Application Process
- Designed for dry lamination and requires a laminating machine equipped with a drying tunnel and heated laminating rollers.
- Recommended operating parameters:
– Drying tunnel temperature: 60–95°C
– Laminating roller temperature: 60–80°C
– Laminating pressure: 8–20 kg/cm² - When conditions allow, it is recommended to dry the adhesive to 70%–90% before lamination, because:
– It achieves higher gloss in the laminated product
– It supports higher running speeds
– The laminating roller temperature should be reduced below 50°C to prevent bubbling
– The pressure should also be slightly reduced to avoid adhesive extrusion
Precautions
When using a fully dried adhesive process, increase the laminating roller temperature and pressure appropriately (without damaging the film) to ensure optimal bonding strength and surface quality.
