QUNLU presents the Triangle PET Single-Slice Cake Container with Clear Dome Lid — an elegant, practical solution designed to showcase and protect single-serving desserts with flair. Engineered for bakeries, patisseries, catering services, and dessert-focused retailers, this triangle cake container combines visual appeal, functional protection, and reliable portability.

Product Overview

The Triangle PET Single-Slice Cake Container with Clear Dome Lid is tailored for single-serving desserts such as mousse slices, fruit tarts, and small confections. The container’s triangular footprint is optimized to cradle slice shapes, providing a snug fit that reduces movement and protects delicate toppings and textures

Design and Materials

Crafted from high-clarity PET (polyethylene terephthalate), the triangle cake container offers excellent transparency, making the dessert the centerpiece. The clear dome lid is engineered to be crystal-clear and scratch-resistant, giving customers an unobstructed view of mousse layers, fruit arrangements, and glaze finishes. PET construction ensures food-safe contact, odor resistance, and recyclable potential where local facilities permit.

Application

Bakery and Patisserie: Ideal for bakeries presenting single slices of layered cakes, mousse slices, or premium fruit tarts. The triangle cake container frames each slice attractively, supporting branding and convenience.

Innovation and Technical Advantages

The Triangle PET Single-Slice Cake Container with Clear Dome Lid offers several technical advantages over generic packaging:

- Optimized geometry: The triangular footprint is specifically engineered for single cake slices, ensuring minimal lateral movement and preserving decorative details such as piped frosting, fruit pieces, or delicate chocolate garnishes

- High-clarity PET: The use of premium PET material enhances visual appeal and durability compared to standard plastics. It resists fogging in refrigerated environments and maintains optical clarity vital for product merchandising

- Versatile base finishes: The black gold base options allow bakeries to align packaging with seasonal marketing, limited editions, or brand identity—offering an immediate upgrade to perceived product value

Branding and Customization Opportunities

QUNLU understands the importance of brand recognition in the competitive dessert market. The triangle cake container supports multiple branding options:

- Custom labeling: The flat surfaces on the base and the clear dome lid provide areas for brand stickers, ingredient labels, or nutritional information

- Sleeve and banding: Branded sleeves or banding can be applied around the base to add color, product naming, or promotional messaging without obstructing the clear dome lid’s visibility

- In-mold printing compatibility: For higher-volume orders, in-mold or pad printing on the base can be utilized to permanently incorporate logos or brand elements

Customer Experience and Operational Benefits

End customers benefit from a visually attractive, easy-to-open container that keeps desserts intact and fresh. For businesses, the triangle cake container streamlines serving, reduces product loss from breakage, and improves shelf presence. Its stack ability and lightweight nature simplify inventory management and reduce shipping costs.

① Triangle Wedge Format for Single-Slice Cakes — 133×95×73mm shape purpose-designed for one portion of round-cake slice, mousse, cheesecake or fruit tart; no cake collapse against a rectangular wall.

②Two Base Finishes, One Universal Lid — matte Black for modern patisserie, PE-laminated Metallic Gold for wedding and event programs; both snap into the same QL-333T lid.

③ Snap-Lock Rim Seal — validated across 14°F / -10°C to 140°F / 60°C for chilled bakery display, cake-cart transport and event catering handoff.

④ rPET Ready — GRS-certified 30 / 50 / 100% recycled PET on both base colors; samples 3-7 business days for seasonal bakery lead time.

The QL-333 is a two-piece PET set — a tall clear lid (QL-333T, 11 g) snap-locked onto a triangle wedge base (QL-333B, 4 g). The dome geometry protects tall decorated slices — cream swirls, buttercream flowers, chocolate curls, whole-strawberry toppings — from crushing during retail display and event catering transport.

The Metallic Gold base is achieved through a food-contact-safe PE-laminated film applied to a food-grade PET substrate — not spray paint, not metallic dye. The PE film is qualified under ISO 22000, BRC, GRS and FDA food-contact standards. Both Black and Gold bases are thermoformed in a Class 100,000 clean room on KIEFEL (Germany) and ASANO (Japan) equipment.

Custom services: GRS-certified rPET (30/50/100%), adjusted carton counts for wedding-season peaks and event-catering programs.

Safety: BPA-Free · PFAS-Free · No heavy metals · FDA 21 CFR 177.1630 compliant

Zhejiang Qunlu built the QL-333 tooling as a bakery-industry-standard single-slice program — one triangle base mold + one dome lid mold, with two co-produced color runs (Black and PE-laminated Gold) sharing the same production window.

The Gold PE-film lamination is a dedicated in-house process — not outsourced — giving buyers a shorter lead time and traceable food-contact certification vs. spray-painted or vacuum-metallized alternatives on the market.

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: Do both base colors share the same dome lid?

Yes. The QL-333T clear dome lid snaps interchangeably onto the Black QL-333B and the Gold QL-333B bases. One lid SKU covers your entire two-color assortment.

Q2: Is the PE-laminated Gold finish food-safe?

Yes. The Gold effect comes from a food-contact-safe PE film laminated onto the food-grade PET base — not spray paint, not metallic dye. The complete assembly is certified under ISO 22000, BRC, GRS and FDA.

Q3: What single-serve cake weights does the 133×95×73mm wedge hold?

Fits one slice from a 6-inch cake cut into 6 wedges, or an 8-inch cake cut into 10 wedges. Typical fill: 80–120 g mousse / cheesecake, 100–150 g layered cake, 80–100 g fruit tart slice.

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

Separately. Bases pack 1800 pcs/ctn (100 per bag × 18) into a 570×365×350mm carton; lids pack 1800 pcs/ctn into a 660×380×360mm carton. Order any mix ratio of base + lid — you are not locked into 1:1.

Q5: Is GRS-certified rPET available on both base colors?

Yes. 30 / 50 / 100% recycled PET is available on Black, Gold and the clear dome lid. Chain-of-custody documentation issued per shipment.
