Packing and Transportation

1)The inner and outer package depends on the dimension and quantity of purchase order. Normally, the product is protected with

PE bags and other inner package, then placed in cartons for transportation.

2)Handle with care during transportation, and try to avoid violent collision or vibration.

Cautions

1) Store the product away from direct sunlight, heat and dust.

2)The product must be kept in a sealed package, stored in an environment with temperature of 23±5°C and relative humidity of 30-

70%. Before opening the package, pre-condition the membrane roll to the processing area temperature for 24 hours.It should be

used as soon as possible once the carton is opened.

3)Once opened and exposed to the environment, the membrane will equilibrate to the ambient relative humidity, and change in

dimensions accordingly. Membrane with customized dimension should be measured at 23°C and 50% RH.
