Medical and healthcare buyers increasingly specify plastic films and flexible packaging instead of metal, wood or glass. Here is where they are used, why they work, and what to watch out for.
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 plastic films and flexible 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 thickness 12 to 200 micron; corona treated surface; custom printed up to 8 colours. Materials most often specified are Polypropylene, Polyethylene Terephthalate, Polylactic Acid, Low Density Polyethylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the medical and healthcare sector the decision is usually driven by biocompatibility and sterilisation stability, with full traceability as a secondary requirement. Typical end uses include surgical instrument handles, IV sets and tubing, diagnostic consumables.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
| 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 |
| Polylactic Acid | 1.24 g/cm³ | 50-60 MPa | up to 55°C (HDT) |
Low Density Polyethylene is frequently the default selection here: LDPE is the workhorse of flexible packaging because of its softness and sealing behaviour.
Typical medical and healthcare users specify this product for the following jobs.
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.

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.
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.
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.
