Clear heat sealing film combines visual access to the plate with a thermally bonded seal. Compare a strong, non-peelable construction with a peelable/pierceable construction, and select the exact grade for your plate resin and downstream access.

| Component | Function |
|---|---|
| Polyester carrier | A continuous clear film; round impressions in demonstration photographs are not holes. |
| Heat-sealing layer | Determines the resin match and peel behavior. |
| Wound roll | Core geometry and winding direction are part of equipment compatibility. |
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 roll dimensions | Post-seal access |
|---|---|---|---|
| Strong, non-peelable clear film | 65 ± 10 µm | 115 or 130 mm × 300 m | Not designed for peel removal |
| Peelable / pierceable clear film | 70 ± 10 µm | 80 or 115 mm × 300 m | Assess peel force and piercing method |
| Item | Selection information |
|---|---|
| Sealing method | Heat sealing |
| Carrier material | Polyester for listed reference grades |
| Feed format | Rolls; confirm machine requirements |
| Selection factors | Plate resin, sealing window, removal method and optical workflow |
For sample plates and laboratory workflows requiring a clear thermally sealed cover. Select the permanent or removable grade around the entire workflow, including any later sampling, assay readout and storage.
Photos illustrate the peelable/pierceable clear grade, not the non-peelable option. Rings on lifted film are seal impressions in a continuous sheet. Plate not included.
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.
No. The strong-seal configuration is non-peelable. Specify removability before ordering.
No. A pierceable continuous film has no intentional access cuts unless the selected specification explicitly includes them.
Send the model and film-feed requirements, including core, width, winding direction and roll outside diameter, together with the plate specification.
Send your plate and application details to Puretest for configuration review, sample availability and a quotation.
