Explore our primary range of food-grade certified clamshells, custom window boxes, and high-clarity clear-lid dessert packaging built for automated lines and retail displays.
In the modern commercial baking industry, packaging is no longer merely a protective vessel—it is a critical extension of cold-chain logistics, shelf-life management, and automated manufacturing efficiency. As global bakery chains and supermarket delis scale up operations, the demand for ODM (Original Design Manufacturing) Cake Clamshell Packaging has transitioned from off-the-shelf commoditized boxes to high-precision thermoformed solutions.
Enterprise packaging procurement mandates strict parameters: crystal-clear anti-fog visibility under refrigerated displays, mechanical hinge longevity, secure dual-button perimeter snap locks, and optimized denesting geometry for high-speed automated packaging machinery. Our 10,000 m² advanced manufacturing facility delivers custom-tailored polymer packaging engineered to solve real-world operational bottlenecks.
Selecting the exact resin formulation and wall thickness profile dictates structural performance under refrigeration, transport vibration, and handling. We utilize virgin and recycled food-grade resins precision-extruded into multi-layer sheet profiles.
The industry benchmark for premium cake clamshells. Delivers ultra-high optical transparency, superior impact resistance at chilled temperatures (0°C to 5°C), and 100% kerbside recyclability. Available with up to 100% Post-Consumer Recycled (PCR) content.
Engineered for applications requiring microwave reheatability, hot-fill baked goods (up to 120°C), or deep-freeze resilience (-20°C). Provides outstanding flexural fatigue resistance for living hinges during repeated open/close cycles.
Derived from renewable plant starches (cornstarch), fully bio-based and industrially compostable under EN 13432 / ASTM D6400 standards. Ideal for eco-conscious organic bakery brands seeking zero-petroleum packaging footprints.

Located in Anbu Town, Chaozhou—the premier food-grade packaging hub of Southern China—Chaozhou Weiting Packaging Products Co., Ltd. integrates raw material sheet extrusion, high-speed multi-station thermoforming, precision CNC aluminum tooling, and automated inline packing under one roof.
Our 5-axis CNC machining centers enable custom CAD-to-mold prototype turnaround in as fast as 3 to 5 business days, reducing upfront NRE (Non-Recurring Engineering) tooling costs by up to 60% compared to Western tooling houses.
Deploying high-efficiency automated thermoforming presses (including Mengxing and Zhongbo units) with robotic stacking, generating an annual throughput capacity exceeding 150 million clamshell units.
Our structural engineers design specialized stacking shoulders and nesting ribs that allow up to 35% more units per shipping carton, drastically slashing international ocean freight costs per unit for overseas importers.
Navigating food-contact regulations across different jurisdictions requires absolute material traceability and rigorous testing protocols. We supply full regulatory documentation packages with every batch shipment.
Full compliance with United States Food and Drug Administration specifications for polyethylene phthalate polymers used in direct contact with food, including overall migration limit (OML) testing under room temperature and refrigeration conditions.
Certified under European Union plastics food contact laws, heavy metals restriction (RoHS Directive), and REACH SVHC (Substances of Very High Concern) screening, enabling seamless entry into all EU member states.
Support for custom hot-foil stamping, multi-color offset printed cardboard base sleeves, barcode/QR typesetting, localized nutritional labeling, and multi-language consumer warnings directly applied at the factory.
For large-scale bakeries running high-speed filling lines, packaging sticking or misaligned closure snaps cause costly machine downtime. Our engineering team designs specific mechanical enhancements into every custom clamshell mold.
Micro-engineered corner lugs prevent vacuum lock between stacked clamshells. Automatic denesting arms can pick and drop containers onto conveyor lines without double-feeding or jamming.
Precision-molded perimeter button locks provide an audible 'click' confirmation upon manual or automated closure, guaranteeing a spill-proof, tamper-resistant seal during transit.
Vertical load distribution channels built into the corners transfer weight away from delicate cake decorations, supporting 3 to 4-high pallet stacking in distribution centers.
Market intelligence reveals three massive structural shifts driving global procurement strategies through 2030.
Global retail chains are phasing out single-use virgin plastics in favor of Post-Consumer Recycled rPET containing up to 100% bottle-flake content. Closed-loop recycling certifications are becoming mandatory for Tier-1 suppliers.
Traditional temporary anti-fog sprays are being replaced by permanent inline surface treatments that prevent condensation misting even when warm cakes are placed directly into refrigerated display cases.
With the rise of third-party food delivery platforms (UberEats, DoorDash), integrated tear-strip tamper-evident clamshell hinges are experiencing rapid adoption to guarantee food safety upon doorstep delivery.
Different commercial environments present unique packaging requirements. Our ODM capability matches structural design to exact operational environments.
Ultra-clear PET dome lids with anti-mist coating maximize impulse purchasing in self-serve deli refrigerated cabinets while holding internal moisture levels steady.
Uniform denesting margins and standardized outer dimensions optimized for robotic pick-and-place filling, automated labeling, and shrink-band machinery.
Custom-printed paperboard bases combined with crystal dome covers offer a luxury gift presentation with gold/silver hot-foil brand accents.
Heavy-duty gauge PET containers with reinforced perimeter locks designed to withstand multi-stop courier transit and thermal ice-pack pressure.
Explore additional specialty bakery bases, multi-grid cupcake containers, seasonal treat boxes, and cake drums engineered for commercial applications.
Direct technical answers from our engineering desk regarding custom mold tooling, minimum orders, food contact testing, and shipping workflows.
For existing factory stock mold structures with customized printed paper sleeves or branded bases, our standard MOQ starts at 3,000 to 5,000 units per SKU. For fully custom thermoforming aluminum tooling (brand-new shape, custom height, or proprietary locking geometry), the production MOQ is 10,000 units per SKU. Steel/aluminum mold fees range from $800 to $2,500 depending on cavity count, and mold costs are fully refunded once cumulative order volumes reach 100,000 units.
Every raw resin batch (PET, rPET, PP) is delivered with raw material Certificates of Analysis (COA). Our finished containers undergo batch-level overall migration, heavy metal content, and sensory flavor-transfer testing certified by third-party testing agencies (such as SGS or TÜV) to comply with US FDA 21 CFR 177.1630, EU Commission Regulation No 10/2011, and German LFGB food safety standard regulations.
Yes. We apply an food-grade anti-fog surfactant treatment inline during sheet extrusion. This prevents moisture droplets from condensing inside the PET cover when hot baked products cool or when placed in cold supermarket displays (0°C to 4°C), ensuring 99%+ optical transparency is maintained on retail shelves.
CAD structural design drawings are returned within 24–48 hours. Physical samples from CNC prototypes take 3–5 working days. Once the sample is approved, mass production typically takes 15 to 25 calendar days. Ocean freight shipments depart from Shantou or Shenzhen ports, with average transit times of 14–18 days to US West Coast, 28–35 days to US East Coast/Europe, and 10–14 days to Southeast Asia/Australia.
Clamshell containers and bases are engineered with precise taper angles and stacking shoulder heights. This allows maximum nesting density without binding, fitting up to 35% more units per master carton and optimizing 40ft High Cube (HQ) container loads to significantly reduce per-unit landed freight costs.
