1）Package

Packages should be ventilated and damp-proof. Light-colour zippers will change colour if packed in PVC bags for a long time.

2）Storage

Store them in a ventilate atmosphere and avoid from direct exposure in air and sunshine. Avoid high concentration of gases H2 S and Cl2 in storage, otherwise they will turn black.

3）Transportation

Please inform our technical staff of your shipping preferences as the high temperature, high moisture and high salinity content in marine transportation will easily corrode metal parts on zippers or metal teeth. A salt-spray test is required for zippers in marine transportation.
