FIBC Comparisons

A Type A FIBC is a standard bulk bag made from woven polypropylene without static electricity. These bulk bags should not normally be used where a flammable atmosphere with Minimum Ignition Energy (MIE) ≤ 1,000mJ is present. They are not treated and do not provide electrostatic protection for your application. The Type A Bulk Bag does not have any mechanism for dissipating static electricity and will not prevent the occurrence of highly energetic, and dangerous propagating brush discharges (PBD). These bags should not be used to carry flammable solvents or gases. At Elway Industries, we pride ourselves with the shortest lead time in the industry for Type A bulk bags. When to Use a Type A Bulk Bag: To transport non-combustible solids, nonflammable materials, non-flammable gases, and non-flammable solvents Do not use when: A flammable atmosphere is present with a Minimum Ignition Energy (MIE) ≤ 1,000mJ

Type A Bulk Bag Specifications Type A bulk bags can be custom made to customer specifications. *Custom dimensions available at no additional charge Type A FIBC Configurations The most common materials used include standard polypropylene fabric and non-conductive material. These bags can be either coated or uncoated. Since there are no requirements for static control in this type of bulk bag, there are no electrostatic tests specified in standards and no requirements for labeling. Common Applications Common products that use Type A bulk bags include: Non-combustible solids Non-flammable materials, gases, or solvents

FIBC Type B are made from insulating fabric, and usually has a voltage range of less than 6 KV. Elway manufactures these bags using plain polypropylene or other non-conductive material, and like Type A bulk bags these bags do not have any mechanism for dissipating static electricity. The difference is that Type B bulk bags are made from materials that have a low breakdown voltage to prevent the occurrence of highly energetic, and dangerous propagating brush discharges (PBD). It is important to note that these bulk bags can cause electrostatic shocks to operators, although shocks are not dangerous, they can be distracting and may lead to accidents. When to Use a Type B Bulk Bag: To transport dry, flammable products Do not use when: A flammable gas or solvent is present in the atmosphere around the bag

FIBC Type B Specifications Elway can provide custom Type B Bulk Bags that can meet various specifications. *Custom dimensions available at no additional charge Type B Bulk Bag Requirements We perform several tests for this bag including electrical breakdown voltage and propagating brush discharge testing. FIBC Type B Applications Safe use for this type include: Transporting dry, flammable products Environments with dust Environments with ingnition energies less than 3mJ

FIBC Type C are made from fabrics that have inter-connected static dissipative or conductive threads, which is why they're known as conductive FIBC or groundable FIBC. Originally they were made from entirely conductive materials, but now groundable Type C FIBC are more commonly made from non-conductive polypropylene interwoven with conducting yarns, normally in a grid pattern. The conductive yarns must be electrically interconnected and connected to designated ground or earth bonding points. The ground or earth bonding points must in turn be connected to a system ground or earth during all bulk bag filling and emptying operations. When to Use a Type C Bulk Bag: To transport combustible solids with MIE less than 3mJ and flammable vapors and gases with MIE > 0.14mJ Do not use when: Ground connection is not present or damaged

Type C Bulk Bag Specifications We are able to provide the shortest lead time in the industry for Type C bulk bags that meet a number of specifications. *Custom dimensions available at no additional charge FIBC Type C Requirements Elway preforms tests to meet Type C bulk bag requirements including electrical breakdown voltage and propagating brush discharge testing. Type C bulk bags also require testing for resistance to ground-able point. FIBC Type C Applications Common products that use Type C bulk bags: Combustible solids with MIE less than 3mJ Transporting flammable vapors and gases with MIE > 0.14mJ.

Type D or CROHMIQ ® Static Protective bulk bags are constructed from fabrics with static dissipative properties or threads to control fire-starting of discharges regardless of whether it's electrically grounded or ungrounded. Anti-static FIBC Type D bulk bags do not require grounding or earthing because they are made from conductive fabric designed to safely prevent the occurrence of incendiary sparks, brush discharges and propagating brush discharges. When to Use a Type D Bulk Bag: To transport flammable powders and combustible solids with MIE less than 3mJ Do not use when: A surface is contaminated or coated with conductive material such as water or grease

Type D Bag Specifications Type D bulk bags can be constructed to customer specifications. *Custom dimensions available at no additional charge FIBC Type D Requirements To ensure the quality of our products, tests are performed to meet Type D bulk bag requirements including electrical breakdown voltage and propagating brush discharge testing. Type D bulk bags also require discharge incendivity testing. Type D Bulk Bag Applications Common uses for this bulk bag include: Transporting flammable powders safely When loading and unloading in the presence of flammable vapors and gases with MIE greater than 0.14mJ Combustible solids with MIE less than 3mJ Do not use when the surface is contaminated or coated with cunductive material such as water or grease Static Protective Fabric Crohmiq Blue ® Bulk materials can create static energy during the filling and discharge process, this can cause an electrostatic discharge in the bulk bag and around the surface. Crohmiq Blue ® is a woven polypropylene static protective fabric for Type D FIBC bulk bags and it’s engineered to work safely in the presence of flammable materials, dust, or gases in the atmosphere. The CROHMIQ® static protective FIBC fabric safely dissipates charge into the atmosphere by a process called corona, providing safety not only to the customer but also his employees from an electrostatic discharge. Additionally, the properties of this fabric are permanent, so it’s static dissipative performance won’t decay with time nor will wash off during wet reconditioning process. As a result, over 6 million CROHMIQ® FIBC bags have been safely reused after wet or dry-process refurbishment! Today, over 50 billion pounds of products have been packaged in CROHMIQ® FIBC. Some common uses for this product are: Storage for chemicals Storage for minerals Storage for pharmaceuticals Storage for combustible-related products
