In addition, the wet season is also prone cardboard, and India is not clear, the plane dust, out of paper deformities, bring toilet paper, Antistatic bosses chemical handling or processing technology standard is not high, electrostatic adsorption, there is more feed Zhang, especially when dry weather.
