Where the article reads:

"MFI (Melt Flow Index) identifies the flow speed of the raw material in the process. It helps to fill the plastic mold during the production process. The higher MFI increases, the weaker the raw material gets."

Perhaps it should read "MFI (Melt Flow Index) identifies the flow speed of the raw material in a stadard test; the MFI is an indicator of the effectiveness with which the raw material will fill a mould. Higher values of MFI indicate quicker mold filling but are generally associated with a weaker final product."

This sentence needs to be rewritten "It also has Copolymer and Random Copolymer. Copolymer helps stiffness of the PP (Polypropylene). Random Copolymer helps transparent look."

Instead of "Copolymer is more expensive than Homopolypropylene. Random Copolymer is even higher than copolymer PP." consider "Currently the Copolymer form is more expensive than the Homopolypropylene form with the random Copolymer form being the most expensive." - well something like that.
