Cement, Chalk and flour Sack
carriage and storage of cement, gypsum and flour
This product is a woven polypropylene suck for cement, gypsum and flour.
Nanoparticles due to a large surface area to volume ratio and high surface energy, as fillers in polymeric matrix, improve the strength and modulus.
According to INSO 2972 (Packaging-woven polyolefin sacks – Specification and test method), mechanical properties of the product improves by adding nanoparticles into it. See the following table
Polypropylene woven sucks should possess good mechanical features like high tensile strength and elongation to be useful in maintenance and transportation of the cement, gypsum and flour. Theses sucks could be produced by polypropylene strips which its production process has been improved by adding nanoparticles.
