Over the years, various industries such as packaging & labeling, stationery, etc. have seen increased applications of thermoplastic polymer such as polypropylene (PP). One such novel bulk packaging solution are the bulk bags also known as FIBC bags, specially designed for storage and transportation purpose and offer a light in weight, cost-effective primary as well as secondary packaging solution.

Bulk bags can in classified based on the type of resins used as type (A, B, C, D) wherein Type B bulk bags / FIBC’s are made of coated polypropylene threads consisting of low breakdown voltage to avoid the occurrence of highly energetic promulgating brush discharges which in turn are likely to ignite a dust-air mixture. Type B bulk bags enjoy high recyclability and are eligible to carry up to approximately 500 times its own weight.
Type B bulk bags are safely used in carriage of dry granules and powders materials that are combustible in nature. Moreover, Type B bulk bags take up negligible space when flat folded and requires no pallets as these bags have vital lifting loops. Add-on to this, many printing solutions readily available in turn make the Type B bulk bag a perfect promotion & advertising tool for numerous company/brand and also incline to display essential product handling information.
However, Type B bulk bags does not hold the ability to efficiently dissipate static electricity and hence, these bags at times may be applied in the existence of combustible dusts with MIE of higher than 3mj, but again with zero presence of flammable vapors / gases.
Type B bulk bags offers lowest packaging weight per tons of material to be stored or shipped and hence forms a perfect packaging solution. Also, this Type B bulk bags can be customized based on the material to be stored and further can be custom designed as per the client requirement.
Future Scope
The demand for bulk bag / FIBC bags is directly dependent on the material to be stored as well as environments to which this material is to be carried. It has been seen that, material used in manufacturing of Type B bulk bags has low breakdown voltage (less than 4KV) to evade “Propagating Brush Discharges” (PBD) which are extremely active and dangerous. Subsequently, the demand for Type C bulk bags which are electrically conductive or groundable has witnessed a sharp growth, especially in the in the emerging markets.
