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.
