Bulk bags can completely change how businesses handle and store goods. They are a popular packaging product in different industries due to their affordability, lightweight design, amazing adaptability, and inherent strength. Although a bulk bag’s overall construction affects how well it performs, some design components are essential for improving both the structural integrity and usefulness. The perimeter band is one such element.
Custom Bulk Bags is a leading manufacturer and supplier of bulk bags in South Africa. We produce up to 3.5 million units per year, and our products can safely hold between 500kg and two tonnes of material per bag. We offer various customisable bulk bags and aim to match your bags to your specific needs.
The perimeter band – a foundation of strength
The perimeter band, sometimes referred to as a support band or stiffener band, is a reinforcing strip of woven polypropylene fabric that is sewn around a bulk bag’s upper circumference. It creates a sturdy ring at the top of the bag. This seemingly straightforward component significantly increases the bag’s overall strength, especially its capacity to hold its shape while being filled, lifted, and – most importantly – stacked.
The perimeter band distributes stress and keeps the bag’s top from buckling or collapsing, particularly when it’s loaded with large quantities of goods. In the absence of a high-quality perimeter band, the bag’s top edges may bend inward, reducing stability and perhaps making stacking dangerous.
The weight of the bags above put a lot of downward pressure on the stack. By keeping the bag in its proper shape, a sturdy perimeter band ensures that the weight is distributed evenly and steadily across the bag’s foundation. By doing this, localised stress spots that can cause bag failure are prevented.
As a buyer, you must be able to determine the perimeter band’s quality to guarantee the durability of your bulk bags. A well-built perimeter band is indicated by several features:
- The material should be made of high-denier woven polypropylene, which is comparable to the bag’s main body fabric in terms of strength and durability.
- The band’s breadth matters; a broader band typically provides greater reinforcement and support.
- Strong, uniformly spaced stitching using high-strength thread should be used to secure the perimeter band to the bag body. For further security, look for stitching with many rows.
- A high-quality perimeter band will feel solid and withstand deformation under pressure. It shouldn’t buckle or fold readily.
Advantages of perimeter bands
A well-built perimeter band adds many advantages that enhance a bulk bag’s functionality and performance:
- Improved stability – The main advantage is that it gives the bulk bag more stability, particularly when it’s packed. This makes handling and manoeuvring safer and easier, especially when using forklifts. This stability is also essential for a more consistent and thorough product distribution during the filling process.
- Increased strength – The perimeter band reinforces the top of the bag, which is subjected to a lot of strain when being lifted and handled. By distributing the lifting forces more equally throughout the bag’s body, this additional layer of woven material reduces the pressure on the main body fabric and the lifting loops.
- Better handling – In general, a bulk bag with a sturdy perimeter band is simpler to handle. Forklift operators can easily insert their tines and safely lift the bag thanks to the well-defined and stable opening. During loading and unloading processes, this increased handling efficiency can save time and lower the chance of accidents.
- Consistent shape for stacking – The consistent shape that a perimeter band offers for stacking is arguably its most important advantage. It guarantees a more consistent and balanced stacking profile by keeping the bag’s top from collapsing or bulging. Since stacked bags are less prone to move or topple, storage space can be used more safely and effectively.
