Choosing the right CPET dual ovenable trays for food and beverage applications is rarely about the cheapest unit price. It is about sheet material, gauge, tooling and validation matching the way the pack or part is used.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines CPET dual ovenable trays by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include single and multi compartment; gauge 0.50 to 1.20 mm; oven safe to 220°C and freezer to -40°C. Materials most often specified are Polyethylene Terephthalate, Recycled PET, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the food and beverage sector the decision is usually driven by food contact compliance and migration limits, with seal integrity as a secondary requirement. Typical end uses include fresh produce punnets, dairy tubs, bakery inserts.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Recycled PET | 1.35-1.40 g/cm³ | 45-65 MPa | -40°C to 70°C |
| Polyethylene Terephthalate | 1.35-1.40 g/cm³ | 50-70 MPa | -40°C to 70°C |
Recycled PET is frequently the default selection here: Food-grade rPET requires a recognised recycling process plus solid-state polycondensation.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
The route below is the one most factories use for this type of part.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
Use this checklist when comparing two or three supplier quotations.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.
Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.
For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.
Standard packing is export cartons on fumigation-free pallets, with custom labelling, barcode and retail packing available. We also handle consolidated containers and door to door delivery.
A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.
If you are planning a new food and beverage project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
