The Importance of Testing Fabric Weight in Bulk Bags

Introduction 

At FlexSack, we bring over 30 years of combined expertise in the design, manufacturing, and testing of Flexible Intermediate Bulk Containers (FIBCs). As industry leaders committed to the highest standards of quality and safety, we know that ensuring your bulk bags meet the specified fabric weight is critical.

Fabric weight is the largest cost component of an FIBC, and discrepancies in weight can lead to significant issues, including bag failures, costly spills, and even personnel injuries.

In this post, we leverage our extensive experience to guide you through the importance of fabric weight testing and how you can ensure your bulk bags meet the necessary specifications.

Why Testing Fabric Weight Matters

FlexSack’s commitment to quality ensures that all our FIBCs meet the highest standards. However, discrepancies in fabric weight can still occur, particularly when working with less reputable suppliers. Fabric weight directly impacts the strength and durability of your bulk bags. Unfortunately, some suppliers may reduce fabric weight, shorten components, or eliminate them altogether without informing the end-user.

Such practices can lead to serious consequences, including catastrophic bag failures. By conducting routine testing, you can ensure that your FIBCs maintain their integrity, as FlexSack has been ensuring for decades.

How to Check Fabric Weight

Testing the fabric weight of a finished bulk bag is a straightforward process that can be done with the right tools. At FlexSack, our bulk bag experts utilize state-of-the-art equipment to ensure precise and accurate measurements:

What You’ll Need:

• A Fabric Sampler Cutter
• A High Precision Digital Gram Scale

Steps:

1. Collect Fabric Samples: Use the fabric cutter to cut swatches from the body panels, top panel, and bottom panel of the FIBC. Ensure samples are segregated and labeled according to their location on the bag.
2. Weigh the Samples: Place each swatch on the digital gram scale, multiply the reading by 100 to convert the measurement to grams per square meter (gsm), and record the results. You can convert gsm to ounces using a textile and fabric weight converter.
3. Compare with Specifications: After weighing, compare your measurements to the written specifications provided by your supplier. Note that non-load bearing components may be made of lighter fabrics, which is standard practice.

For tubular bags, avoid cutting swatches directly under the lift loops, as this area includes reinforcement fabric that can skew the weight measurements.
