<Example of drying conditions >
Drying under reduced pressure
Vacuum : Below 1,300 Pa (0.2 psi)
Temperature : 70 – 80 ℃ (158 – 176 °F)
Duration : 2 – 3 hoursHot-air drying
Temperature: 85 – 95 ℃ (185 – 203 °F)
Duration: 4 – 6 hours- LDPE Blown Film Extrusion (multi-layer)
Multi-layer film can reduce total amount of PELECTRON compared to single-layer film.
