Sant Julia de Loria purchases of What is the load-bearing capacity of Kraft paper packaging bags?

The load-bearing capacity of Kraft paper packaging bags is based on the material thickness and structural design. The conventional model can bear 5-20kg, and the thickened model can bear up to 50kg.

The load-bearing capacity of Kraft paper packaging bags depends primarily on the paper's thickness (measured in grams per square meter or GSM), ply structure, and handle or bottom reinforcement.
Capacity by Paper Weight (GSM) and Design
• 60–70 g/m²: Ideal for lightweight items like clothing or baked goods, typically holding 2 to 3 kg (up to about 5 lbs for single-layer designs).
• 80–90 g/m²: Suitable for heavier retail products like books or small boxes, typically holding up to 5 kg.
• 100–120 g/m²: Designed for bulkier items like bottled goods or heavy retail purchases, holding between 8 and 10 kg (double-layer or laminated options often support 8–10 kg or 17–22 lbs).
• Over 120 g/m² & Multi-Wall Sacks (2–4 plies): Used for industrial applications, bulk goods, or heavy materials like cement and agriculture produce, easily supporting 15 kg to over 25–50 kg depending on ply construction and reinforcement.
Key Factors Affecting Strength
• Ply Count: Single-ply bags handle light retail goods, whereas multi-wall construction (2 to 4 layers) drastically increases Sant Julia de Loria Tea quotationTear and rupture resistance for heavy items.
• Material Type: Virgin Kraft paper features longer, interlocked wood fibers, offering higher tensile and bursting strength than recycled-fiber blends.
• Environmental Conditions: Moisture significantly weakens paper structure unless the bags include wet-strength resins, wax coatings, or plastic/foil laminations.
