At ITP Packaging, we offer a wide range of FIBC Bulk Bags designed to provide safe, efficient storage and transportation for dry, flowable materials. Whether you’re moving sand, grains, chemicals, or food products, our bulk bags are manufactured for performance, safety, and versatility.

FIBC stands for Flexible Intermediate Bulk Container, a type of industrial packaging designed for the storage, handling, and transportation of dry bulk materials. Commonly referred to as bulk bags, jumbo bags, ton bags, or builders bags, FIBCs provide a cost-effective and efficient method of moving large quantities of product.

Manufactured primarily from woven polypropylene fabric, FIBCs are lightweight yet incredibly strong. Depending on their design, they can safely carry loads ranging from 250kg to over 2,000kg while remaining easy to fill, transport, stack, and discharge.

FIBC bags are used across a wide range of industries including agriculture, construction, food production, chemicals, pharmaceuticals, minerals, recycling, and manufacturing.

Benefits of Using FIBC Bulk Bags

The popularity of FIBCs is largely due to their versatility and efficiency.

• High Capacity – Bulk bags can hold significantly larger volumes than traditional sacks, reducing packaging requirements and improving handling efficiency.

• Full opening base

Selecting the correct configuration can improve filling efficiency, reduce product waste, and simplify discharge operations.

Safe Working Load (SWL) and Safety Factor

Every FIBC bag is rated according to its Safe Working Load (SWL), which specifies the maximum weight the bag can safely carry. Bulk bags are also tested using a Safety Factor (SF).

Common classifications include:

• 5:1 Safety Factor – Single-trip FIBCs intended for one-time use.
• 6:1 Safety Factor – Multi-trip FIBCs designed for repeated use under controlled conditions.

Choosing the appropriate SWL and safety factor is essential for safe material handling operations.

UN Approved Bulk Bags for Hazardous Materials

Certain products classified as dangerous goods require specialised packaging. UN Approved FIBC bags are independently tested and approved for the transportation of specific hazardous materials in accordance with international regulations.

These bags undergo rigorous testing for:

• Top lift performance
• Stacking capability
• Tear resistance
• Drop testing
• Stability under load

Businesses transporting hazardous powders, chemicals, or industrial materials should ensure the correct UN certified packaging is selected for the relevant product classification.

Food Grade FIBC Bags

Food manufacturers frequently use food grade bulk bags for ingredients such as:

• Flour
• Sugar
• Starches
• Grains / Seeds
• Animal feed
• Food additives

Food grade FIBCs are produced using controlled manufacturing processes and materials designed to minimise contamination risks.

Depending on the application, additional features such as liners, dust proof seams, or clean room manufacturing may be specified.

Bulk Bag Liners

Many FIBCs can be supplied with internal liners to provide additional product protection.

Liners may help:

• Protect against moisture
• Improve product containment
• Prevent contamination
• Reduce product loss
• Provide chemical resistance

Liners are commonly used for fine powders, food ingredients, and specialist chemicals.

Why Businesses Choose FIBC Bulk Bags

Flexible Intermediate Bulk Containers have become one of the most widely used forms of industrial packaging because they offer an exceptional balance of strength, flexibility, efficiency, and cost effectiveness.

From construction aggregates and agricultural products to food ingredients and specialist chemicals, bulk bags provide a reliable solution for storing and transporting large quantities of material while reducing handling costs and improving operational efficiency.

Whether you require standard bulk bags, food grade FIBCs, UN certified packaging, ventilated bags, conductive bags, or custom manufactured solutions, selecting the right FIBC can significantly improve supply chain performance.

Understanding Type A, B, C and D FIBC Bulk Bags

When handling powders, chemicals, or other materials that may generate static electricity, selecting the correct type of FIBC is critical. Static electricity can accumulate during filling, transport, and discharge operations, potentially creating a fire or explosion hazard in environments containing combustible dusts, vapours, or gases.

To address these risks, bulk bags are categorised into four primary electrostatic classifications: Type A, Type B, Type C and Type D.

Type A FIBC Bags

Type A bulk bags are manufactured from standard woven polypropylene and provide no special protection against static electricity. While Type A FIBCs are suitable for transporting many non-flammable products, they should not be used where flammable gases, vapours, solvents, or combustible dust clouds are present.

Typical applications include:

• Sand
• Gravel
• Fertilisers
• Building materials
• Non-hazardous powders

Type A bags are generally the most economical option and are widely used throughout the construction and agricultural sectors.

Type B FIBC Bags

Type B bulk bags are similar in construction to Type A bags but are manufactured using materials that limit the formation of highly energetic brush discharges. While Type B bags reduce certain static risks, they do not dissipate static electricity and should not be relied upon where flammable vapours or gases are present. Type B FIBCs are commonly used for handling dry, combustible powders where the primary concern is the prevention of propagating brush discharges.

Typical applications include:

• Fine chemical powders
• Certain mineral powders
• Industrial dry ingredients

Type C FIBC Bags (Conductive Bulk Bags)

Type C bulk bags, sometimes referred to as conductive FIBCs, incorporate conductive threads woven throughout the fabric. These conductive elements must be connected to a verified earth or ground point during both filling and discharge operations. When correctly grounded, static electricity is safely dissipated, significantly reducing the risk of electrostatic ignition.

Typical applications include:

• Flammable powders
• Solvents
• Chemical products
• Potentially explosive dusts

It is essential that Type C bags are correctly grounded before use. Failure to do so can negate their protective properties.

Type D FIBC Bags (Static Dissipative Bulk Bags)

Type D FIBCs provide static protection without the need for grounding. Manufactured using specially engineered static-dissipative fabrics, Type D bags safely dissipate electrostatic charges into the atmosphere, preventing dangerous charge accumulation during filling and discharge operations. As they do not require an earth connection, Type D bags offer operational advantages in environments where grounding procedures may be difficult to implement or verify.

Type D FIBCs are often specified within:

• Chemical manufacturing
• Pharmaceutical production
• Food processing
• Hazardous powder handling
• ATEX-regulated environments

Which FIBC Type Is Right for Your Application?

Selecting the correct FIBC classification depends on several factors, including the product being handled, the presence of combustible dust, and whether flammable gases or vapours may be present during operation.

Businesses should always undertake a suitable risk assessment and consult relevant health and safety guidance when specifying FIBC packaging.
