Choosing the right thermoformed egg trays and cartons for retail and merchandising 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.
This guide is written for engineers, purchasers and project managers who need a practical answer, not a resin data sheet.
This category covers a family of products rather than a single item. In practice a buyer defines thermoformed egg trays and cartons 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 stackable and nestable designs; clear and coloured; 6, 10, 12 and 18 cell formats. Materials most often specified are Polyethylene Terephthalate, Polystyrene, Polypropylene, Recycled PET, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the retail and merchandising sector the decision is usually driven by shelf presentation and print quality, with stack strength as a secondary requirement. Typical end uses include counter displays, pegboard blisters, promotional packs.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Recycled PET | 1.35-1.40 g/cm³ | 45-65 MPa | -40°C to 70°C |
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°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.
Processing method drives both cost and performance, so it should be fixed early in the design.
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.
These are the criteria that actually predict whether the part will perform in service.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
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.
Colour is controlled with a masterbatch reference approved by the customer, and every production lot is checked against the approved sample under standard lighting before shipment.
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.
Our team supplies thermoformed egg trays and cartons to retail and merchandising customers worldwide, with samples, material certificates and full inspection reports available before mass production.
