Film should be wrapped in a tube on core and supply in rolls; Each volume in a plastic bag packing and seal, placing in dry and clean case 2. Each box packaging should specify model or type, product name, specification, batch number, gross weight, net weight, manufacturing date, manufacture ¡¥s name, and product test report. At the same time, marked "Moisture proof" "Prevent Impact" and other words in packing body. 3.Film should be stored in a dry and clean indoor, from the date of original shipment, shelf life for two years, more than storage life according to the standard check again, qualified can still use. 4. In storage and transport process, should avoid damp and mechanical damage.

The most outstanding characteristics of Polyimide film is for its high temperature endurance and insulation ability. To make a polyimide film, first form the film by condensing pyromellitic dianhydride(PMDA)and Diamino diphenyl ether(DDE) in strong solvents, and then be treated by imine at a high temperature It exhibit excellent thermal resistance, high insulation resistance, engineering properties, chemical stability, radiation resistance, inflammability and fire resistance rated at 94V-0. The product is halogen-free, and meets the environmental protection standard for its heavy metal and other restricted organic materials. Electronic parts, mechanic components, insulation on electrics, insulation tube, composite insulators.
