1. Product description
A heat-seal lacquer for foil lids sealing to polystyrene and to rigid PVC containers, the pack types common in dairy, dessert and confectionery filling. It carries a higher film build than HS 110 to bridge flange irregularity on thermoformed styrenic pots. It is the styrenic and PVC grade of the HS family and is not interchangeable with the polyolefin or polyester grades.
2. Features
- Seals to polystyrene and rigid PVC containers
- Higher film build than HS 110 to bridge uneven thermoformed flanges
- Can be applied to the reverse face of lacquered or printed foil
- Not interchangeable with the polyolefin or polyester HS grades
3. Recommended uses
Lids for dairy, dessert and confectionery pots in polystyrene or rigid PVC, sealed on rotary cup fillers, form-fill-seal lines and tray sealers.
Substrates. Aluminium foil 25 to 50 micron; foil and paper laminate; lacquered or printed foil where the reverse face carries the seal.

| Sealing initiation temperature | 110 to 140 degrees Celsius | seals made to ASTM F2029, strength measured to ASTM F88 |
| Seal strength, web to web | 8 to 14 N per 15 mm, permanent seal, window agreed per pack | ASTM F88 |
| Adhesion of the cured lacquer | No removal on tape pull or after a bend over a mandrel; cross-cut classification 0 to 1 on foil laminate and on foil of 50 micron | in-house tape pull and mandrel bend on thin lidding gauges; ISO 2409 on foil laminate and on foil of 50 micron and above |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Roll coated on a web coating line, oven cured |
| Substrate and surface preparation | Aluminium foil 25 to 50 micron, foil and paper laminate, or lacquered or printed foil with the seal on the reverse face. Clean, dry, fully annealed foil; confirm the residual rolling oil level on incoming coils and prime with Arcfoil PR 110 where oil level, temper or a laminate face makes direct adhesion unreliable |
| Dilution | Supplied ready for use; if reduction is needed, use only the thinner specified by Arctic for the grade and recheck supply viscosity and solids |
| Applied dry coat weight | 5 to 8 g/m2, checked gravimetrically across the full web width |
| Cure | Peak metal temperature 160 to 190 degrees Celsius, measured with a travelling thermocouple on the web |
| Sealing conditions | Jaw 150 to 190 degrees Celsius, 0.2 to 0.4 MPa, dwell 0.5 to 1.5 s, set in the middle of the plateau found on the customer's filling line |
| Next step | Die cut and seal to polystyrene or rigid PVC containers only; confirm the container polymer before specification |
Process. Roll coated on a web coating line and oven cured; sealed on a rotary cup filler, form-fill-seal line or tray sealer.
6. Storage and handling
Store in the original containers, kept closed, in a cool, dry, covered area out of direct sunlight and within the temperature range given on the label. Shelf life is stated on the label and on the 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.
