These are the questions our engineers hear most often when retail and merchandising buyers source thermoformed fruit and produce punnets, answered in plain language with the numbers that matter.
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 fruit and produce punnets 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 vented base and side walls; stack and nest geometry; 250 g to 2 kg formats. Materials most often specified are Recycled PET, Polyethylene Terephthalate, Polypropylene, Polylactic Acid, 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 pegboard blisters, promotional packs, counter displays.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polyethylene Terephthalate | 1.35-1.40 g/cm³ | 50-70 MPa | -40°C to 70°C |
| Recycled PET | 1.35-1.40 g/cm³ | 45-65 MPa | -40°C to 70°C |
| Polylactic Acid | 1.24 g/cm³ | 50-60 MPa | up to 55°C (HDT) |
Polylactic Acid is frequently the default selection here: PLA is compostable in industrial facilities, not in a backyard heap, so label it carefully.
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.
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.
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.
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.
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.
Our team supplies thermoformed fruit and produce punnets to retail and merchandising customers worldwide, with samples, material certificates and full inspection reports available before mass production.
