Food and beverage buyers increasingly specify thermoformed bakery trays and inserts instead of injection moulding or corrugated board. Here is where they are used and why they work.
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 thermoformed bakery trays and inserts 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 clear and coloured options; perforated and vented bases; gauge 0.25 to 0.70 mm. Materials most often specified are Polystyrene, Polylactic Acid, Recycled PET, Polyethylene Terephthalate, 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 ready meal trays, bakery inserts, fresh produce punnets.
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 |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Polyethylene Terephthalate | 1.35-1.40 g/cm³ | 50-70 MPa | -40°C to 70°C |
Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.
The list below covers both high volume and specialised uses.
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.
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.
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.
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.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
