50kg capacity heavy-duty woven polypropylene bag with sewn-top closure, built for the most demanding construction and industrial packaging requirements.
The 55×100 cm open mouth PP woven bag is the largest standard size in the open-mouth format, purpose-built for 50 kg fill weights in the construction, mining, and heavy industrial sectors. At 90–120 GSM, the fabric is the heaviest in the open-mouth range, delivering the tensile and burst strength required for dense materials like Portland cement, sand, dry morite mix, and industrial-grade aggregates. This bag replaces multi-wall paper sacks in applications where moisture exposure and rough handling would compromise paper packaging.
Across Canada, this size is the standard for bagged cement and construction sand sold through building supply dealers, hardware chains, and direct to contractors. The bag is frequently specified with UV stabilization because construction materials are routinely stored on outdoor job sites and retail yards. The open-mouth closure supports high-speed filling at cement plants and dry-mix facilities, and the sewn top provides a robust seal that withstands the stacking pressures of palletized storage — typically 40–50 bags per pallet in a cross-hatch pattern.

Applications
The 55×100 cm bag is the industry-standard format for 50 kg bags of Portland cement, mortar mix, grout, and stucco across Canadian construction markets. The heavy-duty 90–120 GSM fabric withstands the high density and alkalinity of cement products, while PE lamination prevents moisture ingress that causes premature hardening during storage.
Building supply retailers and contractors rely on this bag size for bagged sand, gravel, and decorative stone. The woven polypropylene construction handles the extreme weight and abrasiveness of mineral aggregates without the tearing issues common with paper sacks. UV stabilization is essential for bags stored in outdoor retail yards and on construction sites.
Mining operations and industrial manufacturers use this maximum-capacity format for mineral concentrates and powders, calcium chloride, rock salt, and other dense industrial materials. The 50 kg fill weight maximizes throughput per bag while staying within standard manual handling and palletization equipment capacities used across industrial facilities.

Many of our customers in the cement and construction sectors are transitioning to mechanical handling (forklifts, conveyors) for palletized 50 kg bags. We can also produce this bag in a 40 kg configuration if your operation requires lower manual handling weights while maintaining the same bag dimensions.
Woven polypropylene dramatically outperforms multi-wall paper in moisture resistance, tear strength, and outdoor durability. Paper cement sacks absorb moisture and lose structural integrity when exposed to rain or ground contact — a common scenario on construction sites. PP woven bags maintain their strength in wet conditions and resist the alkaline chemistry of cement that accelerates paper degradation. The result is significantly lower bag failure rates and reduced product waste.
For bags that will be stored outdoors for up to 3 months — typical for construction site and retail yard conditions in Canada — we recommend standard UV stabilization. For extended outdoor exposure beyond 3 months, a higher UV additive concentration is available. We assess the appropriate level based on your geographic region, expected storage duration, and whether bags will be covered or fully exposed.
