包装
由于有机物的吸收，在一般室内环境中长时间（几个月）存放的膜通常会变暗/变褐色。在储存期间，应确认产品是否保持密封。
· 保持膜密封并防止一般暴露，可减少有机物的影响。长期储存时，建议使用密封袋存放。
· 变色不影响性能，使用稀硝酸浸泡可除去颜色。

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.
