Rectangular PET Cake Container with Deep Clear Dome Lid & Textured Black Base | 247×147×90mm | Long Cakes | GHW-GD-250T/B

QUNLU presents the Rectangular PET Cake Container with Deep Clear Dome Lid & Textured Black Base (247×147×90mm) — a carefully engineered long cake packaging solution designed to showcase, protect, and preserve premium pastries and confections. This PET cake container combines visual appeal with functional performance, delivering a reliable option for bakeries, patisseries, catering services, and retail operations seeking high-quality long cake packaging.

At the heart of this offering is the PET cake container’s use of high-clarity polyethylene terephthalate (PET). The deep clear dome lid provides an unobstructed view of the cake while remaining lightweight and durable. PET’s inherent transparency ensures that colors and textures of cake decorations are rendered accurately, making the clear dome lid essential for visual merchandising.

Applications

This PET cake container is versatile across a wide range of applications

- Bakery Retail: Ideal for selling long cakes such as loaf-style cakes, rectangular celebration cakes, tiramisu loaves, and layered desserts where presentation matters. The clear dome lid ensures the product attracts attention on shelves.

- Catering and Events: For event caterers, the container provides a transport-ready solution for delivering long cakes to venues while maintaining decoration integrity.

- Online Ordering and Delivery: With e-commerce food sales increasing, the PET cake container protects cakes during courier transit and presents them beautifully upon un-boxing.

Innovation and Technical Advantages

QUNLU’s Rectangular PET Cake Container introduces several practical innovations that address common pain points in long cake packaging:

- Cleared Height for Decoration Protection: The deep clear dome lid addresses the perennial challenge of protecting tall icings and decorative elements. By providing additional headroom without compromising clarity, it reduces the risk of damage during handling.

- Visual Contrast from Textured Base: The textured black base is not merely aesthetic; it functions to enhance visual contrast, making the cake appear more vivid under display lighting. This perceived quality boost can influence purchasing decisions in retail environments.

- Optimal Structural Rigidity: PET offers a balance of rigidity and flexibility. The container’s engineered geometry provides resistance to bending and crushing, particularly important for long cake packaging where weight distribution can cause stress.

- Anti-Glare and Anti-Fingerprint Finish: The combination of a clear dome lid with an anti-glare finish and a textured base minimizes distracting reflections and finger smudges, ensuring the cake looks pristine during display and inspection.

- Efficient Footprint for Storage and Display: The rectangular shape maximizes usable cake area while minimizing wasted space in refrigeration units and display cases. This efficient footprint contributes to lower storage costs and improved inventory management.

Performance in Real-World Conditions

Durability: The PET cake container resists cracks and deformation under typical retail and delivery conditions. The secure closure keeps cakes intact through handling cycles.

① Deep 90mm Dome Lid — clears tall mille-feuille layers, cream swirls and decorative toppings that shallow-lid competitors crush during transport.

② Rectangular Long-Format Footprint — 247×147mm fits full long cakes, sliced tray-bake portions and multi-layer mille-feuille in one container.

③ Textured Black Base — diamond-pattern texture on the base grips the cake bottom to prevent sliding during last-mile delivery; provides premium contrast for cream, chocolate and fruit toppings under the clear dome.

④ Side Snap-Lock Ears — audible click-lock closure on both long sides stays sealed under chilled cold-chain and delivery-bag transport (14°F / -10°C to 140°F / 60°C).

⑤ rPET Ready — GRS-certified 30 / 50 / 100% recycled PET on both lid and base; samples 3-7 business days.

The GHW-GD-250 is a two-piece PET set — a deep clear dome lid (GHW-GD-250T, 41 g) snap-locked onto a rectangular textured black base (GHW-GD-250B, 39 g). The 90mm dome height clears typical long-cake decoration heights — mille-feuille cream layers (~40-60 mm), buttercream swirls, whole-strawberry toppers and layered ganache — without deformation during palletized cold-chain transport.

The base carries a diamond-pattern textured surface that grips the cake bottom, preventing the sliding-on-flat-plastic issue that plagues generic rectangular cake boxes on delivery-bag transport. Side-mounted snap-lock ears deliver an audible closure feedback so packing-line operators can confirm every seal.

Thermoformed in a Class 100,000 clean room on KIEFEL (Germany) and ASANO (Japan) equipment. Custom services: GRS-certified rPET (30/50/100%), custom base tints on request, adjusted carton counts for wedding-season and holiday peaks.

Safety: BPA-Free · PFAS-Free · No heavy metals · FDA

Zhejiang Qunlu built the GHW-GD-250 tooling around the long-format bakery gap — most rectangular cake boxes ship with a shallow 40-50mm lid that crushes mille-feuille and layered tray-bake; the GHW-GD-250 90mm dome is specifically calibrated to that category.

The textured base is an in-house thermoforming detail — the diamond pattern requires a more complex die than a flat base, giving buyers a functional grip surface (not decorative) that keeps cakes stable in delivery bags.

Q1: What cake dimensions does the 247×147×90mm container fit?

Interior fits a cake footprint up to ~230×130mm and ~80mm tall — one full long-format cake, a 4-slice tray-bake row, or a 3-4 layer mille-feuille stack.

Q2: Will the 90mm dome clear mille-feuille and layered tray-bake?

Yes. 90mm is deliberately deeper than the industry-common 40-50mm rectangular cake lid — validated for mille-feuille cream layers (~40-60 mm), buttercream tops and whole-fruit toppers without crushing.

Q3: Does the textured base really prevent cake sliding in delivery?

Yes. The diamond-pattern base surface increases friction against the cake bottom, keeping the cake seated during delivery-bag tilt and last-mile handling — a common pain point with flat-base competitor containers.

Q4: Are the lid and base shipped in the same carton?

Yes. 100 sets/ctn — 50 lids/bag × 2 + 50 bases/bag × 2 packed together in one 510×310×510mm carton. Order any mix ratio if you need lids-only or bases-only restock — contact us.

Q5: Can I get a base color other than Black?

Yes. Black is stock; custom PMS-matched base tints (dark green, brown, custom brand color) are available with a small tint-adjustment MOQ. Clear dome lid remains standard.

Q6: Is GRS-certified rPET available?

Yes. 30 / 50 / 100% recycled PET on both lid and base. Chain-of-custody documentation issued per shipment.

Q7: How do I request a quote?
