If you specify Polyvinylidene Fluoride (PVDF) for pharmaceutical blister packaging, a handful of properties decide whether the part survives forming and service. These are the values worth checking on every data sheet.
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 pharmaceutical blister packaging 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 cavity layouts 4 to 30 tablets; film gauge 200 to 350 micron; push through and peelable lidding. Materials most often specified are Polyvinylidene Fluoride, Polyethylene Terephthalate, Polyvinyl Chloride, Polypropylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the medical and pharmaceutical sector the decision is usually driven by validated sealing and sterilisation compatibility, with traceability as a secondary requirement. Typical end uses include diagnostic packs, surgical kit trays, pharmaceutical blisters.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Polyvinylidene Fluoride | 1.78 g/cm³ | 35-55 MPa | -40°C to 150°C |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
Polyvinylidene Fluoride is frequently the default selection here: PVDF is specified where both chemical resistance and purity are mandatory, such as UPW loops.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
Density 1.78 g/cm³, tensile strength 35-55 MPa, continuous service temperature -40°C to 150°C and melt range 170-180°C are the four values to circle on the data sheet. Everything else is secondary for most medical and pharmaceutical projects.
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.
These are the criteria that actually predict whether the part will perform in service.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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.
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.
