How Food Processing Companies Can Choose the Right Polyester Bag Sewing Thread
In the food processing industry, packaging materials play a critical role in protecting products, ensuring safety, and strengthening brand reputation. One often-overlooked but essential component of secure packaging is the bag sewing thread. For flour, grains, sugar, rice, animal feed, and other food products packed in woven or paper sack bags, the choice of sewing thread directly affects sealing strength, food safety compliance, and packaging efficiency.
Among the many options available, 100% spun polyester bag sewing thread has become the preferred choice for food-grade packaging due to its durability, cleanliness, and compliance with international safety standards.
- Food packaging must adhere to strict regulations to avoid contamination. Sewing thread is no exception.
Spun polyester bag sewing thread meets both U.S. FDA and European Union food-contact safety requirements.
This ensures that the bags sealed with polyester thread are safe for direct use in food packaging environments.
At Henan Deman Packing Co., Ltd., our production facilities are certified under ISO9001 and ISO14001 management systems, guaranteeing consistent quality and sustainable production practices.
- Different food products and bag weights require threads of different specifications. The most common models include:
NE12/5, NE12/6,NE10/4 – strong and thick, suitable for heavy-duty packaging such as flour and rice.
NE12/3, NE10/3, NE12/4,NE20/6 – medium thickness, ideal for sugar, grain, and feed bags.
NE20/6 ,NE10/3– finer thread, suitable for lighter packaging or applications where smoother seams are required.
Choosing the right model depends on the weight of the bag, the type of product being packed, and the sewing machine used.
- Sewing thread is supplied in different cone sizes to match equipment needs:
200g -250g small cones – designed for portable sack sewing machines, widely used in manual or semi-automatic operations.1kg to 8kg large cones – used in automatic bag-closing sewing lines, ensuring continuous operation with fewer spool changes, thus improving efficiency.
By matching spool size with production methods, food processors can reduce downtime and increase productivity.
In addition to functionality, color can enhance both product traceability and brand identity.
Different thread colors help factories easily distinguish between product types or grades.
Customized thread colors can strengthen brand recognition on store shelves.
Henan Deman Packing Co., Ltd. offers a wide range of colors to meet both functional and branding requirements.
