What are bulk packaging bags and which one is right for you?
Bulk packaging bags are large, heavy-duty bags designed for handling and transporting large quantities of granules, powders, liquids and other materials.
They are typically used for long- and short-term storage, including temporary storage between stages of production and transportation – ranging from between factories to cross continent shipping.
Whether you’re in oil & gas, chemicals, logistics or manufacturing, finding the right bulk packaging bag is essential to keeping operations running smoothly.
As a dedicated UK manufacturer of bulk packaging bags – and the first to bring the innovative ‘Original Big Bag’ to market – we offer a wide variety of heavy-duty bags to suit different environments, applications and industry requirements.
So, we thought we’d take a look at the types of Big Bags we supply to help you determine the right bulk packaging bag for your needs.
But first, what’s the Original Big Bag?
At Structure-flex, we’ve manufactured the innovative Original Big Bag since its design in 1970. It provides exceptionally safe storage for bulk powders and granules weighing up to 2,500kg.
Independently validated with an 8:1 safety factor and manufactured from waterproof and UV-resistant thermoplastic coated textiles, our Big Bag is ideal for uncovered external storage – something not possible with disposable polypropylene FIBC (Flexible Intermediate Bulk Container) bags.
Across our range of Big Bag products, we offer customisation options to suit any requirement, including choice of body shape, a conical or flat base, sight widows, base protection and over 50 colour options.
Our Original Big Bag is renowned for its durability and reliability, previously used by many of Europe’s leading manufacturers in chemicals, food and oil & gas and in hostile environments, including the Middle East and Gulf of Mexico.
Our diverse range of Big Bag products
Strap Bag
Our reusable strap bags offer a robust and long-lasting alternative to traditional one-trip FIBC polypropylene bags.
Designed for superior transport stability and shape retention when full, these bags are manufactured with high-frequency welding, PVC-coated textiles and welded straps to resist dust, moisture and UV damage.
This reliable design significantly extends the lifespan of each bag, making them a smart and sustainable choice across many varying industries.
Compatible with standard lifting equipment like forklift trucks, our strap bag can be used for a wide range of applications, from construction and manufacturing, to logistics and shipping.
Plus, this bag where required, can be designed and tested to achieve the UN Chapter 16 certification for the transport of dangerous goods, meaning it’s highly rated for handling hazardous goods in more specialised industries, including chemical, pharmaceutical and waste management.
Ring Bag
Our ring bag has a circular body design and central lifting ring to help distribute weight and stress evenly, making it a safer and more secure option for heavy-duty lifting.
Unlike traditional lifting strap systems, our specialist ring bag is used in conjunction with our bespoke OEM hinged lifting ring. This eliminates any stress-related damage to the straps and bag body, which ultimately helps to extend the bag’s in-field service life.
As with all of our bulk bags, we construct our ring bags using high-frequency welding and PVC coated fabrics to ensure a complete dust and waterproof seal and complete UV protection.
Our specialist ring bag is best for crane and hoist-based operations or in tough industrial environments, such as those found on oil rigs.
Baffle Bag
As the name suggests, our baffle bag features internal ‘baffles’, which are pieces of fabric that are HF welded inside at the bag’s corners, connecting the opposing walls to each other to retain its shape.
This limits the movement of its contents and provides greater stability.
The baffles incorporate cut-outs to promote even product flow during filling, use and emptying, meaning it’s the ideal choice for free-flowing and semi-liquid contents.
Plus, the stable design means our baffle bag is perfect for use during warehouse transit and storage, where stacked bags require stability so they don’t fall into neighbouring loads and incur damage or abrasion.
