Custom Ventilated Bulk Bags for Potatoes and Onions: A Buyer’s Checklist

Purchasing ventilated bulk bags is not just about choosing the size of the bag and adding ventilation boards. The bag must match the product, filling line, lifting equipment, and unloading method, while also considering storage and transportation conditions.

A useful starting point for potato packers, onion exporters, agricultural cooperatives, and packaging distributors is to describe the work that packaging bags need to complete. Is it used for transporting agricultural products between facilities, storing a batch of products before packaging, or to support export transportation? This guide translates these requirements into a customized consultation checklist.

The function of breathable bulk bags - and the functions they do not have

Breathable container bags use breathable parts or open fabric structures to promote air exchange. When air permeability is included in the processing requirements, they are used for transporting agricultural products such as potatoes and onions.

However, bulk bags with good breathability cannot replace storage and transportation solutions. Choosing only breathable design does not guarantee suitable temperature, humidity, or production conditions, nor does it guarantee that the goods will not condense or deteriorate.

When comparing suppliers, ask how the proposed design supports your process flow. Avoid choosing a bag based solely on claims such as "maximum airflow" without a clear structure and evaluation method.

Starting from the product and route

Describe potatoes and onions as separate application scenarios, rather than assuming that one specification applies to both. Including product size range, packaging condition, expected loading weight, and any related handling precautions.

Then plan the route: loading, temporary storage, loading, transportation, and unloading. Pay attention to where the bags will be stored, how long each stage will last, and whether the agricultural products will be repackaged later.

If the reason for changing the packaging is a recurring issue, please describe where the problem occurred. Photos of bags filled with products, opening or unloading processes can help suppliers distinguish between bag design issues and broader handling issues.

Confirm ventilation construction

The breathable bulk bag used for storing potatoes and onions can adopt different breathable fabrics and ventilation part layouts. Please ask the supplier to clearly specify the proposed structure, including the location and scope of these parts.

Before approval, let's discuss three questions:

Has the fabric arrangement retained the smallest product in the batch?

Is it suitable for placing bags during storage and transportation?

How to evaluate the suitability of ventilation in expected operations?

A more open structure does not necessarily mean higher specifications. Production sealing, fabric durability, and ventilation must be considered simultaneously. If it is recommended to use lining or coating, inquire about its impact on ventilation requirements.

Simultaneously specify bag size and loading requirements

Please specify the required bag size and expected weight of the agricultural product. Merely describing it as a 'one ton bag' is not sufficient to determine the size, usable capacity, or allowable carrying weight of the proposed bag.

If you need to replace the existing bag, please provide its specifications and specify which parts must remain compatible: loading frame, tray arrangement, storage location, or receiving equipment. If the required size is unknown, please provide the supplier with the loading weight target and available process information for review of the proposed size.

Before placing an order, please confirm the stated safe working load, applicable design, and relevant supporting documents. Do not use the physical volume of the packaging bag as evidence that it can safely carry specific loads.

Match the opening with filling and unloading

Select the top and bottom areas around the device, as well as the method of handling the product.

Please provide a drawing showing the opening size and closure device. Evaluate the unloading process together with the receiving team, including whether the process is controlled and acceptable for the product.

Check the compatibility between lifting and placement

Inform the supplier on how to lift and transport the bags. This includes the required equipment, relevant forklift or accessory dimensions, and any existing lifting devices that must be matched.

Follow the manufacturer's operating instructions and use appropriate equipment and procedures. Don't assume that rings with similar appearances mean that two bags can be handled in the same way.

If stacking bags is required, please seek specific guidance on the intended bags, contents, and placement conditions. Confirm the loading plan, rather than inferring its stackability based solely on photos of the product.

Your customized breathable bag inquiry list

Please attach existing bag drawings or clear photos as much as possible. Separate basic requirements from preferences so that suppliers can clarify which details need to be clarified.

Confirm the sample for pre production review

Agree on sample specifications and approved standards before ordering production batches. Check the dimensions, fabric structure, openings, closures, and lifting compatibility against the drawings.

Then, use representative products and appropriate processing procedures to review the samples during the expected process. Record the results of filling and unloading, generate retention, and any relevant observations during storage or transportation evaluation.

Merely conducting satisfactory fitting checks cannot determine the storage performance of a product. Agree with the relevant team on the evidence required for your specific use and retain approved specifications and sample references for future repeat orders.
