In addition to regular type of PP for stationery market, our R&amp;D team is strong in developing new technique and formulations that cater for specific market needs. Our  Crystal Clear PP &nbsp;(BPP) of which we developed for cosmetic packaging is a good example. Because of its super high transparency as well as anti-scratch property, has made it an indispensible replacement for PET. Our  High Frequency Compatible PP  (HFPP) was developed for a mass ring binder maker in US who had to give up using PVC because of environmental reason. Our HFPP, because of its co-weldability property with high frequency welding, has made it a super alternative option from PVC.........
