Packing:
1. Roll films are packed in vacuum plastic bag and heat-sealed with desiccants.
2.Bags are marked with lables of types
3. The bags are packed in carton cases.
4.The cartons are wrapped in wooden cases or reinforced carton.
Storge:
1. Metallized film should be stored in its original package until its use with temperature 5 ~ 35ºC and humidity less than 85%RH.
2. Metallized layer is easily oxidized when exposure to moisture. Therefore, the film should be used as soon as possible when opened.
3.The recommended temperature is 15 -25ºC with humidity less than 60%RH after the package is open.
4.With original sealed package, and stored in the above mentioned conditions, the storage time can be as following:
Al metalized Film: 12 months from the delivered date..
Al/Zn Alloy metalized Film: As Zn is relatively unstable, preservation period(from delivery date) depends on the resistance of the film:
≤10 Ω/: 6 months
10 ~15Ω/: 3 months
>15Ω/: 1months
