Standard 25 kg laminated format for flour, sugar, and animal feed — PE or BOPP lamination for moisture protection and premium branded packaging.
The 45 × 80 cm laminated PP woven bag is the standard 25 kg packaging format across Canadian flour, sugar, and animal feed supply chains. This size balances handling ergonomics with production efficiency — heavy enough to minimize packaging cost per kilogram while remaining manageable for workers on packing lines, warehouse floors, and retail shelves. The lamination layer transforms the base woven fabric into a moisture-proof, printable package that meets food industry standards and brand presentation requirements.
Two lamination configurations are available for this size. PE inner lamination provides a continuous moisture vapour barrier for hygroscopic products such as flour, powdered sugar, and milk powder. BOPP outer lamination adds a high-gloss print surface for retail-grade graphics with photographic reproduction quality. Double lamination — PE inside and BOPP outside — combines moisture protection with premium brand presentation, and is the preferred specification for consumer-facing flour and specialty food products sold through grocery and food service channels across Canada.

Applications
The 45 × 80 cm format at 25 kg is the dominant packaging size in the Canadian flour milling industry. PE-laminated bags protect all-purpose, bread, pastry, and specialty flours from moisture absorption that causes caking and microbial growth. BOPP outer lamination enables the full-colour branded packaging that flour mills require for grocery and food service distribution. Double-laminated bags are the industry standard for retail flour brands.
Granulated sugar, icing sugar, and specialty sweeteners are packed at 25 kg for food service and industrial bakery customers. The PE moisture barrier is critical for sugar products that absorb humidity and solidify into hardened blocks during storage. The 45 × 80 cm format fits efficiently on standard pallets and is compatible with the automated filling and bag-closing equipment used in sugar refining and packing operations.
Feed manufacturers and pet food producers pack 25 kg bags for dealer and retail distribution in this laminated format. The PE barrier preserves freshness and prevents moisture-induced mould growth in nutritionally dense feed formulations. BOPP-laminated versions provide the high-impact shelf graphics required for branded pet food products competing in retail environments.
If your primary requirement is moisture protection, PE inner lamination is sufficient and cost-effective. If your primary requirement is premium print quality for retail branding, BOPP outer lamination provides the best graphics surface. If you need both moisture protection and retail-grade packaging, double lamination (PE inner + BOPP outer) is the recommended specification. Sackora can evaluate your product and distribution requirements to recommend the most cost-effective lamination configuration.
BOPP lamination provides a smooth, glossy surface that supports up to 8-colour rotogravure printing with photographic reproduction quality. Process colour (CMYK) and spot colours can be combined for full-colour product photography, detailed nutritional panels, and brand-accurate colour matching. The print quality on BOPP-laminated PP woven bags is comparable to flexible film packaging and significantly superior to printing directly on bare woven fabric.
Yes. The 45 × 80 cm format is one of the most widely used bag sizes in food and feed manufacturing, and is compatible with virtually all open-mouth filling equipment, bag-closing sewing heads, and heat-sealing systems. The dimensions also work with automated bag placers, conveyor checkweighers, and robotic palletizers commonly used in flour, sugar, and feed packing facilities.
