The importance of quality in FIBCs

Quality is one of the most important factors to consider when choosing a FIBC manufacturer or supplier. Substandard bulk bags can not only lead to product contamination and increased wear and tear, but they can also put your employees in harm’s way when lifting and handling fully loaded bags.

Custom Bulk Bags conducts various tests on our products to ensure that they meet strict standards and quality controls. These include topple, strength and wear tests. As a result, our bulk bags are UN-certified and are guaranteed to meet your expectations for bulk packaging solutions.

Why a South African supplier can benefit your business

Choosing a local supplier like Custom Bulk Bags will offer several benefits to your company. The first benefit is improved delivery times as we can optimise lead periods and expedite the delivery process. Products that are imported can face lengthy delays at shipping ports and customs, but working with a local manufacturer prevents this.

The next benefit is reduced shipping costs as FIBCs are extremely lightweight. They can be folded and flattened when empty, and the weight of the bags has a minimal impact on the overall weight of a consignment. This keeps costs low. In addition, multi-trip bulk bags are reusable, meaning that you can extract maximum value out of your initial investment.

As a local supplier, we understand the unique challenges faced by South African businesses. This allows us to offer personalised solutions and a better customer experience over foreign suppliers. We hold numerous international certifications for standards, so you can rest assured that our products are world-class.

When it comes to bulk bags, quality and reliability are paramount. Custom Bulk Bags is a trusted supplier of high-quality FIBCs. Our customers can rely on their local expertise to ensure safe and secure storage of valuable goods. Don’t settle for anything less than the best when it comes to your bulk bag needs.
