n 包装Packing
|
Ø 膜卷用塑料袋包装，抽真空后放入干燥剂热封 Ø 塑料包装袋外贴标签标明型号，厚度，宽度，留边宽度和电阻 |
Ø Roll films are packed in vacuum plastic bag and heat-sealed with desiccants. Ø Bags are marked with lables of types , thickness, Ø width, free margin width and resistance. |
|
Ø 塑料袋外面用纸箱包装 Ø 纸箱外面用木箱包装或者加固纸箱 |
Ø The bags are packed in carton cases. Ø The cartons are wrapped in wooden cases or reinforced carton. |
n 储存Storge
|
Ø 金属化膜在使用之前应该按原包装保存。环境温度应该控制在5～35℃，湿度小于85%RH。 Ø 金属层暴露在潮气中会很容易发生氧化。因此，包装打开后，膜卷应该尽快使用。 Ø 建议打开包装的膜卷应该保存的温度条件是15～25℃，湿度小于60%RH。 Ø 金属化膜若保持原密封包装，并储存在如上所述的环境下，那么其储存期限可以满足下列条件： 铝金属化薄膜：从交付日起12个月。 锌铝金属化薄膜：因为锌相当不稳定，储存的期限取决薄膜的电阻： 小于等于10 Ohms：6个月（从交付日起） 10 Ohms到15 Ohms：3个月（从交付日起） 15 Ohms以上：1个月（从交付日起） |
Ø metallized film should be stored in its original package until its use with temperature 5 ～ 35℃ and humidity less than 85%RH. Ø metallized layer is easily oxidized when exposure to moisture. Therefore, the film should be used as soon as possible when opened.
Ø The recommended temperature is 15 -25℃ with humidity less than 60%RH after the package is open.
Ø 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 depends on the resistance of the film: Less than 10 Ohms: 6 months (from delivery date)
10 Ohms to 15 Ohms: 3 months (from delivery date)
15 Ohms: 1months (from delivery date) |
