Breathable heat sealing film is a gas-permeable cover bonded with a heat sealer. It brings a thermal sealing step to plate-culture workflows that require gas exchange, with sheet and roll configurations selected around the equipment and plate.

| Component | Function |
|---|---|
| Breathable membrane | A white membrane rather than a clear optical film or opaque metal foil. |
| Heat-sealing interface | Bonds to compatible plate rims using controlled heat and pressure. |
| Supply format | Precut sheets or a continuous roll for the selected sealer. |
Use the configurations below to specify your inquiry. Dimensions and thicknesses are reference configurations, not a guarantee of stock or universal compatibility. The selected grade, usable sealing area, packaging and operating limits will be confirmed in the quotation and product specification.
| Configuration | Nominal thickness | Reference dimensions | Equipment consideration |
|---|---|---|---|
| Precut sheet | 90 ± 10 µm | 125 × 80 mm | Confirm plate coverage and sealer sheet handling. |
| Roll feed | 90 ± 10 µm | 80 mm × 500 m | Confirm core, roll diameter and winding direction. |
| Item | Selection information |
|---|---|
| Sealing method | Thermal sealing |
| Membrane behavior | Breathable; reference grade is peelable/pierceable |
| Material selection | Request the exact membrane and seal-layer specification |
| Qualification | Gas exchange, evaporation, plate compatibility and seal consistency |
For microplate culture and incubation workflows combining gas exchange with heat-sealer operation. Consider the culture’s oxygen demand, medium volume, incubation humidity and shaking alongside sealing equipment requirements.

For a useful quotation, send your plate model or drawing, preferred film construction, sheet size or roll-feed requirements, application conditions, quantity and destination country. For heat-seal products, include the sealer model. If lot-specific quality documents or special packaging are required, list them in the inquiry so they can be checked for the selected grade.
Evaluate a representative sample under your actual workflow before changing a qualified laboratory consumable. A general family description does not replace grade-specific test data.
The choice depends on equipment, throughput and plate compatibility. Heat sealing requires process qualification; adhesive sheets can be applied manually.
Choose according to the sample’s storage requirements. A gas-permeable cover may allow vapor loss and is not equivalent to an impermeable storage seal.
Provide sealer model, width, core diameter, permitted roll diameter and winding direction, plus plate model, annual usage and destination.
Send your plate and application details to Puretest for configuration review, sample availability and a quotation.
