Polypropylene (PP) and PC/ABS Alloy are the two most quoted options for flame retardant plastic products in industrial packaging projects. Both are widely available, but they behave very differently once they are in service.
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 flame retardant 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 halogen free and brominated systems; sheet, profile and moulded forms; CTI values above 600 V. Materials most often specified are Acrylonitrile Butadiene Styrene, Polypropylene, Polyvinyl Chloride, Polyamide, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the industrial packaging sector the decision is usually driven by drop protection and cost per pack, with recyclability as a secondary requirement. Typical end uses include stretch film, blister trays, protective foam.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Polyamide | 1.13-1.15 g/cm³ | 60-85 MPa | -40°C to 120°C |
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.
Polypropylene grades offer lowest density among commodity plastics, while PC/ABS Alloy brings balances PC toughness with ABS processability. For industrial packaging service the difference shows up in chemical resistance and in the long term behaviour under load.
In short: choose the first option when stiffness, heat and dimensional stability dominate; choose the second when impact, cost and processing speed matter more.
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.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
