During peak harvest seasons and high-volume commodity transit in 2026, the structural integrity of packaging is the primary determinant of logistics velocity and cargo safety. SherkatTrade manufactures heavy-duty 50kg Woven Polypropylene (PP) Grain Sacks engineered specifically for high-capacity silos, flour milling complexes, and international grain trade corridors.
Produced at our state-of-the-art polymer textile complex in Isfahan, these sacks utilize 100% pure virgin polypropylene homopolymer resins without any regranulated fillers or calcium carbonate dilution. With an increased fabric GSM, dense weave geometry, and proprietary Anti-Slip surface texturing, our heavy-duty sacks allow silo managers and logistics operators to stack up to 25 layers vertically without shifting, buckling, or bursting, providing absolute protection against spillage and cargo degradation.
Every manufacturing lot is subjected to rigorous hydraulic burst, tensile elongation, and drop tests in accordance with ISO 21898 and ASTM D5034 standards:
Rough truck beds, shipping container walls, and forklift tines frequently rupture standard market sacks. SherkatTrade's heavy-duty virgin tapes absorb kinetic shock waves and dissipate shear stress, eliminating product loss.
The Anti-Slip texturing ensures stacks remain vertical and stable up to 6 meters in height. This dramatically reduces warehouse footprint costs and enhances workplace safety for logistics personnel.
Living grain grains naturally respire, generating internal moisture and heat. The engineered micro-porosity of our weave allows heat dissipation while preventing external particulate ingress, stopping mold growth and premature seed germination.
With strict dimensional tolerances under ±3 mm and ultrasonic heat-cut mouths that prevent thread fraying, these sacks feed flawlessly through automatic bagging and closing machines without downtime.
