PP (polypropylene) woven bag is the standard food-grade bulk packaging for Pakistani spice, seed, salt and grain exports — typically 25 kg or 50 kg with optional inner liner for moisture barrier.
A PP woven bag is a sack manufactured by weaving polypropylene tapes (slit film) on a circular or flat loom into a tight cloth, then cutting and stitching it into bag form. PP woven bags are strong, lightweight, water-resistant, food-grade-safe (when made from virgin PP without recycled content), and economical — making them the workhorse bulk packaging for agricultural exports across South Asia.
Standard weights for Pakistani spice, seed and salt exports are 25 kg and 50 kg. Common construction options:
For Pakistani exporters, PP woven bags hit the right balance of cost, food-grade compliance and shipping robustness:
For premium / retail private-label, exporters move up to BOPP-laminated PP with full-colour printing; for bulk pharma/nutraceutical raw material, the move is to inner PE liner with heat seal for moisture and microbial barrier.
