Unit price in thermoforming is dominated by material, cycle time and freight. Here is the full cost structure and the levers that actually move the number.
The notes below come from day to day production and export work with overseas buyers.
This category covers a family of products rather than a single item. In practice a buyer defines thermoformed food 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 gauge 0.30 to 1.20 mm; MAP and vacuum lidding options; 1 to 8 compartment layouts. Materials most often specified are Polylactic Acid, Polyethylene Terephthalate, Polypropylene, Polystyrene, 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 dairy tubs, takeaway containers, ready meal trays.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
| Polylactic Acid | 1.24 g/cm³ | 50-60 MPa | up to 55°C (HDT) |
| Recycled PET | 1.35-1.40 g/cm³ | 45-65 MPa | -40°C to 70°C |
Polystyrene is frequently the default selection here: HIPS is the default thermoforming sheet for food packaging and appliance liners.
Unit price in thermoforming is dominated by material, cycle time and freight. Here is where the money goes.
Ask your supplier to quote two gauges and two cavity layouts; the difference shows which lever is worth optimising for your volume.
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.
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.
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.
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.
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.
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.
Our team supplies thermoformed food trays to food and beverage customers worldwide, with samples, material certificates and full inspection reports available before mass production.
