Key Features
Transparent • Rectangular • Stackable
Engineering Focus
Rectangular tooling demands lengthwise symmetry, balanced material flow across unequal sides, and consistent clarity — every dimension affects appearance, stackability and production yield.
Rectangular Symmetry & Straightness
Precision CNC-machined cavity maintains perfect parallelism between opposing long and short sides — eliminating taper, ensuring consistent wall height and uniform lid fit all around.
Balanced Material Flow & Thickness
Vacuum porting and draw ratios are calculated specifically for rectangular geometry — compensating for longer side stretch, preventing thin spots at corners, preserving PET clarity across the entire part.
Transparency-Optimized Surface Finish
Fine graded polishing minimizes light scattering — PET appears crystal-clear with premium gloss. Surface also improves release, reduces sticking and maintains appearance through high-volume runs.
Stacking Strength & Lid Interface
Base rigidity, side-wall taper, stacking shoulder and sealing flange are engineered together — stable vertical stacking, automated handling compatibility, reliable closure with matching lid.
Information Required for Customization
Provide these details so we can engineer rectangular geometry, PET forming profile and interface exactly for your project.
Box Dimensions
Length × Width × Height, inner usable space, corner radius, flange width & profile — 2D/3D drawing or physical sample
PET Material Specs
Sheet thickness, clarity grade, food-contact standard, allowable draw ratio and target cycle time
Stack & Lid Interface
Stack height requirement, nested/non-nested design, matching lid drawing or sample, sealing method & closure type
Machine & Service Mode
Thermoforming machine model, cavity count, OEM build-to-print or ODM design optimization, production volume & expected tool life
Frequently Asked Questions
What makes rectangular box moulding different from square?
Length and width differ significantly — material stretches unevenly along long vs short sides. We tune vacuum and draw ratios independently for each axis to prevent thin long sides and maintain clarity across the full rectangle.
Can you ensure uniform clarity and thickness all around?
Yes — vent layout is balanced for rectangular geometry; draw depth is calculated separately for long/short directions; surface finish is applied uniformly; all combine to deliver consistent PET clarity and wall thickness.
OEM vs ODM — which fits my project?
OEM: you provide design/sample — we build exact tooling to your specs. ODM: you state requirements — we propose optimized rectangular dimensions, corner radii, stack design and flange profile, then customize with your branding.
Can rectangular base and lid be built as a matched set?
Absolutely — we engineer both cavities together with aligned sealing flanges, matching corner radii, coordinated cooling and synchronized forming characteristics for perfect fit every cycle.
What about longer thin sides sagging or warping?
Side-wall taper, reinforcing ribs, cooling distribution and flange rigidity are all designed to counteract sag and warping — maintaining straight vertical sides and consistent flatness at production speed.
What information do I need to start?
Outer dimensions (L×W×H) or drawing/sample, PET thickness & clarity grade, corner radius preference, stack requirements, lid interface details and whether OEM or ODM service is needed.
Discuss Your Transparent Rectangular Cake Box Mould Project
Share your rectangular box drawing or sample, PET material specifications, dimensions and corner radius preference. Specify whether you need OEM build-to-print or ODM design support, plus any matching lid requirements. Our team will review rectangular geometry, clarity optimization and stackability before preparing your quotation.
