II. Packing, Mark, Preservation and Transportation
1. The film should be provided in rolls and wound up to the pipe core, each roll is well packed and loaded with plastic bag to be placed into dry and clean box.
2. Each box packing should be marked with the type, product specification, size, lot number, gross weight, date of manufacture, name of the manufacture and the product acceptances certificate is attached. At the same the painting words of “Dampproof”, “collision-proof” etc. Should be marked.
3. The film should be preserved in dry and clean room. The preservation period from the date of period is two years and can still be used when it is qualified in case of the preservation production is exceeded and checked according to standard.
4. During the preservation and transportation, damping and mechanical damage should be avoided.
