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.
Custom Bulk Bags is a leading manufacturer and supplier of world-class bulk bags in South Africa. 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.
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.
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.
Spot Color: A process (usually silk screening) where individual, spot colors are printed on any panel. In general, the practical limit is about 6 colours per panel. A “free” color may be gained within any trapped area using the bag fabric colour.
Important: Cannot do shades or gradients in silk screening.
CMYK: This process allows a full-colour, photographic-quality image to be printed. This is what is used on OPP Film bags but can also be used on a standard Polyfabric™ bag using Full-Color Transfer. This may be combined with silk-screening in order to print a complicated image (like a logo) within a larger, spot-color design.”
Full-Colour Roller Print: This is used for OPP film bags (either with woven or non-woven Polyfabric™). Any continuous tone (CMYK) image may be printed using this technique.
Please Note: Even if the gussets and/or bottom have no logos, the background colour must still be specified.
Paper Heat Transfer: Used exclusively with PET bags. Can be used to print either spot colours or do full-colour CMYK printing. This technique is not as precise as Full-Colour Roller Printing, but it does preserve the soft, fabricy feel of the material.
