Many industrial processes involve materials that are prone to build up a static charge if handled improperly. Static electricity is a danger, especially when flammable products are discharged from the bulk bag. However, there is an easy solution to protect your sensitive materials from these hazards: the Type C anti-static bulk bag.

These packaging solutions are made from fabrics that contain inter-connected conductive threads woven into the fabric. They are designed to prevent incendiary sparks and brush discharges when filling and discharging the bags, as they are connected to a grounding cable during use. Type C anti-static bulk bags are suitable for transporting flammable powders and solvents that may emit combustible gases or vapours.

Custom Bulk Bags is a leading manufacturer and supplier of high-quality bulk bags in South Africa. We produce up to 3.5 million bulk bags per year for various customers. All of our bulk bags have a minimum safety factor rating of 5:1 and are manufactured in accordance with international regulations and standards.

What is an antistatic bulk bag?

What is an anti-static bulk bag?

There are three types of anti-static bulk bags; all of which have the common purpose of preventing dissipative charges when storing and working with flammable materials. Some materials can create a static field when they are loaded and discharged. This static electricity can create small sparks that may ignite combustible materials, such as sawdust and chemical powders.

Type C anti-static bulk bags are designed to be used in applications where static electricity and combustion are potential concerns. The special fabric used to create these bags helps to neutralise any electric charges and prevent them from building up around the packaging material. These bulk bags are commonly used in food and pharmaceutical industries, as well as other applications for sensitive materials, such as fertiliser and chemicals.

Why use a Type C anti-static bulk bag?

A Type C anti-static bulk bag is highly resistant to electrostatic charge due to the use of an insulation material that is woven into the fabric. This material connects to a grounding wire, making it impossible for static charge build-up to in the bag when it is correctly grounded. 

This insulation material is also designed so that no electrical charges can be transferred through it when touched by humans or other objects. The result is no risk of static discharge or combustion. Fires and explosions can occur when the particles of highly flammable materials are rubbing against one another. 

Any resulting spark will ignite the material or the dust that emits from the moving particles. Type C bulk bags ensure that materials can be handled safely during loading and unloading operations, which helps ensure the safety of employees and facilities. 

Type C anti-static bulk bags are designed for use with granular products or powders, especially chemicals and reactive substances. If you’re unsure of whether these bags are needed for your operations, then speak to one of our consultants. They will give you expert guidance and information that will allow you to order the perfect bulk packaging products for your needs.
