40kg capacity woven polypropylene bag with sewn-top closure, engineered for heavy-duty industrial and agricultural packaging applications.
The 50×85 cm open mouth PP woven bag is a heavy-duty format designed for products in the 35–40 kg fill weight range. It serves the fertilizer, mining, and chemical industries where product density and abrasiveness demand a stronger fabric construction. The 80–100 GSM specification provides substantially higher tear and puncture resistance than standard food-grade bags, making this size the workhorse for granular and powdered industrial products across Canada.
This bag is commonly specified by fertilizer blending plants, mineral processors, and chemical distributors who need a reliable, cost-effective alternative to multi-wall paper sacks. The woven polypropylene construction offers superior moisture resistance and shelf life compared to paper, with significantly lower failure rates during palletized storage and transport. For products stored outdoors, UV-stabilized fabric prevents degradation from prolonged sun exposure — a critical feature for fertilizer warehoused at agricultural dealerships and co-ops.

Applications
The 50×85 cm bag is a standard format for granular fertilizer, potash, urea, and blended soil amendments sold in 40 kg bags. The 80–100 GSM fabric handles the density and abrasive texture of fertilizer granules, while UV stabilization protects bags stored in outdoor agricultural retail environments.
Mining and mineral processing operations use this bag for calcium carbonate, silica, bentonite, and other powdered or granular mineral products. PE inner lamination prevents moisture contamination in hygroscopic minerals, while the heavy-duty fabric resists puncture from sharp mineral particles during filling and handling.
Chemical distributors and manufacturers specify this size for dry chemical compounds, resins, and industrial powders. The closed-weave polypropylene fabric provides dust containment during transport, and optional inner liners add an additional barrier for products that require isolation from the outer packaging material.

View Specs →Woven polypropylene provides superior moisture resistance, higher puncture and tear strength, and longer outdoor storage life compared to multi-wall paper. PP woven bags also have significantly lower failure rates during palletized transport — reducing product loss, cleanup costs, and liability. For fertilizer and mineral products that may be stored outdoors, the difference in durability is substantial.
If your bags will be stored or displayed outdoors for any period — which is common for fertilizer at agricultural dealerships and mineral products at construction sites — UV stabilization is strongly recommended. Without it, polypropylene fabric degrades under prolonged UV exposure, reducing tear strength and bag life. We can specify the appropriate UV additive level based on your expected outdoor exposure duration.
Yes. The 80–100 GSM fabric weight used in the 50×85 cm bag provides the thickness needed to resist abrasion from granular fertilizer, mineral aggregates, and other sharp-edged products. For highly abrasive materials, we can specify fabric at the upper end of the GSM range or add a PE inner coating that provides an additional protective layer between the product and the woven fabric.
