which we manufacture make small surface peculiar resistance of a film or a bag, as shown in a lower table. The more surface peculiar resistance becomes small, the more dust stops being able to adhere easily. The numerical value of surface peculiar resistance changes with environment, such as humidity and temperature. Therefore, although the value of the following table is not a guarantee value, it turns out that it has the effect that our electrification prevention processing and conductive ability processing can control static electricity as compared with the usual goods. Electrification prevention processing is indispensable to the film and polyethylene bag which are used inside a clean room. If dust has adhered to the packing materials carried in from the outside, the performance of the clean room itself will become bad. Moreover, electronic products, home electronics, precision apparatus , etc. are very sensitive to static
electricity, and uncongenial to the plastic bag and film which are
originally easy to be electrified. In a clean room, the film which prevents the electrification prevention plastic bag and static electricity of our company plays an active part. For example, in case an electrification prevention plastic bag is carried into a clean room, only by blowing air, the dust of the surface in a bag is removed and the degree of cleanness can be maintained. Moreover, we are also dealing with the plastic bag for clean rooms of a severe standard. The vacuum plastic bag for clean rooms which used additive-free polyethylene is treated.
