Bulk bags can be ordered with many optional extras, which is why they are so customisable. One feature that is important to consider is the lifting loop design. These come in various sizes and styles, but their basic function is always the same – to serve as a handle or pick-up point for the bulk bag. 

Loops are made from high-tensile woven polypropylene and can be rated to lift up to two tonnes. Custom Bulk Bags (CBB) is a leading manufacturer and supplier of bulk bags in South Africa. Our products can be tailor made to suit your specific needs to speak to one of our expert consultants about the right lifting loop design for your business.

Our bulk bags come standard with a minimum 5:1 safety factor rating, which means that they can hold at least five times their intended load without breaking. CBB has a manufacturing capacity of 3.5-million bags per year, including weaving and extrusion.

Why you need to consider automation for bulk bag filling

Types of loop design

There are four main types of lifting loop design, as outlined below:

  1. Single loop – The single loop is the most cost-effective design and are constructed using tubular polypropylene fabric. This design does not require additional loops to be sewn onto the bag, rather they are created using sleeves that wrap around the fabric of the bulk bag. They are easy to handle but are not the strongest design.
  1. Cross corner loop – These loops are commonly found on tubular bulk bags. The loops are sewn onto the body of the bag to form an arch over each corner. They are shorter than other loop designs but are a cost-effective solution.
  1. Corner seam loop – These loops are commonly used on U-Panel and 4-Panel bulk bags. The loops are sewn along the side seams of the bags and they begin and end at the same point, forming a teardrop-shaped loop. These loops are extremely strong but more costly than cross corner loops.
  1. Stevedore straps – These are additional lifting straps that attach to cross corner or corner seam loops. The Stevedore strap connects adjacent loops or all four loops. They create a single lifting point and make it easier to pick up bulk bags with a forklift or crane. They also allow multiple bags to be picked up at once with a multi-hook crane system.

Which loop design is best?

The answer to this question obviously depends on your requirements and lifting methods. The Stevedore strap is a great all-around solution and is ideal for companies that use forklifts and cranes to pick up and move many bulk bags at a time. Each design will have its pros and cons, so it’s important to speak to a bulk bag supplier before placing an order.

The expert consultants at CBB will be on-hand to guide you through the design choices and optional extras available to you. They will ask for information about your company, equipment, processes and desired outcomes in order to derive the best loop design for your needs.
