The QL-CakeRound Series is a two-piece round PET whole-cake container family in three retail-standard sizes — QL-6CT (Ø190mm) for 6-inch cakes, QL-7CT (Ø207mm) for 7-inch cakes and QL-8CT (Ø263mm) for 8-inch cakes. Every SKU pairs a scalloped clear dome lid with a matte black base, delivering a premium patisserie visual across your full cake-shelf range with one consistent brand aesthetic. The petal-edge dome geometry clears cream swirls, chocolate curls and whole-fruit toppings without crushing the decoration during retail display or last-mile delivery.
QUNLU presents the Round PET Whole-Cake Container with Scalloped Clear Dome Lid & Black Base — a premium solution designed for bakeries, patisseries, and foodservice brands that deman presentation, protection, and performance. This innovative whole-cake PET packaging line, available in 6", 7", and 8" diameters (models QL-6CT, QL-7CT, QL-8CT), blends crystal-clear visibility with sturdy structural design
- Crystal clarity: The scalloped dome lid is crafted from high-clarity PET to deliver exceptional visibility for cakes and specialty desserts. This clear cake container lets customers easily inspect texture, icing detail, and garnishes without opening the package
- Secure snap-fit: The lid and base use a precision snap-fit closure to prevent accidental openings while remaining easy for consumers to open and reseal for short-term storage. This clear cake container packaging design prioritizes both safety and convenience
- Food-safe PET: Made from food-grade PET, the clear cake container meets regulatory standards for direct food contact. The whole-cake PET packaging material is lightweight yet durable and fully recyclable where facilities exist
- Supermarkets and delis: Grocery retailers can use the clear cake container to create grab-and-go cake sections. The black base cake box lends a consistent, professional look across multiple SKUs
QUNLU’s round PET clear cake container integrates thoughtful design choices that address both aesthetic and operational needs. The scalloped dome lid is not merely ornamental; its geometry improves light refraction, enhancing perceived color and texture of frostings and glazes. The black base cake box creates contrast that makes product imagery more appealing on social media photographs and in-store displays
- Dimensional stability: The clear cake container material resists warping and maintains dome clarity under refrigeration and ambient conditions. This ensures the scalloped dome lid remains snug and visually flawless during shelf life
- Temperature performance: PET performs well across typical bakery storage temperatures. The clear cake container is suitable for chilled displays and brief refrigerated transport without fogging or structural compromise
① Three Retail-Standard Sizes — 6-inch / 7-inch / 8-inch covers the full range from small birthday cakes to family celebration and event tier cakes; one design language across the entire shelf.
② Scalloped Petal-Edge Dome Lid — decorative rim geometry lifts the container from a plain plastic box to a premium bakery-shelf visual; proven to differentiate against flat-edge competitors on cake-cabinet display.
③ Tall Dome Height (80-91mm) — clears cream swirls, chocolate ganache, buttercream flowers and whole-fruit toppings without crushing on any of the three sizes.
④ Clear-Lid + Black-Base Contrast — matte black base makes cream-white, chocolate-brown and berry-red cake tops visually pop through the clear dome; consistent brand look across birthday, wedding and event bakery programs.
⑤ rPET Ready — GRS-certified 30 / 50 / 100% recycled PET on all three sizes; samples 3-7 business days for seasonal bakery lead time.

The QL-CakeRound Series is three two-piece PET sets — each SKU is a scalloped clear dome lid snap-locked onto a matte black round base. The dome height (80-91mm) is calibrated to clear typical whole-cake decoration heights — buttercream swirls, chocolate curls, ganache pours, whole-strawberry or whole-cherry toppings — without deformation during palletized cold-chain transport.
All three sizes are thermoformed in a Class 100,000 clean room on KIEFEL (Germany) and ASANO (Japan) equipment. Lids and bases are bagged separately (50 lids/bag × 3 + 50 bases/bag × 3 into one carton) — bakery buyers can restock either half without opening a full 150-set case.
Custom services: GRS-certified rPET (30/50/100%) on all three sizes, adjusted carton counts for wedding-season and holiday peak windows. Additional base colors and printing / labelling are not offered on this range — the clear-dome + black-base aesthetic is the design.
Safety: BPA-Free · PFAS-Free · No heavy metals · FDA 21 CFR 177.1630 compliant
Zhejiang Qunlu built the QL-CakeRound tooling as a bakery-industry-standard 6/7/8-inch program — three base molds + three matching scalloped lid molds sharing one production window; buyers can lock in a full three-size assortment under one PO.
The scalloped petal-edge lid geometry requires a more complex thermoforming die than flat-edge alternatives — an in-house tooling capability that delivers the premium bakery-shelf visual competitors rely on trading agents to source.
90 minutes to Shanghai Port, 2 hours to Ningbo Port — competitive ocean freight and full export documentation for time-critical wedding-season and holiday bakery windows.

Q1: What cake sizes do the three SKUs fit?
QL-6CT fits a 6-inch (Ø15 cm) round cake; QL-7CT fits 7-inch (Ø18 cm); QL-8CT fits 8-inch (Ø20 cm). Interior diameter allows ~5 mm clearance between cake edge and container wall for easy in/out handling.
Q2: Will the dome height clear tall cake decorations?
Yes. Dome height is 80-91 mm depending on size — validated for typical buttercream swirl (~30-50 mm), chocolate curl garnish (~40-60 mm), whole-strawberry toppers (~35 mm) and layered ganache pours.
Q3: Why the scalloped petal edge on the lid?
The scalloped rim is a deliberate bakery-shelf differentiator — it reads as a premium patisserie container rather than a generic clamshell, without needing printed branding. Competitor flat-edge lids look industrial next to it on the cake cabinet.
Q4: Are the lid and base shipped separately or together?
Together in one 150-set carton — 50 lids/bag × 3 + 50 bases/bag × 3. The half-and-half bagging lets a bakery restock lids or bases separately without opening a full case.
Q5: Is GRS-certified rPET available on all three sizes?
Yes. 30 / 50 / 100% recycled PET is available on QL-6CT, QL-7CT and QL-8CT lids and bases. Chain-of-custody documentation issued per shipment.
Q6: Can I lock in production for wedding season or holidays?
Yes. For wedding-season peak (Apr–Oct) and holiday cake windows (Christmas / Lunar New Year), we recommend PO confirmation 60 days before ship-out — sampling 3–7 days, production 15–20 days, plus ocean transit.
Q7: How do I request a quote?
Send size mix (QL-6CT / 7CT / 8CT), target quantity, destination port and PET vs rPET preference — reply within 24 hours.
