Aluminum heat sealing foil is bonded to a compatible microplate using a controlled heat-sealing process. Choose a foil grade by plate resin, required peel or piercing behavior, and the feed format supported by your sealer.

| Component | Function |
|---|---|
| Aluminum layer | The opaque carrier provides the foil surface shown in the product images. |
| Heat-sealing layer | Chosen for the plate resin; compatibility is not universal. |
| Roll or precut sheet | Width, core and winding requirements determine feed 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.
| Reference grade | Nominal thickness | Sheet / roll dimensions | Removal and fit |
|---|---|---|---|
| Thin foil grades | 25 ± 5 µm | 125 × 80 mm sheets; 80 or 115 mm × 300 m rolls | Peelable and non-peelable grades differ; match plate resin. |
| Thicker peelable grade | 50 ± 5 µm | 125 × 80 mm sheets; 80 mm × 300 m rolls | Confirm peel force and selected plate compatibility. |
| Item | Selection information |
|---|---|
| Sealing method | Thermal sealing with a compatible heat sealer |
| Carrier | Aluminum |
| Roll requirements | Width, roll length, core diameter, outside diameter and winding direction |
| Process qualification | Exact plate resin, rim design, sealer settings and access method |
For microplate sample preparation, storage and other qualified sealing workflows using manual, semi-automatic or automated heat sealers. Select a grade explicitly suited to the intended assay and post-seal handling.
Thin foil reference shown as a roll and peeled from a 384-well demonstration plate. Square marks are sealing impressions, not perforations. 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.
Only if a compatible heat sealer and qualified plate/foil process are available. Heat foil and adhesive foil use different bonding methods.
Thickness alone does not determine suitability. Consider peel force, piercing needs, plate resin and the sealer’s operating window.
The photo demonstrates peeling on a 384-well plate. The foil must be selected by the full sealing area and plate resin, not solely by well count.
