully with corporate ESG mandate requirements.
