Bags are marked with type labels, mark thickness width, free margin
width and resistance.The bags are packed in carton cases.The
cartons are wrapped by wooden cases or
reinforced carton.Storage:Metallized film should be stored in its
original package with temperature 5 - 35ºC and humidity
less than 85%RH before using.Metallized layer is easily
oxidized when exposure to moisture. Therefore, the film should be
used as soon as possible when opened. The recommended
temperature is 15 -25ºC with humidity less than
60%RH after openingWith original sealed package, and stored as
mentioned above, the storage time can be as following: Al
metallized film: 12 months from the delivery date. Al/Zn Alloy
metallized film: As zinc is quite unstable , the storage period
(from delivery date) depends on the resistance of the film:≤10
Ω/square: 6 months 10 ~30Ω/square: 3 months >30Ω/square: 1month
FAQ: Ask: Which type of the metallized capacitor film your factory
producing ?Reply: Metallized polypropylene film &
Metallised polyester film for capacitor use.Ask: What are the
thickness you are producing ?Reply: Metallized polypropylene film
from 2um to12um. Metallized
polyester film from 1.9um-12umAsk: If your factory could
produce the wave cut metallized film ?Reply: Yes, we could be
according to your requirement to wave cut.Ask: For the
metallized capacitor film are very easy oxidation, how do you
protect the film and transport them safty to our factory
? Reply: For our packing is as follows:1.Roll films are
packed in vacuum plastic bag and heat-sealed with desiccants.2.Bags
are marked with labels of types.3.The bags are packed in
carton cases.4. The cartons are wrapped in wooden cases or
reinforced carton. 5. If the goods are bad of
packing problems,we will Indemnify the goods.Ask: what is the
quantity for one 20ft container loading?Reply: usually 6-7tons.
(details according to your specification) Ask: What is the
delivery time ?Reply: 5-10days after you placing the order.
