Nowadays, FIBC bags (bulk bags, big bags) are more and more widely used in many countries around the world. After many years of providing PP products, we realize that customers sometimes do not understand clearly what is the difference between standard bulk bags and clean FIBC bags. Understanding the criteria for cleanliness within a bulk bag is important to help ensure there’s no contamination within a bag or the final products.

Normally in a standard production of FIBC bags, there are no cleanliness standards specified on the bag. Therefore, this type of FIBC bag will be used to store common goods such as wood pellets, minerals, fertilizers, etc. Then you will inevitably find thread and fabric scraps inside the bag. However, if you want to use jumbo bags to store foodstuff or food-related ingredients, it is imperative that the bag has to be produced on clean production. In this case, all FIBC bags will have to go through a cleaning machine to remove dust, hair, or thread crumbs. At the same time, the factory area must also ensure cleanliness according to strict standards.

When reviewing your bag requirements, please take a moment to consider what contaminations levels are acceptable for your application and finished product.

The information below should help determine what grade of cleanliness you require:

Standard Bag: No extra cleaning.

•Industrial Clean: Made in standard production & vacuumed out.

Industrial Clean with Metal Detection: An additional option that could find potential machine parts from a crash, needles, scissors, or other items used on the sewing floor.

Food Grade or Clean Room Production: Bags manufactured in special cleanroom facilities with specific procedures in place. Vacuuming and metal detection are standard in most cases.

Pharma Clean: Bags manufactured in a special clean room with filtered air and specific procedures in place. Vacuuming and metal detection standard in most cases.

It’s important to remember these cleanliness levels are subject to human error, so good facilities and processes are key to minimizing all risks. Start by addressing your tolerance and risk of contamination and specify these needs when purchasing bags. Make sure you’re partnering with a company that understands the various cleanliness requirements and has the abilities to help minimize contaminations risks. Our team is equipped with the knowledge and ability to offer alternate solutions when a higher grade of cleanliness is required.
