Since Metal Mellapak was be developed & accepted by market, Scientists find Metal Corrugated plate packing was not suitable in any medium’s requirement. If adopting Metal material, it is difficult to universally use in industry. Plastic plate packing was appeared.. Compared with Metal Corrugated plate packing, it has large flux, low pressure drop,high surface area and so on. In addition, owing to this packing is placed side by side inside the column with subsequent layers rotated at 90℃, the solid will be discharged from the packing’s bottom & opening.so its Anti-clogging ability greatly enhanced.Therefore, it was widley apply in gas purification, fertilizer, environmental protection, metallurgy and other industries
