UV PROTECTION

Although we do not recommend storing bulk bags outdoors, our fabrics provide UV protection for your products.

RECYCLABLE

Our fabrics are made from 100% virgin polypropylene making it suitable for recycling after use.

Bulk bags are fast & easy to transport

Flexible Intermediate Bulk Containers have a variety of lifting options. This makes it easy to customize the bag to fit the lifting and transportation equipment that you already have at your facility. With lifting options such as cross corner loops, edge corner loops, additional lift loops, single and double loading belts, it makes it easy to find a lifting option that works for your forklift, crane, and/or hoist at your facility.

They also have the ability to store and transport all types of products/materials, including combustible and flammable materials, making them a perfect fit for most businesses that store and transport large amounts of dry flow-able products.

TYPES OF FIBC FABRICS

FIBCs are most often made of woven polypropylene, (can be coated with polyethylene and Polypropylene films etc). Bag dimensions are most commonly made with a base of 35″ to 40″ (length x width) and the bag height can be from 20″ to 80″ tall. Average SWL (safe working load) is normally 2,205 pounds or 1000 kilograms. The upper limit SWL is about 4,400 pounds. The empty bag that will hold 2,205 pounds will only weigh about 7 pounds!  FIBC Bags are classified according to one of four Types: A, B, C and D. All these Types are defined by the construction of the Bulk Bags, the intended use and performance requirement criteria.

TYPE "A" FABRIC BULK BAGS 

Type A bulk bags are made from standard polypropylene material which is a non-treated insulating fabric. They have no special electrostatic safety features. Static electricity is generated as products move over the inside surface of the bulk bag when they are being filled or discharged. As there is no static protection provided by Type A bulk bags, these are not to be used for combustible materials or utilized in flammable or combustible environments. No requirements are specified for Type A FIBCs as they are not intended for use in potentially explosive atmospheres.
  • No static protection
  • Used safely to transport non-flammable products
  • There are to be no flammable solvents or gases present around the bag
  • DO NOT USE to transport flammable products

TYPE "B" FABRIC BULK BAGS

Type B bulk bags are very similar to the Type A bags as they are made from the standard polypropylene material, they too do not have the ability to dissipate static electricity efficiently. The difference is that the material used is an insulating fabric but this has a low breakdown voltage (less than 4KV) to prevent propagating brush discharges (PBD) which are highly energetic and dangerous. Type B bags can prevent PBD, however normal brush charges can still occur so these bags cannot be considered to be antistatic in any way. Type B bags may be used in the presence of the combustible dusts with MIE of greater than 3mj but in the absence of flammable vapors of gases.
  • Used to safely transport dry, flammable powders
  • There are to be no flammable solvents or gases present around the bag
  • DO NOT USE to transport flammable products

TYPE "C" FABRIC BULK BAGS

These are bulk bags known within the industry as conductive or groundable bulk bags or conductive FIBCs. Constructed from non conductive polypropylene material interwoven with conductive yarns that form a grid pattern, these are designed to control electrostatic charges by grounding. The bag MUST be electrically grounded during filling and emptying - this is essential to the safe use and performance of a Type C bag.
  • Used safely to transport flammable powders
  • Used safely when flammable solvents or gases are present around the bag
  • DO NOT USE when ground connection is not present or has become damaged

TYPE "D" FABRIC BULK BAGS

Type D bulk bags are also called antistatic bulk bags. A type D bag is constructed from antistatic fabric which has antistatic or static dissipative properties to safely prevent the occurrence of incendiary sparks, brush discharges and propagating brush discharges and does not require grounding.
  • Used safely to transport flammable powders
  • Used safely when flammable solvents or gases are present around the bag
  • DO NOT USE when the surface is contaminated or coated with conductive material such as water or grease

FOOD GRADE BULK BAGS

Food grade bulk bags are made with the intent of putting food products into the bags. A bulk bag that is manufactured in a facility that has undergone an audit and is certified by a food safety standard.

UN BULK BAGS

UN Certified bulk bags are designed to handle products that the United Nations considers hazardous material. The international transport of dangerous goods in Bulk Bags is regulated by a number of international codes based on the United Nations Recommendations on the Transport of Dangerous Goods (also known as the Orange Book). This divides bulk containers into 6 categories namely: metal, flexible, rigid plastics, composite, fibreboard and wooden. There are four types of FIBCs made from woven polypropylene for dangerous goods:
  • 13 H 1 - Woven plastics without coating and without liner
  • 13 H 2 - Woven plastics, coated and without liner
  • 13 H 3 - Woven plastics, uncoated and with liner
  • 13 H 4 - Woven plastics, coated and with liner.

HACCP is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. 

HACCP (hazard analysis and critical control points) | Conitex Sonoco

Such packaging is often referred to as “type-approved”, “UN Approved” or “UN certified” “POP” (performance oriented) and is marked in a particular way, prefixed by the UN Packaging symbol and followed by alpha numeric codes. It is not only important to select the correct UN approved packaging, but it is also important to use it as it was tested and carefully follow the closure information provided by the manufacturer.
