HANDLING PRECAUTIONS
Coating weight (g/m²) | ≥3.5 | ||
Working concentration (%) | 25-35 | ||
3 stages drying from inlet to outlet(℃) | 50-60 | 60-70 | 70-80 |
Laminating temperature(℃) | 50-90 | 50~60 (esp. for films susceptible to temperature) | |
Laminating pressure | Under the circumstances of not damaging the films, the pressure should be increased to a feasible extent. | ||
Curing temperature(℃) | 50±5 | ||
Curing time(h) | ≥72h; ≥96h for the best. (At least 24h of curing to the pre-laminated films is required before the completion of rewinding or laminating of 3 layer composite film. And It is needed to preform the process of pouch making after the completion of curing perfectly.) May consult our technical support for more details. | ||
