Custom CPET trays can be designed by size, capacity, shape, compartment layout, depth, color, rim design, sealing film compatibility, embossing, branding and private mold development. They are widely used for ready meals, frozen meals, airline meals, meal prep, central kitchens and ovenable food packaging.
For most B2B food brands, the most important custom options are:
| Custom Option | Why It Matters |
|---|---|
| Size and capacity | Controls portion size, cost and meal presentation |
| Compartments | Separates rice, sauce, protein, vegetables or side dishes |
| Tray depth | Affects filling volume, stacking and reheating |
| Color | Supports brand image and retail shelf appeal |
| Rim design | Determines heat sealing and leak resistance |
| Material thickness | Balances rigidity, cost and weight |
| Mold design | Creates a unique tray for your product line |
| Lidding film compatibility | Supports sealing, MAP, freezing and reheating |
| Embossing or logo | Adds brand identity without printed labels |
| Food-contact compliance | Required for export and high-temperature use |
The best custom CPET tray is not just attractive. It must work with your food, sealing machine, cold chain, oven or microwave instructions, retail channel and production budget.

Custom CPET trays are ovenable food packaging trays made from crystallized PET and designed to match a specific food product, brand or production process.
Unlike standard stock trays, custom CPET trays can be developed around your exact requirements, such as:
Meal portion size
Product weight
Number of compartments
Sauce separation
Freezer-to-oven performance
Microwave and oven heating
Airline cart size
Tray sealing machine compatibility
Retail presentation
Brand color
Private mold design
CPET is commonly used because it can handle freezing, chilled storage, microwave reheating and conventional oven heating. Many CPET trays are commonly specified for a temperature range around -40°C to 220°C, depending on supplier testing and tray design.
Standard CPET trays are often enough for early-stage products or small-volume programs. But custom CPET trays become valuable when packaging affects product quality, branding, shelf appeal or production efficiency.
Food brands choose custom CPET trays to:
Improve meal presentation
Control portion size
Reduce food movement during transport
Prevent sauce migration
Improve sealing performance
Fit existing packing lines
Fit airline carts or retail shelves
Reduce tray weight
Improve stacking and denesting
Create a unique brand appearance
Support premium ready meal positioning
For B2B buyers, customization is usually about performance first and branding second.
Tray size is one of the most important decisions because it affects meal portion, sealing area, carton packing, pallet loading and shipping cost.
Common custom tray formats include:
Small single-serve trays
Medium ready meal trays
Large family meal trays
Airline meal trays
Meal prep trays
Rectangular trays
Round trays
Oval trays
Square trays
Shallow trays
Deep trays
When choosing a tray size, consider:
| Factor | Buyer Question |
|---|---|
| Food weight | How many grams or ounces will the meal contain? |
| Capacity | What ml or oz volume is needed? |
| Headspace | Is there enough space for sealing and reheating? |
| Shelf space | Will the tray fit retail displays or cartons? |
| Oven fit | Will it fit consumer ovens, aircraft ovens or catering ovens? |
| Carton loading | How many trays fit per carton and pallet? |
| Cost | Does the size increase material use or freight cost? |
A custom tray should be designed around both food performance and logistics efficiency.
Compartments are especially important for ready meals, airline meals, meal prep and institutional catering.
Common options include:
Multi-compartment meal trays
Sauce-separated trays
Protein-and-side trays
Rice-and-curry trays
Single-compartment trays are best for meals where ingredients can be served together.
Typical applications:
Pasta
Lasagna
Curry
Rice dishes
Sauced meals
Baked meals
They are simple, cost-effective and easier to seal.
Two-compartment trays help separate the main dish from a side dish.
Typical applications:
Rice and protein
Pasta and vegetables
Curry and rice
Meat and potatoes
Airline hot meals
The divider must be designed to prevent sauce migration during storage, transport and reheating.
Three-compartment trays are useful for complete meals with multiple components.
Typical applications:
Meal prep
Airline meals
School meals
Hospital meals
Diet meals
Premium ready meals
For multi-compartment CPET trays, sealing performance across internal dividers should be tested carefully.
Shape affects appearance, denesting, sealing, machine compatibility and shelf presentation.
| Shape | Best For |
|---|---|
| Rectangular CPET trays | Ready meals, frozen meals, airline meals |
| Round CPET trays | Soups, rice bowls, pasta bowls |
| Oval CPET trays | Premium meals and retail presentation |
| Square CPET trays | Meal prep and modern retail packaging |
| Custom-shaped trays | Brand differentiation and unique food formats |
Rectangular trays are the most common because they are efficient for packing, stacking and sealing. Custom shapes can improve brand identity, but they may increase mold cost and require more testing.

Tray depth controls food volume, portion control, heat distribution and consumer handling.
A shallow tray may improve presentation and reheating speed. A deeper tray may hold more food and reduce leakage risk for sauced meals.
When designing tray depth, test:
Food fill level
Sauce movement
Heat distribution
Sealing headspace
Consumer handling
Stack height
Denesting performance
Carton and pallet efficiency
Do not design the tray only around volume. A tray that holds the right amount of food may still fail if it does not seal, stack or reheat well.
