APPLICATION ANALYSIS / FOOD
PP Mooncake and Food Tray Application Analysis
PP inner trays separate and present mooncakes and similar foods. Start with the food dimensions and box space, then check packing, stacking and removal with samples. For direct food contact, specify the food, temperature, contact time and destination market before agreeing the material and required tests.

01
Packaging requirement
Hold each product in a repeatable position, preserve presentation and support packing without making removal difficult.
02
Principal risks
- Loose or overly tight cavities
- Poor stacking or de-nesting
- Unverified food-contact conditions
03
Material rationale
PP is an option for food and mooncake trays that need formed support and easy packing. Select the resin grade and food-contact tests for the intended use.
04 / STRUCTURE
Structural design checkpoints
- Set cavity clearance from real product dimensions
- Use ribs and radii to balance support and forming
- Check flange, stacking and de-nesting with the outer box
05 / VALIDATION
Sampling and validation
Check fit, removal, appearance, stacking, packing method, transport behavior and applicable food-contact requirements using representative products and packaging.
06 / BUYER INPUT
Inputs for project assessment
- Product dimensions and weight
- Cavity count and orientation
- Outer-box internal dimensions
- Colour, quantity and reference sample
07 / BUYER QUESTIONS
Common buyer questions
01Is PP alone proof of food-contact suitability?
No. Resin grade, additives, processing and intended contact conditions require project validation.
02Why use the real mooncake during sampling?
It verifies cavity fit, removal and presentation with the actual product.
03What affects stacking?
Flange geometry, draft, cavity depth and packing method affect stacking and de-nesting.
