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) | 24-48h (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. | ||
