High Density Polyethylene (HDPE) and Polypropylene (PP) are the two most quoted options for plastic pipes and tubes in food and beverage projects. Both are widely available, but they behave very differently once they are in service.
The notes below come from day to day production and export work with overseas buyers.
This category covers a family of products rather than a single item. In practice a buyer defines plastic pipes and tubes 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 and opaque options; coils and straight lengths; SDR 11 / SDR 17 / SDR 26. Materials most often specified are Polyvinylidene Fluoride, Acrylonitrile Butadiene Styrene, Polycarbonate, High Density Polyethylene, 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, shrink sleeves, dairy tubs.
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 |
| Polyvinylidene Fluoride | 1.78 g/cm³ | 35-55 MPa | -40°C to 150°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
High Density Polyethylene is frequently the default selection here: HDPE combines toughness with chemical inertness, which is why it dominates pipe and tank markets.
High Density Polyethylene grades offer high impact strength even at low temperature, while Polypropylene brings lowest density among commodity plastics. For food and beverage service the difference shows up in chemical resistance and in the long term behaviour under load.
The practical decision usually comes down to the service environment: temperature, chemical exposure and expected lifetime.
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.
These are the criteria that actually predict whether the part will perform in service.

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.
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.
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.
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.
