The IPL-7TB and IPL-8TB are two-piece rectangular cake boxes combining a clear PET flat lid with a black-gold PET base — available in two sizes for different cake formats. The 177×80mm format fits standard rectangular cake slices and Swiss roll portions; the 157mm (157×77mm) accommodates wider individual cake formats. Both sizes feature a black PET base exterior for a clean, professional counter presence and a gold-laminated interior that frames the cake from below — visible through the clear flat lid at the point of display. The two-piece construction allows the black-gold base to be filled and plated independently before the flat lid is placed as the final presentation step.

① Black Exterior, Gold Interior — Two-Tone from One Material

The base is black PET on the outside — clean and professional on the counter. The interior surface is gold-laminated — framing the cake in a warm metallic tone that communicates premium without a premium packaging price. Both colors are integral to the PET material, not applied as surface coatings.

② Two Sizes — Match the Cake, Not the Other Way Around

IPL-7TB (177×80mm): standard rectangular cake slice, Swiss roll portion, or elongated individual dessert. IPL-8TB (157×77mm): wider format for broader cake slices, layered mousse, or two-piece petit four arrangements. Both share the same flat lid height (50mm) and the same black-gold base construction — choose the footprint that fits your specific pastry.

③ Flat Lid — Clean, Compact Presentation

The flat clear lid provides a clean, compact profile suitable for counter display and stacking — ideal for cake slices and pastries where a low-profile presentation is preferred over arched headroom., decorated mousse, and garnished Swiss rolls without lid contact. The flat profile minimizes overall package height, allowing more units per display shelf and tighter packing in delivery bags for multi-item orders. — from counter to customer.

④ Two-Piece Workflow — Fill First, Lid Later

Separate lid and base mean the gold-lined base can be pre-filled at the pastry bench without the lid obstructing access — then lidded at the display counter as the final touch. For bakery counters with separate prep and display stations, this decouples filling from finishing.

⑤ 400 Sets Per Carton — Higher Density for High-Volume Bakeries

Both the 177mm and 157mm sizes pack 400 sets per carton — with compact carton dimensions that maximize container utilization for importers and distributors running high-volume bakery packaging programs.

Two-Piece Flat Lid Construction

The IPL series uses a separate flat lid + base construction — different from the hinged clamshells and square two-piece boxes elsewhere in the QunLu range. The rectangular two-piece format with a dome arch is purpose-built for elongated cake slices and Swiss roll portions where length-to-width ratio matters: the rectangular footprint provides a natural frame for long, narrow pastries that would be awkwardly positioned in a square box of equivalent volume.

Flat Lid Profile

The 50mm total closed height provides a compact profile for both sizes — minimizing display footprint while accommodating standard cake slice and pastry heights. The flat lid rests on the base rim, providing a clean horizontal surface suitable for stacking on bakery display counters and in delivery packaging.

Black-Gold Base — Display Psychology

The black exterior presents as clean and professional on a white bakery counter — it doesn't compete visually with the cake. The gold interior creates a warm, reflective backdrop that frames the cake from below and catches the ambient counter lighting through the clear dome. Both colors are produced from the same PET sheet — the black is the base PET color and the gold is a laminated layer — not paints or post-form coatings.

177mm vs 157mm — Size Selection Logic

The length difference between 177mm and 157mm is the primary selection factor. The 177mm fits long rectangular formats: Swiss roll slices, elongated petit four arrangements, and standard cake shop individual slices. The 157mm accommodates wider formats while maintaining a compact footprint — broader layered mousse, tiramisu squares, and two-piece dessert arrangements work naturally in this proportion. Both use the same 50mm dome height and the same black-gold base construction — only the footprint differs.

Rectangular Flat Lid Forming — Balanced Material Draw

Producing a rectangular flat lid with a 50mm closed height in a two-piece format requires even material draw across an elongated shape — a different thermoforming challenge from square or hinged clamshell forming. The flat lid construction prioritizes even thickness across the horizontal surface — producing a clean, stackable top. The IPL series is produced on QunLu's KIEFEL and ASANO thermoforming lines using tooling specifically calibrated for rectangular flat lid profiles, maintaining consistent wall thickness across the lid surface to the snap-fit rim.

Both IPL sizes are produced from the same black-gold laminated PET material stock used for the GHW-061T/B — QunLu's PET sheet supply chain maintains pre-laminated black-gold PET in standard production stock, meaning the IPL base shares identical material, lead time, and quality characteristics as other QunLu black-gold products. This shared material platform allows mixed-SKU orders combining IPL bases with other black-gold base products in a single production run.

400 sets per carton for both sizes, compact carton dimensions — IPL-7TB: 65×41×19 cm, IPL-8TB: 65×41.5×17 cm. Ships from Pinghu, Jiaxing, Zhejiang via Shanghai or Ningbo port. Full documentation: FDA, ISO 22000, BRC, GRS.
