Polylactic Acid (PLA) and Recycled PET (rPET) are the two most quoted options for recycled plastic products and compounds in food and beverage projects. Both are widely available, but they behave very differently once they are in service.
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 recycled plastic products and compounds 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 food contact and non-food grades; pellet, flake and finished part forms; PCR content 30% to 100%. Materials most often specified are Polystyrene, Recycled PET, Polypropylene, 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, takeaway trays, dairy tubs.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Polylactic Acid | 1.24 g/cm³ | 50-60 MPa | up to 55°C (HDT) |
| Recycled PET | 1.35-1.40 g/cm³ | 45-65 MPa | -40°C to 70°C |
Polylactic Acid is frequently the default selection here: PLA is compostable in industrial facilities, not in a backyard heap, so label it carefully.
Polylactic Acid grades offer bio-based and industrially compostable, while Recycled PET brings lower carbon footprint than virgin resin. For food and beverage service the difference shows up in impact strength 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.
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.

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.
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.
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 recycled plastic products and compounds to food and beverage customers worldwide, with samples, material certificates and full inspection reports available before mass production.
