Before placing a large order for bulk bags, obtaining and inspecting a sample is highly recommended. Custom Bulk Bags prides itself on exceptional customer service and the world-class quality of its products, so we suggest that our customers request a sample of the products before committing to an order.

This not only ensures that you get the exact specifications needed, or gives you an opportunity to make slight changes to the design, but it also holds benefits for us as the manufacturer and supplier. Incorrect specs can be a waste of resources and manufacturing time, so we like to make sure that our customers receive usable products that meet their every need.

We produce up to 3.5 million bulk bags per annum for a wide variety of customers, including various mining companies and ore processors. All of our bulk bags have a minimum safety factor rating of 5:1 and are manufactured in accordance with international regulations and standards.

Custom Bulk Bags seamstress sewing a bulk bag

Samples reveal where specs may be incorrect

Putting your specs down on paper does not always mean that they will be perfect for your needs. Some minor details can be left out, which could have an impact on the usability of your bulk bags. Incorrect specs will also carry a cost implication and time delay on a large order.

For example, you may require a sift-proof seam on your bags, so this forms part of your specs. However, there are a few ways to create a sift-proof seam, depending on the materials you’re storing and our manufacturing equipment. This could change the price of the final bag slightly.

By receiving and inspecting a sample before placing a bulk order, you’ll be able to see whether the bulk bag is suited to your needs and the task at hand. By filling this sample bag with your material, you’ll be able to see whether it works as intended and if it fits your equipment properly. It’ll allow you to be certain of the dimensions and specs for the rest of the order.

Why a bulk bag supplier may need access to your business

Ask for samples when changing supplier

This may seem like an obvious decision when working with a new packaging supplier, but there are some important details to consider. Not all bulk bag manufacturers and suppliers use the same terminology – some components have different names, even bulk bags can be called flexible intermediate bulk containers (FIBCs) or jumbo bags by other suppliers.

This means that you may know certain optional extras by a different name. When switching to a new supplier, asking for a sample will give you a real look at the final product and all of the optional extras requested. If anything is missing, you’ll be able to correct it before the bags enter mass production.

Obtaining samples makes the entire process more cost-effective and efficient for you and the manufacturer. It will allow you to ask any further questions to your supplier and iron out any configuration or construction changes before placing the bulk order. Lastly, a sample will give you a far more accurate quote as every minor detail will be agreed upon before the order is placed.
