包裝
由于有機物的吸收,在一般室內環(huán)境中長時間(幾個月)存放的膜通常會變暗/變褐色。在儲存期間,應確認產(chǎn)品是否保持密封。
· 保持膜密封并防止一般暴露,可減少有機物的影響。長期儲存時,建議使用密封袋存放。
· 變色不影響性能,使用稀硝酸浸泡可除去顏色。

Darkening/browning is common for pieces stored in a general room environment for an extended period of time (several months), due to organics pick-up. Verify product is kept sealed during storage.
Keep pieces sealed and protected from general exposure will reduce the effect. Recommend long term storage in air-tight bags.
Discoloration does not affect performance and can be removed by soaking in dilute nitric acid.
Packaged in heat-sealed foil bag in stay-flat mailers
