Packing:
1.Roll films are packed in vacuum plastic bag and heat-sealed with desiccants.
2.Bags are marked with ables 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 5~35º Cand 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:
≤10Ω/:6 months
10~15Ω/:3months
>15Ω/:1months
