Thermoforming rewards designs that respect how a heated sheet stretches. These rules prevent most tooling rework and most thickness complaints.
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 Polyvinyl Chloride, Polypropylene, Polyethylene Terephthalate, Polyvinylidene Fluoride, 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, surgical kit trays, IV and catheter kits.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| 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 |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
Polyvinylidene Fluoride is frequently the default selection here: PVDF is specified where both chemical resistance and purity are mandatory, such as UPW loops.
Apply these points before the tool is cut; after that every change costs tooling and time.
Send these rules to your designer together with the sheet gauge and the target cycle time; most tooling modifications come from ignoring draft and corner radii.
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.
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.
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 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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
