How Flour Mills Can Choose the Right Polyester Bag Sewing Thread
In the flour milling industry, packaging plays a vital role not only in protecting the product but also in maintaining compliance with food safety standards. Among the various packaging materials, bag sewing thread is often overlooked, yet it directly affects the durability, hygiene, and presentation of flour packaging. Choosing the right thread is therefore essential.
One of the most reliable options for flour mills is 100% spun polyester bag sewing thread, which combines food-grade safety with consistent performance. Below are the key factors flour mills should consider when selecting sewing thread for flour packaging.
- Since flour is a food product, packaging materials must meet strict safety regulations. The sewing thread used to close flour bags must not pose any risk of contamination.Our spun polyester sewing thread fully complies with both U.S. FDA and European Union food-contact requirements.
This ensures peace of mind for flour mills, as the thread can be used safely in direct contact with flour bags without compromising food safety.
- The thickness and evenness of the sewing thread directly impact bag closure quality.A thread that is too coarse may damage packaging material or result in uneven stitching.
A thread that is too fine may not provide sufficient holding strength.
High-quality spun polyester thread offers excellent uniformity, ensuring smooth operation on industrial bag-closing machines and consistent stitching across large production runs.
Our company offers different types of threads as options, such as Ne10s/3, Ne10s/4, Ne12s/4, Ne12s/5 ,Ne20s/6 ..etc.
- Flour bags are often heavy and require strong seams to withstand handling during transportation and storage.Our spun polyester sewing thread delivers high tensile strength and excellent abrasion resistance, reducing the risk of seam breakage.
Polyester fibers also resist moisture and chemicals better than cotton, making them more reliable under various storage conditions.
Although functionality comes first, appearance also matters. Flour mills often prefer neutral or standardized thread colors for a clean and professional look.
Our spun polyester threads are available in bright white and natural shades, with excellent colorfastness to maintain consistency across different batches.
Uniform color helps reinforce the brand image and ensures packaging has a neat and hygienic appearance.
Finally, efficiency is a priority in flour mill operations. Choosing a high-quality sewing thread reduces downtime and maintenance.
Consistent spool length, low breakage rates, and smooth runnability improve machine efficiency.
This translates to lower overall packaging costs and fewer interruptions on the production line.
Conclusion
For flour mills, the right sewing thread is more than a small detail—it is a crucial element of safe, durable, and efficient packaging. 100% spun polyester bag sewing thread offers the ideal balance of food safety compliance, strength, smooth operation, and cost-effectiveness. By choosing a thread that meets international standards and ensures reliable performance, flour mills can protect both their product and their brand reputation.
