Packing of Metallized Film
1.The piled rolls are packed in plastic bad abd heat-sealed with esiccants after vacuum removals
2.Labels inside the bages mark film class,type,thickness,width,free margin width and resistance
3.The bags are packed in carton cases
4.The carton cases are packed in wooden cases or reinforced carton
Storage of Metallized Film
1.Metalized film should be stored in its original packing until use.The temperature should be controlled to 5-35 oC and humidity less than 85% RH.
2.On exposure to moisture,the thin metalized layer is likely to be easily oxidized.Therefore,after the packing is opened,the rolls should be used as soon as possible.
3.It is recommended that the opened rolls be stored in temperature conditions of 15-25 oC
4.Metalized film kept sealed in the original packing and stored as described above is guaranteed according to the following conditions
5.Al metalized film:12 months from the delivered date
6.Al/Zn Alloy metalized film:As Zn is relatively unstable,preservation period depends on the resistance of the film
7.10 Ohms or less 6 months(from delivery date)
8.10 to 15 Ohms 3 months(from delivery date)
