Correct handling and storage protect the performance of pharmaceutical blister packaging from the factory to the packing line. This guide covers stacking, climate, static and inspection.
Everything here can be checked on a real sample before you commit to a production order.
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 push through and peelable lidding; PVDF coated PVC for high barrier; child resistant and senior friendly options. Materials most often specified are Polyethylene Terephthalate, Polyvinyl Chloride, Polyvinylidene Fluoride, 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 pharmaceutical blisters, device trays, diagnostic packs.
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 |
| Polyethylene Terephthalate | 1.35-1.40 g/cm³ | 50-70 MPa | -40°C to 70°C |
| Polyvinylidene Fluoride | 1.78 g/cm³ | 35-55 MPa | -40°C to 150°C |
Polyvinylidene Fluoride is frequently the default selection here: PVDF is specified where both chemical resistance and purity are mandatory, such as UPW loops.
Most premature failures are installation issues rather than material failures.
Keep a small stock of spares from the same production lot to avoid colour mismatch later.
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.
The route below is the one most factories use for this type of part.
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.
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.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
