Explore our high-performance, food-grade plastic containers, lunch boxes, and hydration solutions designed for international market compliance.
A technical overview of material safety, injection molding technologies, and supply chain strategies for international procurement executives.
Modern global markets demand absolute purity in food-contact materials. Advanced OEM operations utilize virgin Polypropylene (PP-5), Tritan, and 304/316 Stainless Steel that strictly satisfy FDA 21 CFR 177.1520 and EU Regulation No. 10/2011 standards. Every product batch undergoes rigorous testing for phthalates, heavy metals, and Bisphenol A (BPA) migration.
Creating leak-proof multi-compartment lunch boxes requires ultra-precise mold fabrication. Utilizing multi-cavity hot runner injection technology, production tolerances are held within ±0.05mm. Dual-injection co-molding allows integrated TPE/silicone gaskets that ensure air-tight, leak-proof performance without secondary manual insertion.
From microwavable single-wall containers to double-wall vacuum-insulated stainless steel bentos, structural thermal modeling optimizes temperature retention. High-density PU insulation layers or vacuum jackets maintain hot meal temperatures above 60°C for up to 6 hours while maintaining ambient exterior temperatures for user safety.
Huangyan Dadi Plastic Product Factory is located in the prestigious "International Plastic Kingdom" of Huangyan District, Taizhou City, in eastern Zhejiang Province. Our facility is strategically positioned just 8 kilometers from Jiaojiang Port, 160 kilometers from Ningbo Port (one of the world's largest container hubs), and 18 kilometers from our local Airport. This seamless multimodal transport access guarantees rapid dispatch and rapid delivery of all international enterprise bulk orders.
Manufacturing a wide range of plastic household products, our main core catalog includes fruit peeling devices, pots, children's water cups, microwavable lunch containers, and specialized kitchen utensils. Operating under the corporate ethos of "Quality First, Customers First" and guided by the management philosophy of "Develop with Science and Technology", we offer end-to-end OEM/ODM partnership solutions to global buyers.
From initial CAD modeling to high-volume injection molding, we support global brand customization with turnkey agility.
Our in-house design team facilitates full branding integration. We offer High-Definition In-Mold Labeling (IML), Silk Screen Printing, Heat Transfer, and custom surface texturing (matte, glossy, soft-touch coatings) tailored to regional consumer aesthetics.
Accelerate your time-to-market. Utilizing 3D SLA printing and rapid aluminum tooling, we provide functional physical prototypes within 5-7 business days for structural, drop-test, and spill-proof verification prior to mass steel tool cutting.
We provide full documentation suites for global compliance. Our products are accompanied by material test reports (SGS, TUV, BV), ISO9001 quality audit certification, and compliance certificates for regional entry across North America, Europe, and Asia-Pacific.
With 24 years of manufacturing heritage, we combine advanced production tech with 24/7 client support.
Decades of specialized injection molding expertise ensuring defect-free production and stable material sourcing.
Dedicated technical engineering team and modern high-speed injection machines for high output and consistency.
Full-process quality checks from raw plastic pellet inspection to drop testing and leak testing before packing.
Round-the-clock sales and technical support to assist overseas procurement teams across all time zones.
Adapting plasticware manufacturing to meet sustainability mandates and diverse consumer lifestyles worldwide.
Driven by single-use plastic bans across the EU and North America, our OEM development has expanded into bio-composite materials like wheat straw PP, bamboo fiber blends, and Post-Consumer Recycled (PCR) resins. These materials reduce fossil fuel reliance while maintaining 100% food safety and thermal stability during microwave use.
Educational institutions require durable, easy-to-open, non-toxic containers. Our children's lunch box series features child-friendly latch systems, drop-resistant elastomer bumpers, and modular compartments that support balanced nutritional portions while preventing liquid cross-contamination.
Urban working professionals prioritize sleek, minimalistic aesthetic design alongside microwave suitability and leak-proof reliability. Our adult bento product lines integrate slim profile silhouettes that slide effortlessly into work bags, combined with steam-vent valves for safe microwave reheating.
