Mid-range gusseted format for 30–50 kg agricultural, fertilizer, and construction products — optimized for standard pallet patterns and automated filling.
The 50 × 85 cm gusseted PP woven bag is the workhorse format for mid-weight industrial and agricultural products packed at 30–50 kg. The 12 cm side gusset expands the bag from 50 cm flat width to 74 cm when filled, producing a stable rectangular package that fits standard 40 × 48 inch (1016 × 1219 mm) pallet patterns with minimal void space. The 80–100 GSM fabric weight is selected to handle the mechanical demands of automated filling, conveyor transport, and multi-layer pallet stacking without bag failure.
This size is the most commonly specified gusseted bag in Canadian fertilizer, soil amendment, and construction product supply chains. The dimensions accommodate standard 25 kg and 50 kg fill weights across a wide range of product bulk densities, from dense granular fertilizer to lighter expanded aggregates. Sackora manufactures this size with sewn top closure for open-mouth filling, with optional PE liner for moisture-sensitive products and UV stabilization for bags stored outdoors at distribution yards and retail locations.

Applications
The 50 × 85 cm gusseted bag is the standard packaging format for granular fertilizer, lime, gypsum, and blended soil amendments packed at 25–50 kg. The rectangular filled profile allows consistent 5-bag pallet layers on standard pallets, and the 80–100 GSM fabric withstands the abrasive nature of granular fertilizer products without premature wear or puncture during handling and stacking.
Dry-mix mortar, concrete repair compounds, grout, and sand are packed in this format for distribution to construction supply yards and job sites. The gusseted shape produces stackable units that resist shifting on pallets during truck transport. PE-lined options protect moisture-sensitive cementitious products from humidity during warehouse and outdoor storage.
Feed mills across Canada pack livestock feed, poultry rations, and whole grain in 30–50 kg gusseted bags for farm-direct and dealer distribution. The uniform cube shape maximizes truckload density on long-haul routes, and the open-mouth top is compatible with gravity and auger filling systems common in feed manufacturing plants.
Yes. The 50 × 85 cm format accommodates fill weights from 30 to 50 kg depending on product bulk density. For 25 kg products with lower bulk density, the same bag dimensions work well. For 50 kg fills of dense products like fertilizer, the 80–100 GSM fabric weight and 12 cm gusset provide adequate strength and volume. Sackora can recommend the optimal fabric weight for your specific product and fill weight.
Yes. The consistent rectangular profile produced by the side gusset is designed for robotic and semi-automated palletizing systems. The predictable package dimensions allow reliable layer pattern programming, and the flat bag faces provide stable gripping surfaces for vacuum and clamp-style palletizer heads.
For products stored outdoors for up to 6 months, Sackora recommends a minimum UV stabilization rating of 1600 hours (accelerated weathering). For longer outdoor exposure or high-UV environments, higher stabilization levels are available. UV-stabilized bags resist fabric degradation and colour fading caused by prolonged sunlight exposure at distribution yards and retail locations.
