Purchasing managers have two options when sourcing bulk bags; they can either buy from a third-party supplier or source packaging products directly from the manufacturer. Both options have their advantages, but buying bulk bags from a manufacturer is a great way to keep costs low without compromising on quality.

Custom Bulk Bags is a leading manufacturer and supplier of bulk bags in South Africa, offering high-quality packaging solutions to our customers. We produce up to 3.5 million bulk bags per year; all of which have a minimum safety factor rating of 5:1 and are manufactured in accordance with international regulations and standards.

As a bulk bag manufacturer, we know the ins and outs of the industry. That’s why we’re able to deliver high-quality products at competitive prices. If you buy directly from a manufacturer, there are three main benefits.

Everything you need to design your own bulk bags

A manufacturer offers guaranteed quality

Quality control is a vital component of our business. Bulk Bag manufacturers take it very seriously as their entire business depends on the quality of their products. Through these control processes, the manufacturer guarantees that the products are delivered in a condition that meets the customer’s specifications and expectations.

A bulk bag manufacturer is also likely to carry out several tests on their products to ensure that they perform as designed and expected. These can include topple tests, scuff tests and load tests – the results of which will determine the safety factor rating and other criteria for each batch of bulk bags.

When you buy directly from the manufacturer, you can minimise the risk of defects. Shipping bulk bags from our factory to your business eliminates any chance of a defective bag being sent to you. This comes back to rigorous quality control checks, but it also prevents bags from sitting in storage in a third-party supplier’s warehouse for too long.

Custom Bulk Bags holds ISO 9001 certification for quality management systems. This, along with our UN-certified designs, guarantees that our products will meet your packaging needs. These assurances of quality and standards are important as they not only improve safety when handling loaded bulk bags but also help our customers reach their targets for waste control and budgets.

Faster lead times

When sourcing bulk bags directly from the manufacturer, you can expect faster lead times. Since there’s no middleman – no third-party supplier – between you and your bulk bags, delivery times are greatly reduced. As the bags are manufactured in-house, you also don’t have to wait for additional stock to arrive before delivery takes place.

Custom Bulk Bags maintains a well-stocked inventory throughout the year. This allows us to deliver our products to local customers with speed and efficiency, which helps to reduce operational costs for our customers.

A reliable bulk bag manufacturer will deliver stock at regular intervals to ensure that your business always has enough bulk bags available. This not only reduces the need for storage space, which saves warehousing costs, but it also allows your employees to focus on their core tasks without having to worry about inventory.

Reduced costs of transportation and storage

When sourcing from a manufacturer, you’ll be able to buy only what you need. It also helps to lower shipping costs, especially if your bulk bag manufacturer is located close to your premises. This eliminates the need for multiple shipments and helps save you money on transportation costs.

If you’re buying in bulk, you also don’t have to keep as much stock on hand since you’ll be able to purchase only what’s needed at any given time. You won’t have any excess stock sitting in storage, taking up space and costing money all year round. However, if you do end up with leftover bulk bags from previous projects, storing them is not difficult as they can be folded up to minimise space. 

Purchasing managers and business owners need to understand why it’s beneficial to buy bulk bags directly from the manufacturer. By doing so, you can ensure that your products are made with high-quality materials and crafted by experienced professionals who know how to make them right. 

Additionally, purchasing directly from Custom Bulk Bags means that we can offer quick lead times on orders as well as lower prices per ton of inventory because there are no third-party businesses involved in the supply chain. For more information about our bulk bags, please contact us today.
