Understanding Food-Grade Bulk Bags

As a supplier of packaging products across a wide variety of industries, our FlexSack experts are frequently asked about food grade bulk bags. When discussing food-grade bags, it’s important to determine exactly what level of “food graded-ness” fits the end user’s application.

Industrial Grade Bulk Bags

Most bulk bags are produced to an industry-standard known as “Industrial Grade.” These bags are produced under the standard production process with no additional measures being taken to prevent the chance of loose material or contaminants from the production processes, such as thread or PP flakes being present in the finished bag.

Clean Room Manufactured Bulk Bags

The next step up from an Industrial Grade FIBC is “Clean Room Manufactured.” These bags are manufactured in a controlled environment and undergo additional processes to reduce the likelihood of contaminants being present in the finished bag. These additional processes include air washing, vacuum cleanout, light table inspection, metal detection, and ultrasonic cutting. Generally, these additional cleaning steps are specified per the application.

Certified Food-Grade Bulk Bags

The highest level of “food-grade” bags, FIBCs, are produced in third-party audited and certified production facilities, meeting global standards such as American Institute of Baking (AIB), British Retail Consortium (BRC), and ISO22000. Under these certifications, rigorous environmental standards and manufacturing processes are followed to ensure that these bags uphold the highest standards for food cleanliness in the packaging of food products.

Compliance and Standards

As is with every bag FlexSack supplies, both Industrial Grade and Clean Room Manufactured FIBCs meet the requirements set forth under USA FDA 21 CFR Part 110.3, FDA CFR Title 21,177.1520, and IS 10910 for packaging materials intended to come into contact with human food. Therefore, in a generalized sense, these bags can be considered food-grade. For more information, see our food safety statement.

Food-Grade Bulk Bag Comparison Chart

Reference the below chart for measures taken at each level of food safety to ensure the right product is delivered for the specified application.

What Are Food-Grade Bulk Bags?

Food-grade bulk bags are designed for use in food-grade facilities and for packaging food products. They must be manufactured in clean environments adhering to stringent hygiene standards, such as those certified by the American Institute of Baking (AIB), Safe Quality Food Institute (SQF), or the British Retail Consortium (BRC).

What Certifications are Important for Food-Grade FIBCs?

Key certifications for food-grade FIBCs include:

• FDA compliance for food contact materials, specifically 100% virgin polypropylene resin.
• GFSI-recognized certifications like BRC, SQF, and FSSC 22000.
• AIB certification, which ensures the manufacturing facility meets high standards of cleanliness and hygiene.

Can Any Bulk Bag Be Used with Food-grade Products If It Has a Food-grade Liner?

No, not all bulk bags are suitable for food-grade products even if they have a food-grade liner. The entire bag must be manufactured from 100% virgin polypropylene resin to ensure no contamination from recycled materials.

What Is HACCP And Why Is It Important for Food-grade FIBCs?

HACCP (Hazard Analysis and Critical Control Points) is a systematic preventive approach to food safety that identifies potential hazards and implements control measures to reduce or eliminate risks. It is crucial for ensuring the safety and hygiene of food-grade FIBCs.

How Do You Handle Static Electricity in FIBCs?

Static electricity can accumulate during the filling and emptying of FIBCs, posing a risk of ignition in flammable atmospheres. To mitigate this, Type C FIBCs must be grounded to prevent static discharge.

Can Food-grade Bulk Bags Be Reused?

Reusing bulk bags is possible if they are designed for multiple uses, typically indicated by a 5:1 Safety Factor. However, reusing bags can be risky due to potential wear and damage that may compromise their integrity.
