Arcfibre BL 710 Blister-Board Coating for PVC and PET
A water-based blister-board coating that bonds printed paperboard to a thermoformed PVC or virgin PET blister under heat and pressure. It is the standard bond grade of the subfamily, set for conventional platen sealing at moderate dwell and jaw temperature.

1. Product description
A water-based blister-board coating that bonds printed paperboard to a thermoformed PVC or virgin PET blister under heat and pressure. It is the standard bond grade of the subfamily, set for conventional platen sealing at moderate dwell and jaw temperature. Board grammage, moisture content and print coverage under the seal area all change the bond, and the target is consistent fibre tear on peel, so the window is established on the customer sealing machine.
2. Features
- Bonds printed board to thermoformed PVC and virgin PET
- Set for conventional platen heat sealing
- Target of consistent fibre tear on peel across the seal area
- Adhesive seal coating, not a barrier
3. Recommended uses
Blister cards for retail packs on folding boxboard and solid bleached board, sealed to thermoformed PVC or virgin PET blisters on platen heat-seal machines.
Substrates. Folding boxboard and solid bleached board for blister cards, sealing to thermoformed PVC and virgin PET blisters
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Water-based thermoplastic heat-seal dispersion | Formulation |
| Appearance | Milky liquid drying to a clear film | Visual assessment, supplier protocol |
| Carrier | Water | By formulation |
| Non-volatile content | 38 to 46 per cent by weight | ISO 3251 |
| Flow time, 4 mm flow cup at 20 degrees C | 30 to 45 seconds | ISO 2431 |
| pH at 20 degrees C | 8.0 to 9.0 | ISO 976 |
| Blister card bond, assessed as fibre tear on peel | Consistent fibre tear across the seal area | Peel assessment on the customer sealing tool, no single international method applies |
| Sealing window | Temperature, dwell and pressure established on the customer platen sealing machine for each board and blister combination | Customer or supplier protocol |
| Blocking of coated cards in the stack | No blocking at the agreed stack height and storage temperature | Customer or supplier protocol |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Flexo, gravure or offset coater applied over the printed card |
| Surface preparation | Board grammage, moisture content and print coverage under the seal area all change the bond; hold them constant between trial and production |
| Dilution | Supplied ready for use; adjust viscosity with 0 to 5 per cent water by weight |
| Applied dry coat weight | 5 to 9 g per square metre, by grammage difference to ISO 536, in one or two passes; the upper end of the window normally needs a second coating unit or pass on a sheet-fed coater |
| Drying | Hot air; cards fully dry and cooled to room temperature before stacking, as a warm heat-seal film blocks in the pile |
| Next step | Die cutting, then sealing to the blister on a platen heat-seal machine, with fibre tear on peel checked at start-up |
| Handling and safety | Refer to the Safety Data Sheet, issued by Arctic on request. |
Process. Flexo, gravure or offset coater applied, hot air drying, sealed on a platen heat-seal blister machine
6. Storage and handling
Store in the original closed container at 5 to 30 degrees C, protected from frost and direct heat, and stir gently before use. Shelf life is stated on the label and Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
