Choosing the right anti-static and ESD plastic products for food and beverage 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 anti-static and ESD plastic products 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 transparent conductive coatings; sheet, profile, tray and box formats; carbon filled and permanent antistat grades. Materials most often specified are Polypropylene, Polyether Ether Ketone, Polyvinyl Chloride, 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 beverage bottles, takeaway trays, bulk totes.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.
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.
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.
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.
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.
If you are planning a new food and beverage project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