CPET trays can often be made in different colors depending on MOQ, material availability and supplier capability.
Common color options include:
Black CPET trays
White CPET trays
Natural CPET trays
Dual-color CPET trays
Custom brand-color trays
Black CPET trays are popular for premium ready meals because they make food colors stand out and create strong shelf appeal.
White CPET trays can create a clean, fresh and institutional look. They are often suitable for healthcare, school meals and certain retail meal ranges.
Custom colors can help brand differentiation, but buyers should check:
MOQ
Color consistency
Food-contact safety
Recyclability impact
Optical sorting compatibility
Lead time
Material availability
For sustainability-focused markets, tray color should be discussed together with recycling requirements.
Material thickness affects tray rigidity, heat resistance, weight and cost.
A thicker tray may provide:
Better rigidity
Stronger handling
Better stacking
Better performance with heavy meals
Lower deformation risk
A thinner tray may provide:
Lower material cost
Lower packaging weight
Better sustainability profile
More efficient shipping
The right thickness depends on the food weight, tray size, heating method, sealing process and distribution conditions.
The tray rim is one of the most important parts of a custom CPET tray. A beautiful tray can still fail if the rim does not seal properly.
A good sealing rim should be:
Flat
Consistent
Wide enough for sealing
Compatible with lidding film
Stable under heat and pressure
Free from deformation
Suitable for automatic tray sealing machines
Rim design affects:
Leak resistance
Peel strength
MAP performance
Seal consistency
Production speed
Consumer opening
If your tray will be heat sealed, design the rim before finalizing the mold.
Custom CPET trays should be designed together with the lidding film. The tray and film work as one packaging system.
Lidding film options include:
Peelable lidding film
Weld seal film
Anti-fog film
Ovenable film
Microwave-safe film
High-barrier MAP film
Printed lidding film
For ready meals, the film should be tested for:
Seal strength
Peel performance
Leak resistance
Freezer performance
Oven or microwave use
Anti-fog clarity
MAP shelf life
Food-contact compliance
Do not wait until after the mold is finished to choose the film. Film compatibility should be part of the design stage.
Modified atmosphere packaging can help extend shelf life for chilled ready meals and other prepared foods. If the tray will be used for MAP, the custom design should support gas flushing and strong seal integrity.
MAP tray design should consider:
Headspace
Rim flatness
High-barrier lidding film
Seal strength
Gas retention
Oxygen transmission rate
Food shelf-life target
Production line speed
Leak testing
For MAP applications, tray design and film selection must be validated together.
CPET trays can support branding in several ways:
Custom color
Custom shape
Embossed logo
Debossed logo
Printed lidding film
Paper sleeve
Label
Retail carton
Custom compartment layout
Embossing can add subtle brand identity to the tray, but it should not interfere with sealing, stacking or food release.
For retail ready meals, the strongest branding usually combines tray color, shape, sleeve design and clear food presentation.
A private mold is used when standard tray sizes cannot meet your product or branding requirements.
Private mold development may be useful when you need:
Unique dimensions
Special compartments
Airline cart compatibility
Premium retail presentation
Better portion control
Improved sealing area
Lower material weight
Unique brand identity
Long-term packaging exclusivity
A typical custom CPET tray project includes:
Requirement discussion
Food sample and portion analysis
Tray sketch or 3D design
Mold feasibility review
Prototype or sample tooling
Trial production
Sealing and reheating tests
Freezer and transport tests
Food-contact compliance review
Final mold approval
Mass production
Custom mold projects should be planned early because design, tooling, testing and approval can take time.
MOQ and lead time depend on the tray size, color, material, mold status and order complexity.
In general:
| Project Type | Typical Consideration |
|---|---|
| Stock tray | Lower MOQ, faster lead time |
| Custom color stock mold | Higher MOQ than standard color |
| Custom printed film | MOQ depends on film supplier |
| Private mold tray | Tooling cost and longer development time |
| Large-volume OEM project | Better unit cost after mold approval |
Buyers should ask suppliers for:
MOQ for standard trays
MOQ for custom colors
MOQ for private mold production
Mold cost
Sample cost
Prototype lead time
Mass production lead time
Carton and pallet quantity
Export packaging details
Custom CPET trays for food packaging must meet food-contact requirements in the target market.
Depending on your market, you may need:
FDA food contact compliance
EU food contact compliance
LFGB testing
Overall migration test
Specific migration test
Heavy metal testing
BPA-free declaration
BRC or ISO documentation
Traceability records
High-temperature food contact testing
For ovenable meals, testing should reflect the real heating condition, food type and contact time.
Before mass production, test the tray with your actual food and process.
Check portion size, food appearance, headspace and compartment separation.
Test the tray with the selected lidding film and sealing machine.
Test with sauces, oils and liquids after filling, cooling, transport and reheating.
Freeze the tray and check cracking, brittleness, film lifting and tray deformation.
Heat the tray according to final consumer instructions and check shape stability.
Check heat distribution, tray stability and steam release.
Make sure trays stack, separate and feed smoothly on production lines.
Simulate carton packing, vibration, drop and pallet handling.
For chilled or MAP meals, validate microbiological and sensory shelf life.
