Choosing the right thermoformed trays and blister packaging for energy and renewables applications is rarely about picking the cheapest quote. It is about matching resin properties, processing method and certification to the way the part will actually be 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 trays and blister packaging 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 clamshell and tray formats; cavity depth to 120 mm; sheet thickness 0.2 to 1.5 mm. Materials most often specified are Polyethylene Terephthalate, Polypropylene, Polyvinyl Chloride, Polystyrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the energy and renewables sector the decision is usually driven by UV durability and flame retardancy, with electrical insulation as a secondary requirement. Typical end uses include wind blade components, cable jacketing, battery housings.
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 |
|---|---|---|---|
| Polylactic Acid | 1.24 g/cm³ | 50-60 MPa | up to 55°C (HDT) |
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
Polyethylene Terephthalate is frequently the default selection here: High IV PET resin is the reason a 1.5 L bottle can be light yet hold carbonation pressure.
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.
Each step below has its own control points, and skipping one of them is where most defects start.
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. 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.
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.
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 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.
Our team supplies thermoformed trays and blister packaging to energy and renewables customers worldwide, with samples, material certificates and full inspection reports available before mass production.
