When it comes to packaging bulk quantities of material, businesses commonly have a couple of choices; corrugated cardboard or polypropylene bulk bags (also called flexible intermediate bulk containers, or FIBCs). Recently, the cost of cardboard has increased worldwide due to disruptions in the supply chain. The price of bulk bags, however, has remained constant – especially when coming from a local manufacturer or supplier.

Custom Bulk Bags is a renowned producer of high-quality FIBCs in South Africa. We are able to manufacture up to 3.5-million bulk bags per annum and we can guarantee the quality of our products as a result of our ISO 9001 certification and in-depth quality inspection processes. All of our FIBCs have a minimum safety factor rating of 5:1. Here are some reasons why you need to consider switching from cardboard to bulk bags.

Bulk bags beat cardboard in almost every aspect

In many cases, bulk bags are a better packaging solution than cardboard as they are flexible, lightweight, durable, incredibly strong and recyclable. No matter which qualities you consider between bulk bags and cardboard, FIBCs will win almost every time. Bulk bags are also a more cost-effective solution as they can be reused multiple times before needing to be recycled.

When it comes to capacity and weight, FIBCs are more versatile than cardboard boxes. Custom Bulk Bags manufactures products that can hold between 500kg and two tonnes! The incredible strength of these FIBCs makes them more suitable for lifting and moving huge quantities of material than cardboard.

When dealing with large orders, bulk bags are cheaper than corrugated cardboard. They can also be folded and compressed for shipping and storage when not in use. Finally, since plastic is water-resistant, FIBCs are better than cardboard when it comes to damp materials or humid environments, where moisture and water would disintegrate the cardboard boxes.

Like cardboard containers, bulk bags are square in shape, so they can be filled to an accurate capacity. This shape also makes them easy to stack and store without toppling over. However, when discharging a bulk bag, a conical bottom can be fitted that allows flowable materials to exit the bag more easily than a flat bottom.

Compatibility with equipment

Bulk bags are a versatile packaging solution that are compatible with factory equipment, such as forklifts. They are easier to handle and move around a warehouse since they can be lifted by their loops or be placed on a pallet and lifted from underneath. This second lifting method is only available for cardboard boxes.

FIBCs are highly customisable, so they can be fitted with extra attachments and panels that allow them to fit with machinery. For example, spout attachments on the bottom of the bags make them easier to discharge into trailers or storage bins. Drawstring tops allow bulk bags to fit tightly around hoppers, which makes the filling process easier and cleaner. These attachments are not available on cardboard containers.

Overall, FIBCs offer several advantages over corrugated cardboard containers. Their customisability, flexibility, strength and durability make them the ideal packaging solution for a wide range of industries. For more information about our bulk bags, please contact us today.
