Direct factory supply of precision-engineered paper-plastic containers, rigid structural bases, and crystal-clear recyclable covers for commercial bakeries and global retail chains.
As global environmental directives redefine commercial food packaging, procurement directors and packaging engineers face a critical mandate: transition to 100% recyclable, high-barrier clamshell containers without sacrificing operational line speed, structural stackability, or product margin.
Moving away from legacy unseparable multi-layer laminates, our factory specializes in mono-material rPET, PP, and virgin kraft-board hybrid structures designed for seamless circular kerbside recycling streams across Europe and North America.
Zero cross-contamination in sorting systems.Engineered with dual-stage perimeter detents, our thermoformed clamshell lids maintain a precise 5N to 12N retention force. This guarantees acoustic snap feedback during automated packing lines and eliminates field popping during transit.
Our proprietary food-contact internal anti-fog coating prevents condensation droplet formation when hot baked items or cold refrigerated produce are packaged, keeping product presentation crystal clear under supermarket LED lights.
Achieving structural rigidity and oxygen/moisture barrier protection while maintaining 100% recyclability requires advanced polymer engineering. Here is how our factory formulates high-performance substrates.
Utilizing up to 100% post-consumer recycled PCR flake, our thermoformed rPET clamshells match the optical glass-like transparency of virgin resin. They exhibit exceptional impact strength down to -20°C, perfect for chilled dessert containers and fresh sushi platters.
Key Density: 1.38 g/cm³ | Recycle Code: #1 PET
For hot-fill food applications, ready-to-eat takeout, and bakery items requiring reheating, our food-grade PP clamshells withstand temperatures up to +120°C. Engineered with ribbed sidewall geometry to preserve column crush resistance during hot delivery.
Key Density: 0.90 g/cm³ | Recycle Code: #5 PP
Rapidly renewable sugarcane fiber molded under high-tonnage hydraulic presses creates a bio-based rigid shell. Paired with water-based dispersion barrier coatings, these bio-clamshells provide oil resistance for up to 4 hours without PFAS chemicals.
PFAS-Free: 100% Fluorine Free | Compostable: EN 13432
Chaozhou Weiting Packaging Products Co., Ltd. operates in the epicenter of China's food packaging manufacturing cluster. Our vertical integration directly reduces your total cost of ownership (TCO).
Unlike trading desks that outsource mold production, we own CNC tooling equipment. We cut custom aluminum blister molds and steel die-lines in 5–7 working days, cutting sample turnaround time by 60% and eliminating third-party markups.
Our facility houses 12+ automated high-speed thermoforming units (including Mengxing blister formers and Zhongbo die-cutters). Continuous sheet extrusion and robotic stacking yield over 500,000 units daily, securing steady lead times even during Q4 retail spikes.
International ocean freight charges volume over weight. Our structural designers engineer specific draft angles (3° to 5°) and stack-stop lugs on every clamshell, allowing maximum nesting density without binding. Saves up to 35% in container volume.
Navigating complex international packaging directives is seamless when partnering with WTPack. Every production run is backed by comprehensive laboratory declarations.
Fully compliant with the EU Packaging and Packaging Waste Regulation (PPWR). We supply certificate dossiers proving minimum 30% post-consumer recycled (PCR) resin content to exempt buyers from local virgin plastic taxes.
All PET and PP resins, color masterbatches, and anti-fog additives strictly comply with US FDA food-contact standards. Migration testing reports issued per lot number prior to export clearance.
Engineered to meet California Extended Producer Responsibility (EPR) requirements. Clear resin identification codes (RIC 1-7) are molded into bottom surfaces to streamline MRF sorting.
For UK packaging distributors, our certified rPET packaging contains verified >30% recycled content under ISO 14021 standards, ensuring full relief from the UK Plastic Packaging Tax.

Our recyclable clamshell containers are tailored to solve specific operational challenges across four major commercial sales channels.
Designed with rigid corner columns to prevent crushing when stacked 6-high during rush hour delivery. Crystal lid clarity highlights intricate frosting details and delicate fruit tarts.
Equipped with tamper-evident perimeter snap latches. Guarantees safety in self-service open display cases while preserving moisture balance for pre-cut melon, berries, and packaged salads.
Leak-proof perimeter channels prevent sauce migration during last-mile motorcycle delivery. Fits standard thermal delivery bags while maintaining food temperature and integrity.
Custom offset CMYK printing, gold hot-foil stamping, and ribbon slots transform utilitarian clamshell containers into luxury holiday presentation boxes for festive chocolates and macaroons.
Direct answers to technical, commercial, and logistical questions frequently raised by corporate packaging buyers and supply chain directors.
For existing structural tooling where custom branding is applied via paper sleeve or base offset printing, our standard MOQ starts at 3,000 to 5,000 units per SKU. For fully custom thermoformed structures requiring a new aluminum mold or specialized die-cut tooling, the MOQ is 10,000 units. We allow buyers to combine multiple container sizes within a single 20ft or 40HQ container load to minimize freight overhead.
Our engineering team designs dual-stage mechanical detents and corner friction buttons into every blister mold. During manufacturing, inline optical sensors and manual pull-force testers measure lid retention force every 30 minutes. We calibrate closing tension to require between 5N and 12N of force, securing the lid against vibrations during transport while remaining easy for end-consumers to open.
Yes. With every production export lot, we issue a comprehensive Compliance Pack including material traceability declarations, Heavy Metal / REACH compliance reports, and food-contact migration test results matching US FDA 21 CFR 177.1630 or EU Regulation No 10/2011 standard requirements. Certificates of Origin (Form E, Form F, or General CO) are supplied standard.
3D digital die-lines and structural mockups are rendered within 48 working hours. Physical samples from existing molds ship within 3–5 days. Custom prototype aluminum molds require 7–10 days. Once pre-production samples are approved, mass production takes 15–25 days depending on batch volume. We recommend booking Q4 holiday inventory 6–8 weeks in advance.
All clamshell products are engineered with optimized draft angles to nest tightly. Containers are packed flat or nested in high-burst 5-ply corrugated export cartons, palletized with protective corner boards, and stretch-wrapped. This precise volumetric stacking increases container load density by up to 35% compared to non-nested designs, directly lowering per-unit freight costs from Shantou or Shenzhen ports.
