Six-Ply 20S/6 Spun Polyester Bag Closing Thread Matched to Portable Bag Closer Machines

MH 20S/6 Spun Polyester Bag Closing Thread is a six-ply sewing thread made from 100% spun polyester and built to close filled sacks on portable bag closer machines.

MH 20S/6 Spun Polyester Bag Closing Thread stitches woven PP sacks, kraft paper sacks and multi-wall paper bags across grain, flour, animal feed, fertiliser and chemical packing lines. MH supplies the thread in natural white and raw white, and dyes it to a buyer's own colour reference when seam colour is used to separate product grades on the line.

Key Selling Points

• Portable closer compatibility: MH spun polyester bag closing thread is engineered around the tension range and looper geometry of portable bag closer machines, so on-site operators get consistent stitch formation without retiming the head.
• Spun fibre grip: The spun polyester surface of this bag closing thread behaves like cotton under the presser foot, holding the seam in place while resisting the abrasion, acids and chemicals found on packing floors.
• Seam integrity under load: High tenacity combined with low shrinkage keeps the bag closing seam tight and flat, so closures survive palletising, handling and long-haul transport without opening.
• Colour and label customisation: MH dyes this bag closing thread to customer colour references and offers private-label cone and carton marking for distributors building their own thread programmes.
• Reliable factory supply: As a Chinese thread manufacturer, MH runs bag closing thread as a standing production line, supporting repeat bulk supply and OEM programmes for packaging converters and bag closing machine dealers.
