The core design of this ventilated ton bag lies in its special woven structure, with an air permeability of ≥30%, which allows air to circulate freely, effectively discharging water vapor and carbon dioxide generated by grains, biomass particles and other materials during storage, avoiding mold, deterioration or caking of materials. Compared with closed ton bags, it does not need to be equipped with an exhaust valve, reducing production costs and air leakage risks. It is made of standard polypropylene woven fabric with a thickness of 0.7mm, with good tear resistance and load-bearing capacity, with a rated load capacity of up to 800kg to 1000kg. The cross-shaped lifting loops can evenly disperse the load, which can safely adapt to forklifts and crane hoisting operations. Since there is no airtight inner membrane, it is lighter in weight, easy to recycle and fold for storage, reducing transportation and storage costs, conforming to the industry trend of green packaging. It has passed ISO 9001 quality management system certification, with stable and reliable product quality.
This ventilated ton bag offers two rated load specifications: 800kg and 1000kg, with a standard size of 85cm (length) * 85cm (width) * 110cm (height), and custom sizes are available. The woven fabric is made of polypropylene raw material, treated with a special weaving process, with an air permeability of ≥30%, which ensures air circulation without causing material leakage. The breaking strength is ≥22kN/m, with excellent tear resistance, which can withstand friction and impact during daily loading and transportation. The lifting loops are made of high-strength polyester webbing with a breaking tension of ≥70kN, which can safely adapt to 10-ton hoisting equipment. The sealing part adopts the design of top sewing plus bottom discharge port, and the sewing thread is made of high-strength nylon thread with a tensile strength of ≥10kN, ensuring the sealing during loading. The product weighs about 1.2kg each, which is easy to handle and store, and the folded volume is only 1/10 of the original volume, greatly reducing storage and transportation costs.
It is mainly applicable to grain storage enterprises, biomass energy production plants, organic fertilizer processing plants, feed production workshops and other scenarios, and can be used for transporting and storing bulk materials that need ventilation such as wheat, corn, soybean, wood chips, organic compound fertilizer. During outdoor storage and long-distance sea transportation, it can effectively avoid mold and caking of materials caused by airtightness, extending the shelf life of materials. At the same time, it can also be used for transporting gardening supplies, pet feed and other materials that need ventilation, and is more cost-effective than traditional closed ton bags, suitable for small and medium-sized enterprises and individual merchants.
