Product Overview and Key Features

The QUNLU rectangular deep PET cake box is precisely sized at 302×203×64mm to accommodate long cakes and multi-slice trays with space to spare. The deep PET cake box construction offers increased internal height compared with standard containers, allowing taller decorations and layered desserts to remain intact during handling. The clear dome lid cake tray integration provides maximum clarity for display, allowing customers to inspect intricate frosting, delicate toppers, and layered textures without exposing the product to contaminants.

Materials and Durability

Constructed from high-quality polyethylene terephthalate, the deep PET cake box offers excellent clarity, rigidity, and impact resistance while remaining lightweight. PET is a recyclable material that supports sustainability goals for food packaging. The clear dome lid cake tray element is molded from crystal-clear PET that resists fogging and maintains transparency under varied refrigeration conditions. The black wavy base dessert platter is crafted from a durable, textured PET blend that resists bending and protects delicate pastries during transit.

Zhejiang Qunlu built the QL-GD-10 tooling for catering-size long-format bakery — the 302mm footprint is one of the largest single-container two-piece cake formats on the market, filling the size gap above our QL-CakeRound 8-inch (Ø263mm) and GHW-GD-250 (247mm) SKUs.

The wavy-pattern base is an in-house thermoforming detail that requires a more complex die than a flat base, delivering both premium visual and functional cake-grip in one texture.

Q1: What cake dimensions does the 302×203×64mm container fit?

Interior fits a cake footprint up to ~280×180mm and ~55mm tall — one long rectangular cake, a full sheet-cake row, or 6-8 slice portions in a 2×3 or 2×4 grid.

Q2: Is 64mm dome tall enough for my product?

Suits cream-topped slices, layered mousse, cheesecake, short-tier bakery. For taller mille-feuille or whole-cake decoration, look at our GHW-GD-250 (90mm dome).

Q3: Is the wavy base pattern decorative or functional?

Both. The wavy texture reads as a premium patisserie visual under the clear dome, and increases grip against pastry bottoms to prevent sliding in delivery-bag tilt.

Yes. 400 sets/ctn packed together; carton dimensions TBD — please contact us for the current pack size.

Q5: Is GRS-certified rPET available?
