Importing food grade plastic containers from China can cut unit cost substantially, but only if the specification, the tooling and the inspection plan are agreed before the first shipment.
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 food grade plastic containers 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 in mould labelling; microwave safe PP grades; tamper evident closures. Materials most often specified are High Density Polyethylene, Polystyrene, Polyethylene Terephthalate, Polypropylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the logistics and warehousing sector the decision is usually driven by impact protection and load rating, with stackability as a secondary requirement. Typical end uses include protective dunnage, returnable pallets, strapping.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°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 landed cost of food grade plastic containers is built from several layers:
Before placing an order, work through this checklist:
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.
Work through these points in order and most specification mistakes disappear.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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.
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.
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.
Our team supplies food grade plastic containers to logistics and warehousing customers worldwide, with samples, material certificates and full inspection reports available before mass production.
