Jumbo Bag
Product Details
The Jumbo Bag (flexible bulk container) is a specialized type of flexible bulk container designed for the transportation and storage of bulk powdered, granular, or lumpy materials. It is widely used in industries such as chemicals, food, and mining.
Definition and Core Purpose
Basic Definition: Large-volume foldable packaging bags made of materials such as polypropylene (PP), designed for mechanical loading and unloading via top or side lifting to enhance logistics efficiency.
– Core Purpose: To protect materials from moisture and contamination, suitable for bulk goods requiring batch transportation, such as chemical raw materials, grains, and mineral products.
Specifications and Load Capacity Standards
1. Size range:
– Common dimensions: 94cm×94cm×122cm (approximately 37 inches×37 inches×48 inches).
– Capacity: Approximately 2,200 liters (suitable for 1 ton of material).
2. Load-bearing capacity:
– Safe Working Load (SWL): 500–1500 kg/bag, with 1000 kg (1 ton) being the mainstream.
– Safety factor: 5:1 or 6:1 (i.e., the load capacity is 5–6 times the design load).
3. Classification:
– By shape: Cylindrical, square, conical (suitable for viscous materials).
By Structure: Four-ring Lifting (Standard Type), Tunnel Ring (Forklift Loading/Unloading), Ventilation Type (Fruit and Vegetable Preservation).
Industry Applications and Logistics Scenarios
Chemical industry: accounts for 40–50%, transporting PVC resin, carbon black, etc., requiring pollution prevention design.
2. Grain and Agriculture: Used for grains, feed, and fertilizers, ventilated bags maintain material dryness.
3. Mineral Resources and Building Materials: Cement and aggregate transportation, requiring high load-bearing capacity (e.g., specialized ore bags).
4. Special Scenarios:
Container Liner: Designed for 20–40-foot containers, moisture-resistant and suitable for maritime transportation.
– Food-grade certification: Required for sugar, flour, etc., with dust-free processing.
