Onions and potatoes are among the top products that are packaged for shipping; however, there are many unique requirements for storing these types of produce. When they are harvested from the field, they will continue to produce moisture and heat. If the moisture is allowed to accumulate within a sealed container (such as a plastic bag), condensation, mold growth, softening, sprouting and rapid spoilage may occur. Leno mesh bags help prevent these issues through their open weave design that allows air to flow freely throughout the bag. Singhal Industries Private Limited is a leading manufacturer and exporter of Leno mesh bags used for packaging onions and potatoes as well as providing food grade vegetable and fruit packaging alternatives. A Leno mesh bag supplier can offer you various options in terms of size, color, mesh size and weight capacity. While the bag does provide some assistance in preventing damage, it cannot solve all problems related to wet onions, damaged potatoes or inadequate storage environments. Breathable packaging is most effective when all aspects of the handling process support it.

Choosing the Right Size and Capacity

Onions and potatoes vary in their bulk density; therefore, the bag size should be based on both the product and how it will be filled. A 50-kg potato bag would not require the same dimension as a 25-kg onion bag. When products with low bulk densities are used, there is a greater requirement for space. To accommodate this need, either the width or height of the bag may have to be increased. Growers must provide their suppliers with the amount of product they want to package, the type of product, and the weight of the filled bags. They should also inquire about the dimensions of each size of bag offered. Singhal Industries' product description includes information regarding Leno Mesh Bags that can hold up to 50 kg of product and provide flexibility to maintain product freshness. Singhal Industries provides standard size options for these bags; however, custom sizes could potentially enhance filling speeds and pallet stability for large volume users. Large bags may bend or fall apart when stacked, whereas small bags may tear or rupture. This seems like an obvious issue; however, size mistakes are one of the primary reasons for packaging failures. The bag size selected should be for the mature product, not the seedling.

Mesh Type and Ventilation Needs

The size of the opening in the mesh determines how much air can flow into the bag (ventilation), how much of the contents are visible (visibility), and whether the contents will remain in the bag (retention). Diamond-shaped mesh is commonly used for both onions and potatoes, as it provides adequate airflow while allowing customers to see what's inside. Products such as garlic cloves or green peas may require a smaller mesh so they don't fall through. On the other hand, larger mesh provides greater airflow; however, it has less ability to contain products. Singhal Industries' product descriptions state that their Leno Mesh Bags feature a permeable design for freshness and can hold up to 50 kilograms. Additionally, because these bags are open, they allow for dispersion of ethylene gas, which is produced by many types of fruit and can accelerate the rate at which other produce rots. Prior to making a large purchase, request samples from your supplier to determine if the bags will function properly with your specific produce. It would also be beneficial to examine mesh size, airflow, strength, and durability. While a particular bag may be suitable for onions, it may not perform as effectively for smaller garlic or heavier potatoes. It is important to note that the product being placed within the bag ultimately dictates the type of mesh needed, not the catalog.

Strength, GSM, and Load Capacity

Strength of a leno mesh bag depends upon the quality of tape, how the fabric was constructed, the density of the weave, stitching, and seam design. Many times suppliers will refer to their bags by their weight per unit area (GSM) or by their maximum load-carrying ability (load capacity), i.e., 20kg, 25kg, 30kg, or 50kg. Typically, as GSM goes up, so does tape thickness, tear-resistance, and load-bearing capacity. For example, Singhal Industries' product descriptions state they produce 50kg load capacity leno mesh bags made with a strong leno fabric. Generally speaking, for heavy products such as potatoes and large amounts of onions, thicker fabric and/or reinforced stitching are desired. However, thicker fabric isn't always best. Thicker fabric can increase raw-material costs, add weight to the final product, and reduce the product's overall flexibility. The proper specifications for each application will provide the necessary strength to support the product during all phases of handling including loading, stacking, transportation-related vibrations, and unloading. A bag that weighs too much will result in wasted materials, while a bag that weighs too little will fail.

Moisture Control and Storage Conditions

The release of moisture by onions and potatoes while in storage, can lead to mold, sprouting, and/or decay if the moisture cannot escape. Leno Mesh Bags provide an escape route for moisture, through their permeable design that allows for air circulation to dry off the vegetables and reduce moisture levels. Singhal Industries products include Leno Mesh Bags that are described as being permeable for fresh produce and have a capacity of 50 kg. However, just because air circulates through the bag does not mean it will protect against temperature extremes. If the bag is left in a hot vehicle with no ventilation, then the produce will likely be damaged due to the high temperatures. Therefore, it is important to keep the filled bags in a cool, dry, and ventilated place. Sometimes the simplest solutions work best; however, the simple solution alone will not work unless there are other elements involved in the process (i.e., proper handling). Produce that has become wet should never be put into a bag immediately. Instead, allow the produce to dry completely prior to putting it into a bag. Also, remove any produce that appears damaged prior to storing the produce in a bag. While the bag itself helps protect the produce from excessive moisture, ultimately the environment in which the bag is stored determines whether or not the produce will remain fresh.

Custom Printing and Branding

Onion and potato producers often use branded packaging to sell their products at retail stores or to export them. Singhal Industries' product description states that their Leno Mesh Bags are suitable for food grade packaging of vegetables and fruits such as onions and potatoes. The mesh allows for airflow which extends the shelf life of the produce. However, because it is open mesh, the printing quality will not be as clear as if it were a solid film. Therefore, it is important to communicate with the supplier regarding your design options prior to ordering. Although a brightly colored bag may draw customers to the product, providing accurate information about the product is more beneficial. Before mass producing the bags, buyers should review the artwork and approve it. Incorrect printing of weight or origin information on thousands of bags can lead to expensive errors. Packaging should provide useful information about the product rather than simply being decorative.

Choosing a Reliable Leno mesh bag

Buyers need to look at materials, mesh uniformity, gsm (grams per square meter), dimensions, capacity, stitching, color, print, uv treatment, food safe, testing, production capacity and delivery reliability when selecting a Leno mesh bag exporter. Singhal Industries Pvt. Ltd., is a leading manufacturer and exporter of leno mesh bags, pp woven sacks, and other flexible packaging products from gujarat. Buyers should ask for samples and run tests using real onions/potatoes. Make sure to assess mesh size, airflow, strength, durability, and printing quality. Ask about minimum order quantities, lead times, certification, packaging, and replacement policies. Do not assume that a low cost means you will have the lowest total cost. If the bag rips, stretches, or has poor printing, then you could end up paying more in terms of lost product and negative customer feedback. A reliable supplier is as important as a reliable product.

Reuse, Sustainability

Leno Mesh Bags have several advantages; they are lightweight, compact prior to use, durable, reusable, and easy to manipulate. The mesh construction allows for free circulation of air which will help to decrease the amount of spoilage caused by trapped moisture. Also, due to the lightweight nature of the mesh bag, it can be transported with greater efficiency. If a bag remains intact and does not become dirty, then it can be used again to hold similar types of items. However, there are many rules regarding how bags must be handled to ensure that they meet all food safety regulations. Polypropylene can be recycled, however, this does not happen automatically.

Conclusion

When possible, individuals should collect any damaged bags and properly dispose of them. Overall, Leno Mesh Bags are an excellent option for packing both onions and potatoes. These bags allow for maximum airflow, visibility, durability, ease of use, and customization. It is important to select the appropriate bag for your needs, including the correct size, mesh, material, capacity, closure, and seam style. Additionally, working with a reputable manufacturer/exporter, testing samples of bags in actual conditions, and storing the bags appropriately will help to guarantee freshness.
