THE PP RIGID FILM USEAGE Polypropylene (PP) has three configurations: isotactic, random and syndiotactic, HomopolymerPPand CopolymerizationPP(including Random、block copolymerization),Collectively referred to as polypropylene resin,The output accounts for about 15% of the total plastic. 01 Homopolymer PP Good impact resistance and creep resistance,can reach the grade of food. Mainly used for food packing. 02 Copolymer PP Good rigidity,Poor impact resistance,Intolerant to low temperature,Generally semi-transparent,used for woven bags,cheap raw materials.
