Why change from cardboard packaging to bulk bags

Businesses typically have two options when it comes to packaging bulk quantities of material: corrugated cardboard or polypropylene bulk bags (also called flexible intermediate bulk containers, or FIBCs). Due to supply chain disruptions, cardboard prices have recently gone up worldwide. However, the cost of bulk bags has not changed—especially when purchased from a local supplier or manufacturer.

In South Africa, Custom Bulk Bags is a well-known manufacturer of FIBCs of the finest quality. Due to their ISO 9001 certification and thorough quality inspection procedures, they are able to produce up to 3.5 million bulk bags annually and can guarantee the quality of their products. Every one of their FIBCs has a safety factor rating of at least 5:1. Here are a few reasons for switching from cardboard to bulk bags.

Bags in bulk outperform cardboard in practically every way

Due to their flexibility, lightweight, incredible strength, durability and recyclable nature, bulk bags are generally a superior packing alternative to cardboard. No matter which factors you compare between cardboard and bulk bags, FIBCs will almost always come out on top. Bulk bags are also a more affordable option because they can be recycled after several reuses.

FIBCs can handle a broader range of weights and capacities than cardboard boxes. Bulk Bags can often hold between 500kg and two tonnes! These FIBCs are incredibly strong and are far superior to cardboard in terms of lifting and carrying large amounts of material.

Bulk bags are also more affordable than corrugated cardboard when dealing with large orders. Additionally, they can be compressed and folded for shipping and storage when not in use. FIBCs are superior to cardboard when it comes to damp materials or humid conditions because plastic is water-resistant, whereas moisture and water will cause the cardboard boxes to disintegrate.

Like cardboard containers, bulk bags are square in shape, so they can be filled to an accurate capacity. They are also easy to stack and store without toppling over because of their design. Conical bottoms, as opposed to flat bottoms, allow flowable materials to exit a bulk bag more easily as it is being discharged.

Equipment compatibility

Bulk bags are a versatile packaging solution that is compatible with forklifts and other industrial machinery. Given that they can be hoisted by their loops or placed on a pallet and lifted from underneath, they are easier to handle and move around a warehouse.

Since FIBCs are highly customisable, it is possible to add panels and additional attachments to make them compatible with machinery. The bags can also be discharged into trailers or storage bins more easily due to spout attachments on the bottom. Bulk bags with drawstring tops fit snugly around hoppers, facilitating and improving the filling process. There are no such attachments for cardboard containers.

Overall, FIBCs are superior to corrugated cardboard containers in a number of ways. For a variety of industries, their flexibility, strength, and durability make them the ideal packaging solution.
